Key Features
- During power-up or when the VCC power supply falls outside selectable tolerance limits, both RESET and RESET become active
- The trip point tolerance signal, TOL, selects the trip level tolerance to be either 10% or 20%
- A debounced manual reset input, PBRST, activates the reset outputs for a minimum period of 250ms
- There is a watchdog timer to stop and restart a microprocessor that is “hung-up”
- The watchdog timeouts periods are selectable: 150ms, 610ms, and 1200ms
