MAX6346UR38+ - Maxim Integrated Products, Inc.

General Description

The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/

MAX6348 microprocessor (µP) supervisory circuits moni-

tor the power supplies in µP and digital systems. These

devices provide excellent circuit reliability and low cost

by eliminating external components and adjustments

when used with 2.5V, 3V, 3.3V, and 5V powered circuits.

These circuits perform a single function: they assert a

reset signal whenever the VCC supply voltage declines

below a preset threshold, keeping it asserted for at least

100ms after VCC has risen above the reset threshold.

The only difference between the devices is their output.

The MAX6326/MAX6346 (push-pull) and MAX6328/

MAX6348 (open-drain) have an active-low reset output.

The MAX6327/MAX6347 have an active-high push-pull

reset output. All of these parts are guaranteed to be in

the correct state for VCC down to 1V. The reset compara-

tor is designed to ignore fast transients on VCC. Reset

thresholds are factory-trimmable between 2.2V and

4.63V, in approximately 100mV increments. Twenty-one

standard versions are available. Contact the factory for

availability of nonstandard versions.

Ultra-low supply currents (1µA max for the MAX6326/

MAX6327/MAX6328) make these parts ideal for use in

portable equipment. All six devices are available in

space-saving SOT23 and SC70 packages.

MAX6348 are available in factory-set VCC reset thresholds from

2.2V to 4.63V, in approximately 0.1V increments. Choose the

desired reset-threshold suffix from Table 1 and insert it in the

blank spaces following “R.” There are 21 standard versions with

a required order increment of 2500 pieces. Sample stock is gen-

erally held on the standard versions only (see the Selector

Guide). Required order increment is 10,000 pieces for nonstan-

dard versions (Table 2). Contact factory for availability. All

devices available in tape-and-reel only.

Devices are available in both leaded and lead-free packaging.

Specify lead-free by replacing “-T” with “+T” when ordering.

____________ Applications Information

Interfacing to µPs with

Bidirectional Reset Pins

Since the RESET output on the MAX6328/MAX6348 is

open drain, these devices interface easily with micro-

processors (µPs) that have bidirectional reset pins,

such as the Motorola 68HC11. Connecting the µP

supervisor’s RESET output directly to the microcon-

troller’s (µC’s) RESET pin with a single pull-up resistor

allows either device to assert reset (Figure 1).

Negative-Going VCC Transients

In addition to issuing a reset to the µP during power-up,

power-down, and brownout conditions, these devices

are relatively immune to short-duration, negative-going

VCC transients (glitches).

The Typical Operating Characteristics show the Maxi-

mum Transient Duration vs. Reset Threshold Overdrive

graph, for which reset pulses are not generated. The

graph shows the maximum pulse width that a negative-

going VCC transient may typically have when issuing a

reset signal. As the amplitude of the transient increas-

es, the maximum allowable pulse width decreases.

Figure 1. Interfacing to µPs with Bidirectional Reset Pins
