U6813B Fail-safe IC With High-side And Relay DriverFail-safe IC, Watchdog Timer Relay Driver Lamp Driver and Charge Pump The function of Microcontrollers in safety-critical applications (e.g., anti-lock systems)
needs to be monitored permanently. Usually, this task is accomplished by an indepen-
dent watchdog Timer The monolithic IC U6813B designed in bipolar technology and
qualified according to the needs of the automotive industry, includes such a watchdog
Timer and provides additional features for added value. With the help of integrated
driver stages, it is easy to control safety-related functions of a relay and of an N-chan-
nel Power MOSFET in high-side applications. In case of a Microcontroller malfunction
or supply-voltage anomalies, the U6813B provides positive and negative reset and
enable output signals. This flexibility guarantees a broad range of applications. The
U6813B is based on of Atmels fail-safe ICs U6808B and U6809B By ATMEL Corporation
