Dual/Triple, Ultra-Low-Voltage, SOT23 µP

Supervisory Circuits

General Description

The MAX6715A–MAX6729A/MAX6797A are ultra-low-volt-

age microprocessor (µP) supervisory circuits designed to

monitor two or three system power-supply voltages. These

devices assert a system reset if any monitored supply falls

below its factory-trimmed or adjustable threshold and main-

tain reset for a minimum timeout period after all supplies rise

above their thresholds. The integrated dual/triple supervisory

circuits significantly improve system reliability and reduce

size compared to separate ICs or discrete components.

These devices monitor primary supply voltages (V

from 1.8V to 5.0V and secondary supply voltages (V

from 0.9V to 3.3V with factory-trimmed reset threshold

voltage options (see the

Reset Voltage Threshold Suffix

Guide).

An externally adjustable RSTIN input option

allows customers to monitor a third supply voltage down

to 0.62V. These devices are guaranteed to be in the cor-

rect reset output logic state when either V

1 or V

remains greater than 0.8V.

A variety of push-pull or open-drain reset outputs along

with watchdog input, manual-reset input, and power-fail

input/output features are available (see the

Selector

Guide

). Select reset timeout periods from 1.1ms to

1120ms (min) (see the

Reset Timeout Period Suffix

Guide).

The MAX6715A–MAX6729A/MAX6797A are avail-

able in small 5-, 6-, and 8-pin SOT23 packages and oper-

ate over the -40°C to +125°C temperature range.

Note:

The first “_ _” are placeholders for the threshold voltage

levels of the devices. Desired threshold levels are set by the part

number suffix found in the Reset Voltage Threshold Suffix Guide.

The “_” after the D is a placeholder for the reset timeout delay

time. Desired delay time is set using the timeout period suffix

found in the Reset Timeout Period Suffix Guide. For example, the

MAX6716AUTLTD3-T is a dual-voltage supervisor V

1 =

4.625V, V

2 = 3.075V, and 210ms (typ) timeout period.
