thermal shutdown circuit. The output current is muted
when the chip temperature rises above 175_C (typically).
The driver circuit is restored when the chip temperature
rises above 150_C (typically).
(2)
mute pin voltage or lowering it below 0.5V. This pin
should be pulled up above 2.0V during normal operation.
(3)
below 1.4V (typically). This pin should stay above 2.0V
during normal operation.
