Monolithic Digital IC
LB1638, 1638M Low-Saturation Bidirectional Motor Drive for Low-
Voltage Applications
Overview
The LB1638, 1638M are low-saturation bidirectional motor driver ICs for use in low-
voltage applications. At an IO of 500 mA, they have a low saturation output of VO (sat) = 0.75 V. They are especially suited for use in compact motor of portable equipment.
