This module protects a connected load from reverse voltages down to -60 V. This version acts as an ideal diode, blocking reverse current from output to input.

Operating voltage1 Max current Resistance2 Reverse current blocking Size
4 V – 60 V 12 A < 5 mΩ yes (ideal diode) 0.3″×0.5″

Note 1: Operates down to 3.2 V after startup.
Note 2: MOSFET on resistance.

 

Pololu Reverse Voltage Protectors are compact 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 (green PCBs) or 75 V (red PCBs) and provide protection from negative voltages down to -60 V or -75 V, respectively. They are available in different power levels and with or without reverse current blocking:

The versions without reverse current blocking are suitable for applications such as battery-powered motor control where the ability to deliver energy back into the supply is desirable. The versions with reverse current blocking act as ideal diodes, preventing any current from flowing from the load back into the supply.
