Applications
Overview
The LA6569 is a 5-channel driver for optical disc drives that includes a regulator on/off circuit.
Features
• Power amplifier 5-channel built-in. (Bridge-connection (BTL) : 4-channel, H bridge : 1-channel)
• IO max 1A.
• Level shift circuit built-in (except H bridge).
• Mute circuit (output ON/OFF) built-in.
(Operable with BTL AMP with MUTE1 : CH1 and MUTE2 : CH2 to 4 and not operable for the H bridge of 3.3VREG.)
• 3.3V regulator built-in (external PNP transistor).
• With a function to set the loading output voltage.
• Overheat protection circuit (thermal shutdown) built-in.
• Regulator ON/OFF circuit built-in.

*4. Voltage difference between both ends of load (8Ω). Output saturated.
*5. Output ON with MUTE : [H] and OFF with MUTE : [L] (HI impedance).
*6. The source of input OP-AMP is a constant current. As the 11kΩ resistance to the next stage is a load,
pay due attention when setting the input OP-AMP gain.
*7. Short (GND) brake used. SINK side output ON.
*8. 3.3VREG incorporates a drooping protection circuit and operated when the base current is 10mA (TYP).
*9. The output is 3.3V when the REG-EN pin is HIGH.
