LB1837M
Low-voltage/Low-saturation Bidirectional
Constant-Voltage Regulated Motor Driver
Overview
The LB1837M is a low-voltage, low-saturation, two-channel
motor driver with a bidirectional braking function that provides
constant-voltage regulated output for bidirectional operation.
The design of the LB1837M is ideal for video equipment,
cameras, and other portable equipment.
