FOperation notes

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

BA6796FP

(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).

FElectrical characteristic curves

%Bias drop muting&

Muting also occurs when the bias pin voltage (26 pin) is

lowered below 1.4V (typically). Be sure the voltage stays

between 1.6V and 6.5V during normal operation.

(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) Attach a 0.1µF bypass capacitor to the power sup-

ply, at the base of the IC.

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