FOperation notes

1) The thermal shutdown circuit mutes the output cur-

rent when the chip temperature rises above 175_C (typi-

cally). Hysteresis width is set at 25_C (typically), and

muting is canceled when the chip temperature drops be-

low 150_C.

2) The output current can be muted by raising the ex-

ternal mute pin above 2.0V. Pin 14 should be pulled down

below 0.5V during normal operation.

3) Muting occurs during thermal shutdown and exter-

nal muting. In each case, only the drivers are muted. Dur-

ing muting, the output pins remain at the internal bias

voltage, roughly (VCC / 2).

4) Connect the IC to a 0.1µF bypass capacitor to the

power supply, at the base of the IC.

5) Connect the radiating fin to an external ground

(BA6195FP-Y).
