Hitachi HA16117F

The HA16117F Series of ICs make a micro-processor (MPU) system fail-safe by monitoring its power supply to detect voltage drops, and monitoring a P-RUN (program running) pulse to detect system crashes. These ICs are available in versions for industrial and communications equipment and automotive applications, as well as for consumer products. The threshold differs for different ICs in the series, allowing designers to choose an IC matching system requirements (see ordering information) Features • Low power consumption : Operating (ACC pin low) = 0.5 mW (Typ) : Standby (ACC pin high) = 0.2 mW (Typ) • Watchdog timer on/off control by ACC...
