3-Pin, Ultra-Low-Power SC70/SOT

µP Reset Circuits

General Description

Features

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.

ꢀ Ultra-Low 1µA (max) Supply Current

(MAX6326/MAX6327/MAX6328)

ꢀ Precision Monitoring of 2.5V, 3V, 3.3V, and 5V

ꢀ Reset Thresholds Available from 2.2V to 4.63V

ꢀ Fully Specified Over Temperature

ꢀ 100ms (min) Power-On Reset Pulse Width

ꢀ Low Cost

These circuits perform a single function: they assert a

reset signal whenever the V

supply voltage declines

below a preset threshold, keeping it asserted for at least

100ms after V has risen above the reset threshold.

ꢀ Available in Three Versions: Push-Pull RESET,

Push-Pull RESET, and Open-Drain RESET

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

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.

Pin Configuration

†The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/

MAX6348 are available in factory-set V 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.
