TPS2412: No Vdd, but pin C has power

Alan Chang

Part Number: TPS2412

All,

I have a question about TPS2412 Vdd pin. Pin C (pin 6) connects a 12V always existing. Vdd (pin 1) ties same 12V source with a switch to turn ON/ Off.

if Vdd pin is turn off (no 12V source), is there leakage current from other pins? and what's gate voltage?

Hi Alan,

When Vdd pin is pulled low, Gate voltage will be pulled to GND.
Now in this scenario, there will be leakage currents from C and A as mentioned in datasheet.
