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.
Features
• Supports low-voltage drive.
— When the same power supply is used for V_CC and
V_S: V_CC = V_S = 1.6 V min.
— When different power supplies are used for V_CC and
V_S: V_S = 1.0 V min, V_CC = 2.5 V min.
• Low saturation voltage (Upper side transistor plus lower
side transistor remaining voltage: 0.6 V (typ) at 1 A)
• Zero current drain in standby mode
• 1.5-channel bidirectional driver that can be directly
driven from the control microprocessor
• Separate logic and motor power supply connections
• Brake function
• Built-in spark killer diode
• Miniature package (SSOP-24)
