LB1830M

Low-Saturation Bidirectional Motor Driver

for Low-Voltage Applications

Overview

The LB1830M is a low-saturation bidirectional motor driver IC
with brake function for use in low-voltage applications. As
both of forward and reverse outputs are regulated, it is
especially suited for use in portable equipment such as VCR,
camera.

Features

.

Wide operating voltage range: 3.0 to 9.0 V

.

Low saturation voltage: 0.2 V at IO= 40 mA (typ)

.

Low current drain at standby mode (0.1 µA or less)

.

Brake function

.

Regulated voltage value (forward/reverse) setting available
by one variable resistor

.

Regulated output/saturation output switching available

.

Built-in spark killer diodes
