HA16117F, HA1 Datasheet - Hitachi Semiconductor

HA16117F CMOS Watchdog Timer

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. Also referred to as watchdog timers, these devices are essential in systems that aim for high leve.

HA16117F 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 input signal

* Independent auto-reset high and low times (tRH and tRL)

* Watchdog monitoring by frequency filtering (indepen
