LV49152V
Power supply lowering protection circuit
Since the instable operation in the low voltage is prevented by using this circuit, after the voltage of the PVD pin is
monitored and the voltage below the Attack voltage (PVD = 8V typ.), AMP is turned off.
Also, to prevent the instable operation when the voltage of the PVD pin is decreased by any cause during operations, the
Attack voltage (PVD = 7V typ.) is set.
The voltage of Attack and Recover has hysteresis (About 1V) to prevent ON/OFF continuous action of the power supply
lowering protection circuit.
Function image
Also, this IC is designed to turn off AMP in the same sequence that the MUTE is on as a pop noise measures when the
plug of products are put off.
Over current protection circuit
The over current protection circuit is a protection circuit * to protect the output DMOS from the over current and
corresponds to any mode of the power supply, GND and a load short.
The protection operation is performed when the current reaches the detection current value set out in IC and the output
DMOS is compulsorily turned off for about 20
μsec.
After compulsorily tuning off the output DMOS, when the Amplifier is automatically reset in usual operation and the over
current flows continuously, the protection operation is performed again.
Function image
* The over current protection circuit is a function to avoid the abnormal state like the output short-circuit temporarily.
Unfortunately, we cannot guarantee that IC is not destroyed.
