PRODUCTION DATA.
The nPGD pin is an open drain connection that indicates when a VDS fault condition has occurred. If the SENSE pin voltage is higher than the OUT pin voltage the state of the nPGD pin will be high impedance. In the typical application, as shown in Figure 20, the voltage at the nPGD pin will be high during any VDS fault condition. The nPGD state is independent of the fault timer function. The resistance R4 should be selected large enough to safely limit the current into the nPGD pin. Limiting the nPGD low state current below 5 mA is recommended.
