Power H Mini – DC 12A H-Bridge driver

(2 customer reviews)

The small yet powerful H Bridge DC driver board has a lot of great specs that make it useful for a wide variety of mechatronics. In particular the high current output and automotive grade reliability makes it good choice to use with almost any DC motor.


Output motor voltage range 4 to 28 V
Logic level on IN pins up to 5.5 V
Peak Current 12 A
Stand-by current (max) 1 µA


SKU: SAM-VNH7DC12A Categories: , Tag:


This board comes pre-assembled using the automotive grade VNH7100AS H-Bridge driver, incorporating a dual monolithic high-side driver and two low-side switches. Both switches are designed to efficiently integrate on the same die for a true Power MOSFET with intelligent signal/protection circuitry.

  1. James

    Great little board, used it with car side mirror motors for a neat solar tracker project

  2. SAM

    Did not burn out at 15 amps although got a bit hot as in frying bacon hot
