Pololu item #:
5382
Brand:
Pololu
Status:
Rationed (Active and Preferred)
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.

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.

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.

This module uses an LM74700-Q1 reverse voltage protection ideal diode controller and N-channel MOSFET to provide protection from negative voltages down to -60 V. It operates from 4 V (3.2V after startup) to 60 V and has a VIN path impedance of approximately 10 mΩ when the MOSFET is on (i.e. when power is connected with the proper polarity), enabling currents up to around 10 A continuous (and up to around 30 A for a few seconds). This version acts as an ideal diode, blocking reverse current from output to input.
| Operating voltage | Max current | MOSFET on resistance | Reverse current blocking | Size |
|---|---|---|---|---|
| 4 V – 60 V* | 10 A | < 10 mΩ | yes (ideal diode) | 0.3″×0.5″ |
| * Operates down to 3.2 V after startup. | ||||

Supply power and ground connect to the VIN and GND side of the board, and the VOUT and GND pins connect to the load. If the supply is connected correctly, with its positive voltage on VIN, the power will pass through the board to VOUT. If the supply is connected incorrectly, with the positive voltage on GND, supply power will not pass through to the output, and any connected load will be protected from the reversed supply voltage.
The input and output slots can accommodate a variety of connectors, including 5mm-pitch terminal blocks, 3.5mm-pitch terminal blocks, 0.2″-pitch headers, and 0.1″-pitch headers.
