| The digital window watchdog timer, K4S2808320-TC75, 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 K4S2808320-TC75 offers a complete monitoring solution for microsystems in automotive and industrial applications. |
