General Description
The MAX6895–MAX6898 is a family of small, low-power,
voltage-monitoring circuits with sequencing capability.
These miniature devices offer tremendous flexibility with
an adjustable threshold capable of monitoring down to
0.5V and an external capacitor-adjustable time delay.
These devices are ideal for use in power-supply
sequencing, reset sequencing, and power-switching
applications. Multiple devices can be cascaded for
complex sequencing applications.
A high-impedance input with a 0.5V threshold allows an
external resistive divider to set the monitored threshold.
The output asserts (OUT = high or OUT = low) when
the input voltage rises above the 0.5V threshold and the
enable input is asserted (ENABLE = high or ENABLE =
low). When the voltage at the input falls below 0.5V or
when the enable input is deasserted (ENABLE = low or
ENABLE = high), the output deasserts (OUT = low or
OUT = high). All devices provide a capacitor-program-
mable delay time from when the input rises above 0.5V
to when the output is asserted. The MAX689_A versions
provide the same capacitor-adjustable delay from when
enable is asserted to when the output asserts. The
MAX689_P devices have a 1µs propagation delay from
when enable is asserted to when the output asserts.
The MAX6895A/P offers an active-high enable input
and an active-high push-pull output. The MAX6896A/P
offers an active-low enable input and an active-low
push-pull output. The MAX6897A/P offers an active-
high enable input and an active-high open-drain output.
Finally, the MAX6898A/P offers an active-low enable
input and an active-low open-drain output.
All devices operate from a 1.5V to 5.5V supply voltage
and are fully specified over the 0°C to +125°C operat-
ing temperature range. Each device is available in an
ultra-small 6-pin µDFN (1.0mm x 1.5mm) package.

ENABLE
Active-High Logic-Enable Input. Drive ENABLE low to immediately deassert the output to its
false state (OUT = low or OUT = high) independent of VIN. With VIN above VTH, drive
ENABLE high to assert the output to its true state (OUT = high or OUT = low) after the
adjustable delay period (MAX689_A) or a 150ns propagation delay (MAX689_P).

ENABLE
Active-Low Logic-Enable Input. Drive ENABLE high to immediately deassert the output to its
false state (OUT = low or OUT = high) independent of VIN. With VIN above VTH, drive
ENABLE low to assert the output to its true state (OUT = high or OUT = low) after the
adjustable delay period (MAX689_A) or a 150ns propagation delay (MAX689_P).
22GND Ground
33IN
High-Impedance Monitor Input. Connect IN to an external resistive divider to set the desired
monitored threshold. The output changes state when VIN rises above 0.5V and when VIN falls
below 0.495V.
4—OUT
Active-High Sequencer/Monitor Output, Push-Pull (MAX6895) or Open-Drain (MAX6897).
OUT is asserted to its true state (OUT = high) when VIN is above VTH and the enable input is
in its true state (ENABLE = high or ENABLE = low) for the capacitor-adjusted delay period.
OUT is deasserted to its false state (OUT = low) immediately after VIN drops below VTH - 5mV
or the enable input is in its false state (ENABLE = low or ENABLE = high). The open-drain
version requires an external pullup resistor.
—4OUT
Active-Low Sequencer/Monitor Output, Push-Pull (MAX6896) or Open-Drain (MAX6898). OUT
is asserted to its true state (OUT = low) when VIN is above VTH and the enable input is in its
true state (ENABLE = high or ENABLE = low) for the CDELAY adjusted timeout period. OUT
is deasserted to its false state (OUT = high) immediately after VIN drops below VTH - 5mV or
the enable input is in its false state (ENABLE = low or ENABLE = high). The open-drain
version requires an external pullup resistor.
55
CDELAY
Capacitor-Adjustable Delay. Connect an external capacitor (CCDELAY) from CDELAY to GND
to set the IN to OUT (and ENABLE to OUT or ENABLE to OUT for A version devices) delay
period. tDELAY = (CCDELAY x 4.0 x 106) + 40µs. There is a fixed short delay (40µs, typ) for the
output deasserting when VIN falls below VTH.
66V
CC Supply Voltage Input. Connect a 1.5V to 5.5V supply to VCC to power the device. For noisy
systems, bypass with a 0.1µF ceramic capacitor to GND.

