The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (5 mΩ), it supports currents up to 12 A continuous and 40 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5381

The module protects the load against reverse polarity to -60 V and blocks the flow of reverse current to the power supply. It uses the LM74700-Q1 ideal diode controller and a MOSFET transistor. Thanks to its low impedance (10 mΩ), it supports currents up to 10 A continuous and 00 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5382
