Overview
HA16117F Series
CMOS Watchdog Timer
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.
Also referred to as watchdog timers, these devices are essential in systems that aim for high levels of crash protection.
Fabricated by a CMOS process, they consume little power and are ideally suited for batteryoperated systems.
These ICs are available in versions for industrial and communications equipment and automotive applications, as well as for consumer products.
Functions
• Power-on reset Sends a RES signal to the MPU for a fixed time...
