BA5912AFP-Y
Operation notes
(1)
The BA5912AFP-Y contains a thermal shutdown
circuit. When the chip temperature reaches 175 C
(Typ.), the output current is muted. If the chip tempera-
ture then drops below 150 C (Typ.), then the mute is re-
leased.
(2)
By having the voltage of the mute pins (pins 2 and
13) open or lowered to 0.5V or below, you can indepen-
dently mute the output current for channels 1 and 2. For
normal conditions, have the voltages for the mute pins
(pins 2 and 13) pulled up to 2.0V or greater. If the both
mute pins (pins 2 and 13) are open or 0.5V or less, then
the IC automatically enters the standby mode.
(3)
If the voltage of the bias pin (pin 20) drops below
1.4V (Typ.), outputs are muted. For normal conditions,
have the voltage above 2.0V.
(4)
If the power supply voltage drops below 3.5V (Typ.),
internal circuits turn off. If the power supply voltage then
rises to 4.0V (Typ.), the circuits turn on.
(5)
bias pin drops, or if the power supply voltage drops, the
mute is activated; however, in these situations, only the
drivers are muted. Also, the output pin voltage becomes
the internal bias voltage.
(6)
When Pre V

, have the Vref switch pin
open or at 0.5V or less (internal bias voltage = (Pow

VF) / 2). When Pre V

(7)
Connect a bypass capacitor (approx. 0.1
μ
F) be-
tween the bases of the power supply pins of this IC.
(8)
Even though the radiation fins are connected to
ground within the package, be sure to also connect them
to a ground externally as well.
