DRV8848: Alternate

Part Number: DRV8848
Other Parts Discussed in Thread: DRV8847

All,

I'm looking for a drop in replacement for the DRV8848 motor driver. Preferably one that has stock available, but I'll take all part numbers that work.

I was not able to find one that is pin for pin compatible. I'll take higher current ratings and lower current ratings down to 2Amps.

Thanks!

  • Hello, Matt,

    Can you change the sensing resistor value to get the different current setting. The close one is DRV8847.

  • Wang,

    Thanks for the reply. Yes, in fact, I don't even use the sense resistor. I connect it to ground directly.

    Unfortunately, this part is only 2Amps in parallel mode. I need 2 amps in a single half bridge. The minimum overcurrent trip on that part is 1.6Amps. I need it at 2Amps or above. Our application can draw up to 1.8Amps.

    Are there any other drivers with a pinout that is compatible? 


  • Matt,

    In that case, I didn't find a pin to pin compatible deive to replace DRV8848. If you can have a new design, I would recommend DRV8424P.
