The LB1938T is an H-bridge motor driver that supports low-voltage drive and features low-saturation outputs in an

ultraminiature slim package. The LB1938T provides forward, reverse, brake, and standby modes controlled by two input

signals, and is an optimal DC motor driver for notebook personal computers, digital cameras, cell phones, and other

portable equipment.

• Ultraminiature MSOP8 package (3.0mm×4.9mm×0.93mm)

• The low saturation voltage means that the voltage applied to the motor is higher and IC heat generation is reduced.

• The wide usable voltage range and the low standby mode current drain of 0.1 µA make this IC optimal for battery

• There are no constraints on the relationship between the input signal voltage and the supply voltage. For example, this

• Thermal protection circuit limits the drive current and prevents the IC from causing a fire or being destroyed if the IC

This allows this IC to be used in environments with higher ambient operating temperatures.

IC can be use at V CC = 3V and V IN = 5V.

chip temperature reaches or exceeds 180°C due to large currents flowing when the outputs are shorted due to, for

example, motor layer shorting or other phenomena.
