APPLICATIO S I FOR ATIO
Reverse Polarity Input Voltage Protection
DRAIN-BULK
DIODE OF FET
In some applications, protection from reverse polarity
voltage on V CC is desired. If the supply voltage is high
enough, a series blocking diode can be used. In other
cases, where the voltage drop must be kept low, a P-channel
V IN
