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

Supervisory Circuits

General Description

Features

● V

(Primary Supply) Reset Threshold Voltages

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 superviso-

ry circuits significantly improve system reliability and reduce

size compared to separate ICs or discrete components.

CC2

from 0.79V to 3.08V

● Externally Adjustable RSTIN Threshold for Auxiliary/

Triple-Voltage Monitoring (0.62V Internal Reference)

● Watchdog Timer Option

• 35s (min) Long Startup Period

• 1.12s (min) Normal Timeout Period

● Manual-Reset Input Option

These devices monitor primary supply voltages (V

)

CC1

● Power-Fail Input/Power-Fail Output Option

(Push-Pull and Open-Drain Active-Low)

from 1.8V to 5.0V and secondary supply voltages (V 2)

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-

● Low Supply Current 14μA (typ) at 3.6V

● Watchdog Disable Feature

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

available in small 5-, 6-, and 8-pin SOT23 packages and

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

Typical Operating Circuit

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,
