APPLICATIU
Reverse Polarity Input Voltage Protection
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
MOSFET can be used (as shown in Figure 4).
