AEC-Q100 Qualified

The MAX6316–MAX6322 family of microprocessor (μP)

supervisory circuits monitors power supplies and micro-

processor activity in digital systems. It offers several com-

binations of push/pull, open-drain, and bidirectional (such

as Motorola 68HC11) reset outputs, along with watchdog

and manual reset features. The

Selector Guide

below lists

the specific functions available from each device.

These devices are available in 26 factory-trimmed reset

threshold voltages (from 2.5V to 5V, in 100mV increments),

featuring four minimum power-on reset timeout periods

(from 1ms to 1.12s), and four watchdog timeout periods

(from 6.3ms to 25.6s). Thirteen standard versions are

available with an order increment requirement of 2500

pieces (see

Standard Versions

table); contact the factory

for availability of other versions, which have an order

increment requirement of 10,000 pieces.

The MAX6316–MAX6322 are offered in a miniature 5-pin

SOT23 package.
