The MAX6316–MAX6322 family of microprocessor (µP) supervisory circuits monitors power supplies and microprocessor activity in digital systems. It offers several combinations 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 in the full data sheet); 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.
