DRV8847: Current regulation at independent bridge operation

Part Number: DRV8847

Hello team,

Can I use current reguration in independent bridge mode (Half bridge operation)?

On the datasheet, it seems like not possible because ISEN12 and ISEN34 is connected to GND.

If not possible, would it be possible to suggest similar device, which can?

Best Regards,
Kei Kuwahara

  • Hi Kuwahara-san,

    It is possible to implement current regulation in independent 1/2-Bridge mode. The diagram is showing a case of driving a relay or solenoid coil where current regulation is not implemented, however a current sense resistor can be connected to ISEN12 or ISEN34 for current regulation for driving a BDC or stepper motor. 

    Best,
