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)
•
IO max: 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

*1: The total current dissipation for VCCP1, VCCP2, and VCCS with no load.
*2: The input amplifier is a buffer amplifier.
*3: The voltage difference between the two sides of the load (12Ω).
*4: When the MUTE pin is high, the output will be on, and when low, the output will be off (high-impedance state).
*5: The input operational amplifier source is constant current. Since the 11kΩ resistor between this and the next stage functions as the load, the input
operational amplifier gain must be set carefully.
*6: The braking operation is a short (to ground) braking operation. The sink side output is on at this time.
*7: Design guarantee.
