Monolithic Digital IC
LA6575H
Five-Channel Driver (four BTL
channels plus one H bridge channel)
for MD and CD Player
Overview
The LA6575H is a five-channel motor driver IC for MD and CD players with four BTL channels and one H bridge
channel for the loading motor. It features a built-in 5 V regulator circuit.
Functions and Features
• Four power amplifier channels plus one H bridge channel
• IO max: 700 mA (each channel)
• Built-in level shifting circuits for the BLT amplifiers
• One muting circuit system (output on/off control): applies to the BTL amplifiers
• Thermal protection circuit (Thermal shutdown circuit)
• Separate loading block power supply
• Built-in 5 V regulator

Note
1: The output are in the high-impedance state in this mode
2: In brake mode, the sink side transistors are on (short-circuit braking). The VLO and VLO levels go to a level essentially the same as the
ground level.
