Voltage Regulator Driver
with Watchdog Timer
Overview
The LA5693 is a single-chip voltage regulator for
microcomputer system monitor use that performs the
functions of 5V output voltage control, watchdog timer,
and voltage detector. Since the LA5693 can hold the reset
output, it is especially suited for use in peripheral control
and monitor output applications (example : valves used in
refrigeration equipment, hot water supply system).
