Part Number: LM66100
Perhaps I am missing something, but I believe this device is supposed to behave a disabled p-channel mosfet when CE is pulled higher that Vout. However, in testing this, I still see a forward current when these conditions are met, which is not how a p-channel mosfet would behave.
Wiring:
Vin = 3.3v
CE = 5v
ST = GND
Vout = connected to a 3kOhm load to GND
Measuring the voltage drop across the load gives me 2.8V meaning there is still a large forward current flowing. I have repeated this test on multiple lm66100s and the results are consistent. Is this the expected behavior of the chip? Does it really only protect from reverse current when in the OFF state?
