FOperation notes BA6896FP internal thermal shutdown circuit. Output current muted when chip temperature exceeds 175_C (typically). output current muted raising mute (pin voltage above 2.2V. should open pulled above 0.4V during normal operation. Muting also occurs when bias pin) drops below 1.4V (typically). should stay above 1.6V during normal operation. internal circuits turn when supply voltage drops below 4.5V (typically) start again when supply voltage rises above 4.7V (typically).

Muting occurs during thermal shutdown, mute-on operations drop bias voltage supply voltage. each case, only drivers muted. During muting, output pins remain internal bias voltage, roughly (VCC*VF) Attach bypass capacitor (roughly 0.1µF) power supply, base radiating connected package's internal GND, should also connected external ground. capacitor between regulator output (pin also serves prevent oscillation select with good temperature characteristics.
