reverse polarity protection vn808cm-e 12/21 doc id 11456 rev 8 6 reverse polarity protection this schematic can be used with any type of load. the following is an indication on how to dimension the r gnd resistor. r gnd = (-v cc ) / (-i gnd ) where -i gnd is the dc reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. power dissipation in r gnd (when v cc < 0: during reverse polarity situations) is: pd = (-v cc ) 2 /r gnd note: in normal condition (no reverse polarity) due to the diode there will be a voltage drop between gnd of the device and gnd of the system. figure 7. reverse polarity protection status input i gnd output i + vcc r gnd load diode status input i gnd output i + vcc r gnd load diode
