MicroPower Microprocessor Reset Circuit
General Description
The APR3011/2/3 are designed to monitor voltage
supplies in µP and digital systems. The quiescent
current is extremely low, typically 1.5 µA, making it
ideal for portable battery operated equipment. The
APR3011/2/3 operate by monitoring the system
power supply voltage. When the input voltage drops
below a fixed threshold, the device asserts a reset
signal for a fixed time period after Vcc rises above
the fixed threshold. The APR3011/2/3 series is avail-
able with three output stage versions : APR3011
push-pull active low output, APR3012 push-pull ac-
tive high output and APR3013 open drain active low
output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3011/2/3 are come in
a miniature SOT-23, SOT-23-5, SOT-89 packages.

Application Information
VCC Transient Rejection
The APR301 1/2/3 have the function to reject the tran-
sient glitches from the power line. The Maximum Tran-
sient Duration vs. Reset Threshold Overdrive shows
at Typical Characteristics.The transient voltage with
the duration under the curve will not generate a reset
signal, e.g. a transient of 100mV below the reset
threshold voltage have the duration more than 35us, it
will generate a reset signal. Connect a 0.1uF bypass
capacitor to the VCC pin can improve the transient
immunity.
Reset Output
The APR3011/2/3 have 3 output stage versions:
APR3001 is an active low push-pull output, when the
VCC drops below the reset threshold, the RESET out-
put generates a low signal. APR3012 is an active high
push-pull output, when the VCC drops below the reset
threshold, the RESET output generates a high signal
(see Timing Chart). APR3013 is an active low open
drain output, the RESET output must be connected a
pull-up resistor to a supply voltage that is lower than
6V, it suits to use in multiple voltage systems (see
Figure 2). The APR3011 RESET output is valid until
the VCC=1.2V, below 1.2V the IC is shutdown, and
the output becomes a floating state. If it is a trouble, a
resistor should be connected from reset output to
ground to keep the reset output low (see Figure 1).
For The APR3012, a pull-up resistor to VCC is required
to keep the valid reset output for VCC below 1.2V.
