Pin Description
1
GATE
Gate pin of the PChannel Power MOSFET
2
OUT
This signal drives the gate of a Pchannel Power MOSFET. It is controlled by the voltage level on the IN pin.
When an overvoltage event is detected, the OUT pin is driven to within 1.0 V of V
IN
in less than 20 sec
provided that gate and stray capacitance is less than 12 nF.
3, 7
GND
Circuit Ground
4
IN
This pin senses an external voltage point. If the voltage on this input rises above the overvoltage threshold
(V
TH
), the OUT pin will be driven to within 1.0 V of V
IN
, thus disconnecting the PChannel Power MOSFET.
The nominal threshold level is 4.725 V and this threshold level can be increased with the addition of an external
resistor between the IN pin and the adapter.
