U5020M Digital Window Watchdog Timer Description The digital window watchdog timer, U5020M, is a CMOS integrated circuit. In application where safety is critical, it is especially important to monitor the microcontroller. Normal microcontroller operation is indicated by a cyclically transmitted trigger signal, which is received by a window watchdog timer within a defined time window. A missing or a wrong trigger signal makes the watchdog timer reset the microcontroller. The IC is tailored for microcontrollers which can work in both full-power and sleep mode. With an additional voltage monitoring (power-on reset and supply voltage drop reset) U5020M offers a complete monitoring solution for microsystems in automotive and industrial applications.
