Overview
The LA6544M is a 4-channel bridge (BTL) driver developed for use in CD-ROM systems.

Functions
• Bridge connected (BTL) four-channel power amplifier
• VCE (residual voltage) minimized (channels 1 to 3) by using two power supplies.
• IOmax: 1.0 A
• Muting circuit provided (output on/off control) (MUTE pin: low for output off, high for output on. MUTE1: controls channel 1, MUTE2: controls channels 2, 3, and 4.)
• Thermal protection (shutdown) circuit
• Separated output stage power supply (VS1: channels 1, 2, and 3, VS2: channel 4)
