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
.
