LV8080LP

Overview

The LV8080LP is a two-channel constant-current driver that supports low-voltage operation. It is optimal for

constant-current drive of stepping motors (AF and zoom) in portable equipment such as camera cell phones.

Features

• Two channels constant-current H-bridge driver

• Built-in power supply switch and position detection comparator for use with a photoreflector

• Supports both 2-phase drive and 1-2 phase drive.

• Implemented in a low-power MOS IC process.

• Ultraminiature easy to solder VCT16 package (2.6 × 2.6mm)

• Built-in thermal protection and low-voltage sensing circuits

14 PI/PR A switch, with NMOS open-drain output, used to turn

on/off the power supply of the position sensor unit. When

using this switch, connect the position sensor unit

between this pin and the VCC pin.

On/off control of this switch is accomplished by CONT

pin. Setting the CONT pin high turns on the switch.
