PT7M7809 Datasheet (pt7m7xxx) Up Supervisor Circuits

Manufacturer: Pericom Semiconductor (now Diodes Incorporated)

Overview: |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Data Sheet PT7M7803/7809-7812/7823-7825/7342-7345 µP Supervisor Circuits Discription The PT7M7xxx family microprocessor (µP) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in µP systems. These devices reduce the plexity and number of ponents required to monitor power-supply and battery functions. The main functions are: 1. Asserting reset output during power-up, power-down and brownout conditions for µP system; 2. Detecting power failure or low-battery conditions with a 1.25V threshold detector; 3. Watchdog functions; 4. Manual reset.

This datasheet includes multiple variants, all published together in a single manufacturer document.
