These devices reduce the complexity and number of components required to monitor power-supply and battery functions. The main functions are: 1. Asserting reset output during power-up, powerdown and brownout conditions for P system. 2. Watchdog functions 3. Manual reset. Applications  Power-supply circuitry in P systems  Networking  Security System  Server/Storage  Embedded System Function Comparison Table Part No. 1 PT7M7803 2 PT7M7809 3 PT7M7810 4 PT7M7811 5 PT7M7812 6 PT7M7823 7 PT7M7824 8 PT7M7825 RESET output Push-Pull Open-Drain - - -- - -- - - - RESET output (push-pull)     Manual Reset Input     Watchdog Input   - All trademar...
