LA5693AM

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).
