FOperation notes

(1) Setting the tray motor driver voltage (forward mode)

BA6996FP

(2) Mute functions

%Thermal shutdown&

The output current is muted when the chip temperature

exceeds 175_C (typically).

%Supply voltage drop muting&

The internal circuits turn off when the supply voltage

drops below 4.3V (typically), and turn on again when it

rises above 4.5V (typically).

(3) Muting occurs during thermal shutdown and when

the supply voltage or bias pin voltage drops. In each

case, only the driver is muted. The output pin voltage dur-

ing muting is the internal bias voltage, roughly VCC–VF / 2.

(4) Be sure to connect the IC to a 0.1µF bypass capaci-

tor to the power supply, at the base of the IC.

(5) Connect the radiating fin to an external ground.
