GATEP Control 引脚功能描述
GATEP has a 2M resistive pull-down to ground and a 5.8V Zener clamp in series with a 200k resistor to IN.
It controls the gate of an optional external P-channel MOSFET to provide negative voltage protection. The 2M
pull-down turns on the external P-channel MOSFET once VIN is more than the P-channel MOSFET gate threshold
voltage. The IN to GATEP Zener protects the external Pchannel MOSFET from gate overvoltage by clamping its
VGS to 5.8V when VIN goes high.
