    For single H-bridge that handles the 12V power supply, your best option is the following:

    If you can drop your supply down, the DRV8837 is a newly introduced device that will really get your cost and solution size down to a minimum and handles up to 11V:

    Hi MD,

    For 12V and less than 1A to drive a brushed DC motor you can take a look at DRV8800 and DRV8801. These are both single H Bridges which will operate at that voltage and current. If you have more than one motor to drive, I would look at DRV8802 which is a dual H Bridge capable of driving up to 1.6A per power stage.

    Do note all of these H Bridges use the PHASE / ENABLE interface which is different than the interface you propose, but still very easy to control.

    If you requite INx interfacing, you can take a look at DRV8841 and DRV8843, but these are higher current (2.5A per H Bridge), so the price will be higher than the three devices I mentioned earlier.

    Hope the info helps. Best regards,

    Jose Quinones
