Overview
Five-Channel CD Actuator Driver (BTL: 4 channels, H bridge: 1 channel)
The LA6565 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 LA6565 to support a wide range of applications.
Application
* Five-channel (BTL: 4 channels, H bridge: 1 channel) CD motor driver
Features and Functions
* * * * * * * * Five power amplifier channels on a single chip (Bridge connection (BTL): 4 channels, H bridge: 1 channel) IO max: 1 A 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
