LA5692S

Manufacturer Part Number
LA5692S
Description
Voltage regulator driver with watchdog timer
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : EN2770B
Overview
The LA5692 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 LA5692 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).
Applications
• Microcomputer system for car equipment, refrigeration/
Functions
• Output voltage 5V control.
• Watchdog timer.
• Reset generation at power-ON mode.
• Reset hold output [RES (2)] (Cleared with CK reinput).
Features
• An external PNP transistor can be used to provide a low-
• CK input with edge detector.
• Variable detection voltage.
• The watchdog time can be made longer.
