17 / 43 page  VNI8200XP-32 Reverse polarity protection DocID027849 Rev 3 17/43 6 Reverse polarity protection Reverse polarity protection can be implemented on board using two different solutions: 1. Placing a resistor (RGND) between IC GND pin and load GND 2. Placing a diode between IC GND pin and load GND If option 1 is selected, the minimum resistance value has to be selected according to the following equation: RGND ≥ VCC / IGND where IGND is the DC reverse ground pin current and can be found in Section 4: "Maximum ratings" of this datasheet. Power dissipated by RGND (when VCC < 0: during reverse polarity situations) is: PD = (VCC) 2/R GND If option 2 is selected, the diode has to be chosen by taking into account VRRM >|VCC| and its power dissipation capability: PD ≥ IS*VF In normal conditions (no reverse polarity), due to the diode, there is a voltage drop between GND of the device and GND of the system. Figure 3: Reverse polarity protection This schematic can be used with any type of load. |
