3 Summary

Based on the load type, the reverse battery protection can be implemented either with a back-to-back power switch or with a forward load switch topology. Various reverse battery protection system design examples are based on TPS1211-Q1 and TPS1214-Q1 High side switch controllers, as described in this application note, can be adopted based on the load type.
