New higher-power reverse voltage protector and ideal diode
 |
We are excited to announce the release of two new higher-power reverse voltage protectors that can handle up to around 25 A continuous while protecting your 4V–60V circuit from accidental destruction from reverse voltage:
- Reverse protection only – This version protects against reverse voltage while still allowing reverse current, making it suitable for applications such as battery-powered motor control where delivering energy back into the battery is desirable.
- Reverse protection with reverse current blocking – This version acts as an ideal diode, preventing current from flowing from output to input.
These boards feature larger 5×6mm MOSFETs with lower on-resistances and more than double the current carrying ability of the versions we released a few months ago, which makes the overall module larger (but still compact!):

Pololu Reverse Voltage Protectors are available in 20A/25A (left) and 10A/12A (right) versions. |

With these new releases, we now have six total reverse protector options (with or without reverse current blocking in three different power levels):
