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)
