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 1.12s), and four watchdog timeout

periods (from 6.3ms to 25.6s). Thirteen 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.
