DRV8886: DRV 8886 Input supply voltage range

Part Number: DRV8886
Other Parts Discussed in Thread: DRV8880, DRV8846

Hi,

We are using DRV 8886 for motor driver and it's input voltage range is 8 to 37V.

Since we are operating from battery also, our requirement of input voltage range is 6 to 30V.

we are looking for same pin configuration/specification with wide input range from 6V to 30V.

Please, suggest alternate to DRV8886 with same pin mapping.

Regards,

Harish.

 

  • Hi Harish,

    You did not mention the current requirement. There are a couple of similar devices available.

    The DRV8880 operates from 6.5V to 45V.
    The DRV8846 operates from 4 to 18V.
    Neither device has the same pin mapping. The pin mapping is unique to the DRV8886 because of the integrated current sensing.
  • Hi,

    Thanks for your immediate response.

    DRV 8886 is matching to our requirement, but voltage range is 8 to 37V.

    We wanted to use this IC for 8" and 4" thermal printer which operates in battery supply voltage range from 6 to 30V.

    For 8" printer voltage range is 24V. and for 4 " printer the require voltage range is 6 to 9.5V.

    Current rating required is 1.5A to 2A with inbuilt current sensing.

    Please suggest any alternate to DRV8886 with same pin mapping with wide input voltage range from 6 to 30V.

    Since we designed our board we expect same pin mapping.

    Regards,

    Harish.

  • Hi Harish,

    We do not have a pin compatible device that operates at 6V.

    When operating with a system voltage below 8V, one option is using a boost regulator to raise the DRV8886 voltage above 8V.
