It looks like the SFT1341 might turn off before the NCP300 does if gate voltage drops too low.I have NCP300 with sft1341 mosfet. I want to monitor my battery at 3V. Does attached circuit work. I have a confusion how P channel MOSFET works with NCP300. Could anybody explain me working of this circuit.
Thanks
Something like an IRLM110. Gate Threshold voltage is 1 to 2 Volts. The voltage needed to turn it on. The SFT1431 requires up to 4 Volts and may not turn on at all below 3.5 Volts.
NCP300 is surface mount? IRLM110 is too.