Detailed Description
The MAX6895–MAX6898 is a family of ultra-small, low-
power, sequencing/supervisory circuits. These devices
provide adjustable voltage monitoring for inputs down to
0.5V. They are ideal for use in power-supply sequenc-
ing, reset sequencing, and power-switching applica-
tions. Multiple devices can be cascaded for complex
sequencing applications.
Voltage monitoring is performed through a high-imped-
ance input (IN) with an internally fixed 0.5V threshold.
When the voltage at IN falls below 0.5V or when the
enable input is deasserted (ENABLE = low or ENABLE =
high), the output deasserts (OUT goes low or OUT goes
high). When VIN rises above 0.5V and the enable input is
asserted (ENABLE = high or ENABLE = low), the output
asserts (OUT goes high or OUT goes low) after a capaci-
tor-programmable time delay.
With VIN above 0.5V, the enable input can be used to
turn the output on or off. After the enable input is assert-
ed, the output turns on with a capacitor-programmable
delay period (A version) or with a 150ns propagation
delay (P version). Tables 1 and 2 detail the output state
depending on the various input and enable conditions.
Supply Input (VCC)
The device operates with a VCC supply voltage from
1.5V to 5.5V. To maintain a 1.75% accurate threshold,
VCC must be above 1.5V. When VCC falls below the
UVLO threshold, the output deasserts. When VCC falls
below 1.2V the output state cannot be determined. For
noisy systems, connect a 0.1µF ceramic capacitor from
VCC to GND. For the push-pull active-high output option,
a 100kexternal pulldown resistor to ground ensures
the correct logic state for VCC down to 0.
Monitor Input (IN)
Connect the center point of a resistive divider to IN to
monitor external voltages (see R1 and R2 of the Typical
Operating Circuit). IN has a rising threshold of VTH =
0.5V and a falling threshold of 0.495V (5mV hysteresis).
When VIN rises above VTH and ENABLE is high (or
ENABLE is low) OUT goes high (OUT goes low) after
the programmed tDELAY period. When VIN falls below
0.495V, OUT goes low (OUT goes high) after a 16µs
delay. IN has a maximum input current of 15nA so
large-value resistors are permitted without adding sig-
nificant error to the resistive divider.

Table 2. MAX6896/MAX6898 Output
Adjustable Delay (CDELAY)
When VIN rises above VTH with ENABLE high (ENABLE
low), the internal 250nA current source begins charging
an external capacitor connected from CDELAY to GND.
When the voltage at CDELAY reaches 1V, the output
asserts (OUT goes high or OUT goes low). When the
output asserts, CCDELAY is immediately discharged.
Adjust the delay (tDELAY) from when VIN rises above
VTH (with ENABLE high or ENABLE low) to OUT going
high (OUT going low) according to the equation:
tDELAY = CCDELAY x 4.0 x 10-6 + 40µs
where CCDELAY is the external capacitor from CDELAY
to GND.
For adjustable delay devices (A version), when VIN >
0.5V and ENABLE goes from low to high (ENABLE
goes from high to low) the output asserts after a tDELAY
period. For nonadjustable delay devices (P version)
there is a 1µs propagation delay from when the enable
input is asserted to when the output asserts. Figures 2
through 5 show the timing diagrams for the adjustable
and fixed delay versions, respectively.

Enable Input (ENABLE or

)
The MAX6895/MAX6897 offer an active-high enable
input (ENABLE), while the MAX6896/MAX6898 offer an
active-low enable input (ENABLE). With VIN above VTH,
drive ENABLE high (ENABLE low) to force OUT high
(OUT low) after the adjustable delay time (A versions).
For P version devices, when VIN > 0.5V and enable is
asserted, the output asserts after typically 150ns.
The enable input has logic-high and logic-low voltage
thresholds of 1.4V and 0.4V, respectively. For both ver-
sions, when VIN > 0.5V, drive ENABLE low (ENABLE
high) to force OUT low (OUT high) within 150ns typ.
Output (OUT or
OUT
)
The MAX6895 offers an active-high, push-pull output
(OUT), and the MAX6896 offers an active-low push-pull
output (OUT). The MAX6897 offers an active-high
open-drain output (OUT), and the MAX6898 offers an
active-low open-drain output (OUT).
Push-pull output devices are referenced to VCC. Open-
drain outputs can be pulled up to 28V.
Applications Information
Input Threshold
The MAX6895–MAX6898 monitor the voltage on IN with
an external resistive divider (see R1 and R2 in the
Typical Operating Circuit). R1 and R2 can have very
high values to minimize current consumption due to low
IN leakage currents (±15nA max). Set R2 to some con-
veniently high value (1M, for example) and calculate
R1 based on the desired monitored voltage using the
following formula:
where VMONITOR is the desired monitored voltage and
VIN is the detector input threshold (0.5V).

Pullup Resistor Values
(MAX6897/MAX6898)
The exact value of the pullup resistors for the open-
drain outputs is not critical, but some consideration
should be made to ensure the proper logic levels when
the device is sinking current. For example, if VCC =
2.25V and the pullup voltage is 28V, you would try to
keep the sink current less than 0.5mA as shown in the
Electrical Characteristics table. As a result, the pullup
resistor should be greater than 56k. For a 12V pullup,
the resistor should be larger than 24k. It should be
noted that the ability to sink current is dependent on the
VCC supply voltage.
Typical Application Circuits
Figures 6, 7, 8 show typical applications for the
MAX6895–MAX6898. Figure 6 shows the MAX6895
used with a p-channel MOSFET in an overvoltage pro-
tection circuit. Figure 7 shows the MAX6895 in a low-
voltage sequencing application using an n-channel
MOSFET. Figure 8 shows the MAX6895 used in a multi-
ple-output sequencing application.
Using an n-Channel Device for Sequencing
In higher power applications, using an n-channel device
reduces the loss across the MOSFETs as it offers a
lower drain-to-source on-resistance. However, an n-
channel MOSFET requires a sufficient VGS voltage to
fully enhance it for a low RDS_ON. The application in
Figure 7 shows the MAX6895 in a switch sequencing
application using an n-channel MOSFET.
Similarly, if a higher voltage is present in the system, the
open-drain version can be used in the same manner.
