Pololu Reverse Voltage Protector

The Pololu Reverse Voltage Protector safeguards your devices by protecting connected loads from reverse voltages down to -60 V. Unlike traditional diodes, this module does not block reverse current, making it ideal for energy-recovering applications like motor control. It utilizes the LM74500-Q1 reverse voltage protection controller and an N-channel MOSFET to achieve high efficiency with minimal power loss.

5381-005

Operating from 4 V (3.2 V after startup) to 60 V, the module supports continuous currents up to 12 A, with short bursts of up to 40 A. Its compact design offers compatibility with various connectors and optional transient voltage suppression for added flexibility.
