HA16117F Product details

Description

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.

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 (independent of duty cycle).
High-precision low voltage detection (±2%).
Space- and weight-saving 8-pin SOP package HA16117F Series Ordering Information The HA16117F Series includes three I.
