Sanyo LB1630 Specifications

Ordering number:EN1261E

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≤30 A).

•Low-saturation voltage (upper transistor + lower transistor residual voltage 1.2V max at 400mA).

•On-chip spark killer diodes.
