(1) The BA5973FP contains a thermal shutdown cir-
When the chip temperature reaches 175_C (Typ.), the
output current is muted. If the chip temperature then
drops below 150_C (Typ.), then the driver circuits start
(2) Connect a bypass capacitor (approx. 0.1µF) be-
tween the bases of the power supply pins of this IC.
(3) Be sure to connect the radiation fins to an external
