FOperation notes

(1) Output mode switch for loading motor driver

(VCC = 8V)

(2) Loading motor driver voltage setting

(ex: forward mode)

BA5936S

(3) The BA5936S contains a thermal shutdown circuit.

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 mute is released.

(4) By having the mute pin (pin 27) voltage open or low-

ered to 0.5V or below, the output currents (channels 1, 2,

4, and 5, and regulator) can be muted.

For normal conditions, have the voltage at pin 27 pull-up

to 2V.

(5) If the voltage of the bias pin (pin 24) drops below

1.4V (Typ.), the drivers (channels 1, 2, 4, and 5) are

muted. For normal conditions, have the voltage at 1.6V

or greater.
