    Hi Andy,

    The recommended abs max for the DRV8212 is 11V and the absolute abs max is 12-V. if there are any voltage spikes above 12-V, it may cause voltage overstress on the device which may cause damage. For higher voltage ratings, I recommend the DRV8220 which has a max operating voltage of 18-V and current of 1.76-A. The DRV8220 is part of the same family of low power drivers as the DRV8212 so it has the same functionality and safety features.

    If possible, can you share who the customer is and if they have other requirements for their applications like current sensing etc. you can send me a private message if there is any sensitive information you don't wish to share in the public forum. You can also post to the internal forum.
