IRS20124S(PbF)
OC Output Signal
The OC pin is a 20 V open drain output. The OC
pin is pulled down to ground when an over current
condition is detected. A single external pull-up
resistor can be shared by multiple IRS20124 OC
pins to form the ORing logic. In order for a micro-
processor to read the OC signal, this information
is buffered with a mono stable multi vibrator to
ensure 100 ns minimum pulse width.
Because of unpredictable logic status of the OC
pin, the OC signal should be ignored during power
up/down.
Limitation from Body Diode in MOSFET
When a Class D stage outputs a positive current,
flowing from the Class D amp to the load, the body
diode of the MOSFET will turn on when the drain
to source voltage of the MOSFET become larger
than the diode forward drop voltage. In such a
case, the sensing voltage at the Vs pin of the
IRS20124 is clamped by the body diode. This
means that the effective R
DS(ON) is now much lower
than expected from R
DS(ON) of the MOSFET, and
the Vs node my not able to reach the threshold
to turn the OC output on before the MOSFET fails.
Therefore, the region where body diode clamping
takes a place should be avoided when setting V
SOC-
.

IC please refer to AN-978 and DT98-2a. For fur-
ther application information for class D applica-
tion, please refer to AN-1070 and AN-1071.
