LB1935FA

Overview

LB1935FA is IC with forward/reverse motor drive 2-channel in which low saturation voltage and low voltage

operation possible. Its small sized package is optimal for 2 phase excitation drive of 2 phase bipolar stepping motors

for various portable devices such as digital still cameras.

Features

• Low saturation voltage, VO (sat) = 0.3V typ at IO = 150mA

• Built-in shoot-through current protection circuit

• No standby current consumption (or zero)

• Built-in thermal shutdown circuit

• Micro10 small-sized package

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.

Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high

current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
