U6808B Product details

Description

The U6808B is designed to support the fail-safe function of a safety critical system (e.g., ABS).

It includes a relay driver, a watchdog controlled by an external R/C-network and a reset circuit initiated by an over and undervoltage condition of the 5-V supply providing a low-level reset signal.
