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)

•IOmax: 1A

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

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

(The muting circuits operate for the BTL amplifiers. They do not apply to the H bridge or regulator circuits.)

•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
