LB1938FA  
Monolithic Digital IC  
1ch, Low-saturation  
Forward/Reverse Motor Driver  
http://onsemi.com  
Overview  
The LB1938FA is an H-bridge motor driver that supports low-voltage drive and features low-saturation outputs in an  
ultraminiature slim package. The LB1938FA 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.  
Features  
• Ultraminiature Micro8 package  
• The low saturation voltage means that the voltage applied to the motor is higher and IC heat generation is reduced.  
This allows this IC to be used in environments with higher ambient operating temperatures.  
Output saturation voltage (high side + low side): V sat = 0.15V typical (I = 100mA)  
O
O
• The wide usable voltage range and the low standby mode current drain of 0.1 µA make this IC optimal for battery  
operated equipment.  
• There are no constraints on the relationship between the input signal voltage and the supply voltage. For example,  
this IC can be use at V  
= 3V and V = 5V.  
CC  
IN  
• Thermal protection circuit limits the drive current and prevents the IC from causing a fire or being destroyed if the  
IC 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.

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.  
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating  
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
