SANYO LB1638M, LB1638 Datasheet
Ordering number: EN3515A
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 I
500 mA, they have a low saturation output of V
0.75 V. They are especially suited for use in compact motor of
portable equipment.
