| Mar 15, 2023 at 0:24 | comment | added | Tom Carpenter | @VoltsAndNuts With the MOSFET the correct way round, current can flow through the body diode from the input to the output, applying power to the C pin which is what powers the IC. With the MOSFET reversed, this doesn't happen so the IC stays turned off. When you short the pins out, this applies power to C and the IC can turn on and then stay on. | |
