5-Pin 碌P Supervisory Circuits with
Watchdog and Manual Reset
________________General Description
The MAX6316鈥揗AX6322 family of microprocessor (碌P)
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
CC
. Resets are
guaranteed valid for V
CC
down to 1V.
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鈥揗AX6322 are offered in a miniature
5-pin SOT23 package.
