LB1832V
Low-Saturation 1.5-Channel 3 V Drive
Bidirectional Driver
Overview
The LB1832V is a bidirectional driver IC that includes an
on-chip low-voltage low-saturation 1.5-channel bridge and
is provided in a miniature package. It is therefore optimal
for cameras that use 3 V lithium batteries. This IC allows
direct drive from the control microprocessor and supports
control of standby, forward, reverse, and braking
operations for two motors, i.e. the film take-up and lens
drive motors, from three inputs.
