What is the gate drive voltage of the MP5016H device?
The MP5016H has a GATE pin to provide an external N-channel MOSFET gate drive signal
for reverse-current protection (RCP). Three events can pull down the GATE voltage: VIN
below the under-voltage lockout (UVLO), the enable (EN) voltage below the low level
threshold, or thermal shutdown. If any of these conditions occur, GATE sinks the current from
the gate of the external MOSFET to initiate a fast turn-off. For 3.3V low input voltage applications, choose an external reverse-blocking MOSFET with a small gate threshold voltage (VGSth < 1.6V) to
reduce the voltage drop caused by the reverseblocking MOSFET.
Nothing in your answer tells me what is the gate drive voltage. 4.5V? 10V? Something else?
There is a picture in the datasheet of scope traces, looks like 5V to me
