GND protection network against reverse battery
This section provides two solutions for implementing a ground protection network against
reverse battery.
3.1.1
Solution 1: resistor in the ground line (R
GND
only)
This first solution can be used with any type of load.
The following formulas indicate how to dimension the R
GND
resistor:
1.

)
2.

)
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 battery situations) is:
P

= (-V

/ R
GND
This resistor can be shared among several different HSDs. Please note that the value of this
resistor is calculated with formula (1), where I
S(on)max
becomes the sum of the maximum on-
state currents of the different devices.
Please note that if the microprocessor ground is not shared by the device ground, the R
GND
produces a shift (I
S(on)max
* R

) in the input thresholds and the status output values. This
