Operation notes
(1) BD7961FM has a built-in thermal shutdown circuit.
When the chip temperature reaches 175
°
C (Typ.), the output current from all drivers is muted.
When the chip temperature returns to 150
°
C (Typ.), the circuit of the driver unit starts up.
(2) When the mute terminal (pin33) is opened or the terminal voltage is reduced to 0.5V or less, the output current of the
BTL driver unit is muted.
In the normal state of use, pull up the voltage to 2.0V or more.
(3) When the voltage of the regulator switch terminals (pin8 and 9) is increased to 2.0V or more, the output from the
regulator is muted. In the normal state of use, pull down the voltage to 0.5V or less.
(4) When the bias terminal (pin36) voltage is reduced to 0.7V or less, the BTL driver unit is muted.
In the normal state of use, set the voltage to 1.1V or more.
(5) Thermal shutdown mutes all drivers. When the mute ON voltage and the bias terminal voltage are reduced, only the
BTL drivers are muted. When the drivers are muted, the BTL driver output terminal voltage becomes the internal bias
voltage (V
CC
1
0.7)/2V.
