Description
The digital window watchdog timer, U5020M, is a CMOS integrated circuit. In applica-
tions 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 causes the watchdog timer to reset the microcon-
troller. 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), the U5020M offers a complete monitoring solution for microsystems in
automotive and industrial applications.
