Monolithic Digital IC
LB1630
Low-Saturation Bidirectional Motor Driver
for Low-Voltage Applications
Overview
The LB1630 is a low-saturation bidirectional motor
driver IC for use in low-voltage applicaions. It is especially suited for use in small-sized low-voltage motors
for printers, cassette tape recorders, and consumer
equipment.
Features
• Capable of operating from a low voltage (2.5V min).
Low current drain at the srandby mode (ICC≤30µA).
• Low-saturation voltage (upper transistor + lower
transistor residual voltage 1.2V max at 400mA).
• On-chip spark killer diodes.
