Five-Channel Driver (four BTL
channels plus one H bridge channel)
for MD and CD Player
LA6574D
Overview
The LA6574D is a motor driver IC for MD and CD players with four BTL channels and one H bridge channel. The
LA6574D features a separate power supply for the H bridge block, an output adjustment pin, and a 3.3V regulator to
support a wide range of applications.
Features and Features
• Four power amplifier channels plus one H bridge channel
• I max: 700mA (each channel)
O
• Built-in level shifting circuits for the BLT amplifiers
• Thermal protection circuit (Thermal shutdown circuit)
• Separate loading block power supply
• Built-in 3.3V regulator
• Provides a dedicated pin for adjusting the loading block output
