FOperation notes
(1)
The output current is muted when the chip temperature
rises above 175_C (typically). When the chip tempera-
ture falls to 150_C (typically), the driver circuit starts up
again.

mute pin (pin 6) voltage or lowering it below 0.5V. During
normal use, pin 6 should be pulled up above 2.0V.
(3)

normal use.

GND also serves to prevent oscillation of the IC, so select
one with good temperature characteristics.
