LA6565
Monolithic Linear IC
Five-Channel CD Actuator Driver
(BTL: 4 channels, H bridge: 1 channel)
Overview
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
