LA6565VR

Overview

The LA6565VR is a four-channel BTL plus one-channel H bridge actuator driver developed for use in CD and DVD

drives. The BTL driver channels 1 and 2 include built-in operational amplifiers allowing the LA6565VR to support a

wide range of applications.

Functions and Features

• Five power amplifier channels on a single chip (Bridge connection (BTL): 4 channels, H bridge: 1 channel)

• I O max: 1A

• Built-in level shifters (except for the H bridge channel)

• Muting circuits (output on/off, two systems)

• Built-in regulator (Uses an external PNP transistor and is set with an external resistor.)

• Output voltage setting function (loading driver)

• Built-in independent operational amplifiers

• Thermal shutdown circuit
