Completed Protection Circuit

If there is a need for window comparators for the voltage and current values, then two channels may be added to this design. Both of the channel outputs are combined by shorting both open-drain outputs together in what is referred to as AND configuration (when either outputs a logic low, the combined output is also low). To have distinct outputs, use a separate pullup resistor for the first channel of the TLV9022. Low-side current sensing with a 10-mΩ sense resistor was used to achieve overcurrent protection at 10A. If a smaller resistance or lower current threshold is needed, you can use an even smaller resistance in combination with an amplifier.
