Pololu Reverse Voltage Protectors are tiny 0.3"×0.5" modules that can be inserted between a power supply and its load to protect that load from damage in the case of accidental reversal of power polarity. They operate from 4 V (3.2 V after startup) to 60 V and provide protection from negative voltages down to -60 V. They are available in two different power levels (10 A or 12 A) and with or without reverse current blocking, providing four options in all:

Pololu Item #	Max current	On resistance	Reverse current blocking
#5380	10 A	< 10 mO	no
#5381	12 A	< 5 mO	no
#5382	10 A	< 10 mO	yes (ideal diode)
#5383	12 A	< 5 mO	yes (ideal diode)

The versions without reverse current blocking are suitable for use with loads that have the potential to send current back into the power supply, such as motors. The versions with reverse current blocking act as ideal diodes, preventing any current from flowing from the load back into the supply.

Note: Any voltage on the output will reduce the 60 V maximum rating. For example, if there is a large capacitor charged to 24 V on the ouput, the minimum negative voltage would be -36 V.
