LV8082LP

Overview

The LV8082LP is a Constant-voltage 1ch + Constant-current 1ch driver that supports low-voltage operation. It is optimal

for constant-voltage and constant-current drive of voice coil motors (AF and Shutter) in portable equipment such as

camera cell phones.

Features

• Constant-voltage 1ch + Constant-current 1ch H-bridge driver

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

• 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

Block Diagram

Constant-voltage calculation : VOUT = VC × 2 Example : When an VOUT of 2V is required, VC must be 1V

Constant-current calculation : IOUT = 0.1 ÷ RF Example : When an IOUT of 100mA is required, RF must be 1Ω.

Usage Notes

The constant current is set by the resource RF connected between RFG and grou nd acc o rding to the fo r mula shown

above.
