FOperation notes (pin Nos. are those for the BA6898S)
(1)
Relationship between mute and reset output
Regulator voltage drop
If the regulator voltage drops to 4.0V (Typ.) or below, the reset output turns low and the
. . . . .
mute turns on. If the voltage then rises again to 4.2V (Typ.), the reset output turns high
and the mute turns off.
Bias voltage drop
If the bias pin (pin 3) voltage lowers to 1.4V (Typ.) or below, the mute turns on and the
. . . . . . . . . .
reset output turns low. For normal operations, have the voltage at 1.6V or greater.
Thermal shutdown
When the chip temperature reaches 175
_C (Typ.), the mute turns on and the reset output
. . . . . . . . .
turns low. If the chip temperature then drops below 150
_C (Typ.), then the mute turns off
and the reset output turns high.
Mute (pin 15)
If the mute pin (pin 15) voltage is open or lowers to 0.5V or below, the mute turns on but
. . . . . . . . . . . . .
the reset output does not change.
(2)
If the voltage of the thermal shutdown, mute ON, or
bias pin drops, or if the regulator voltage drops, the mute
is activated; however, in these situations, only the drivers
are muted. Also, the output pin voltage becomes the in-
ternal bias voltage (approx. (VCC
*VF) / 2).
(3)
Connect a bypass capacitor (approx. 0.1
F) be-
tween the bases of the power supply pins of this IC.
(4)
Even though pins 16 and 32 are connected to
ground within the package, be sure to also connect them
to a ground externally as well.
(5)
The capacitor connected between the regulator
output pin (pin 14) and GND also serves to prevent os-
cillation, so be sure to use a capacitor with excellent ther-
mal characteristics.
(6)
If the regulator is not used, short the regulator out-
put pin (pin 14) to VCC and have the pin for the externally
connected transistor base (pin 13) open.
(7)
Of the ground pins, only pin 18 is not connected to
the IC substrate. Therefore, design the PC board pattern
so that the potential of GND pin 18 does not go below the
substrate GND (including transient conditions).
