Ordering number : EN7559C
LA5693AM
Monolithic Linear IC
Voltage Regulator Driver
with Watchdog Timer
Overview
The LA5693AM 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 LA5693AM can hold the reset output, it is
especially suited for use in peripheral control and monitor output applications including valves used in refrigeration
equipment, hot water supply system. In addition, as the LA5693AM assures reliable operation over a wide range of
operating temperatures (-40 to +125°C), it can find many applications in microcontroller systems for use in automobiles
and other industrial equipment.
Features
• An external PNP transistor can be used to provide a low-saturation voltage regulator.
• Since the CK input has no edge detector, a high degree of flexibility is allowed in applications.
• Variable detection voltage.
• The watchdog time can be made longer.
Functions
• Output voltage 5V control.
• Watchdog timer.
• Power-ON reset function.
• Reset hold output [RES (2)] (Cleared with CK reinput).
