The MAX6316–MAX6322 family of microprocessor (µP)

supervisory circuits monitors power supplies and

microprocessor activity in digital systems. It offers sev-

eral combinations of push/pull, open-drain, and bidirec-

tional (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 specifically designed

to ignore fast negative transients on V

guaranteed valid for V

These devices are available in 26 factory-trimmed reset

threshold voltages (from 2.5V to 5V, in 100mV incre-

ments), featuring four minimum power-on reset timeout

periods (from 1ms to 1.12sec), and four watchdog time-

out periods (from 6.3ms to 25.6sec). Nine standard ver-

sions 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.
