BA5973FP

FOperation notes

(1)

The BA5973FP contains a thermal shutdown cir-

cuit.

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

up.

(2)

Connect a bypass capacitor (approx. 0.1

µF) be-

tween the bases of the power supply pins of this IC.

(3)

Be sure to connect the radiation fins to an external

ground.
