LB1832V中文资料三洋数据手册PDF规格书

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.

特性 Features

• Supports low-voltage drive.

— When the same power supply is used for VCC and

VS: VCC = VS = 1.6 V min.

— When different power supplies are used for VCC and

VS: VS = 1.0 V min, VCC = 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)
