Small 5-Pin SOT23 Package
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.
