DRV8870: Solenoid operation using DRV8870

Part Number: DRV8870
Other Parts Discussed in Thread: DRV8871

Hi all

Would you mind if we ask DRV8870?

Our customer would like to operate solenoid using DRV8870.
Could you refer to the attachment file?
20190109_DRV8870.pdf

We assume that it is possible to configure it.
If there is some problem, could you give us the advice? 

Kind regards,

Hirotaka Matsumoto

    Hi Matsumoto-san,

    It is possible to configure the DRV8870 to change the current.

    Using VREF would be simpler and smaller since the component sizes are smaller.

    The DRV8871 could also be used. The Ilim resistor can be changed to adjust the current, and the larger current sense resistor is not required.
