Overview
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 m...
