Overview

The LA6565 is a 4-channel BTL plus 1-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 LA6565 to support a wide range of applications.

Functions

•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
