MAX6394

High-Accuracy μP Reset Circuit

General Description

Beneﬁts and Features

● ±0.6% Threshold Accuracy at T = +25°C

The MAX6394 low-power CMOS microprocessor (μP)

supervisory circuit is designed to monitor power supplies in

μP and digital systems. It offers excellent circuit reliability

by providing 1% accurate thresholds over temperature and

by eliminating external components and adjustments. The

MAX6394 also provides a debounced manual reset input.

● ±1.0% Threshold Accuracy from -40°C to +125°C

●

Small SOT143 Package

● Open-Drain RESET Output Can Exceed V

● Precision, Factory-Set V

Reset Thresholds:

Nine Options from 2.4V to 4.8V

This device performs a single function: it asserts a reset

signal whenever the V

preset threshold or whenever manual reset is asserted.

RESET remains asserted for an internally programmed

interval (reset timeout period) after V

supply voltage falls below a

● Four Reset Timeout Periods Available:

0.7ms, 14ms, 105ms, and 826ms (minimum)

● Immune to Short V Transients

● 5μA Supply Current

the reset threshold or manual reset is deasserted. The

MAX6394’s open-drain RESET output can be pulled up

● AEC-Q100 Qualified, Refer to Ordering Information

to a voltage higher than V

for Specific /V Part

The MAX6394 comes with factory-trimmed reset threshold

voltages from 2.4V to 4.8V. Preset timeout periods of

0.7ms, 14ms, 105ms, and 826ms are also available. The

device comes in a SOT143 package.

Ordering Information appears at end of data sheet.
