DRV11873: Do you have an alternative device?

Other Parts Discussed in Thread: DRV10974, DRV10964

Hi team,

We use DRV11873 with 6 pole pair.
We hope to drive 10800rpm but this device can't achieve this operation according to the https://e2e.ti.com/support/motor-drivers/f/38/p/314799/1096171#1096171, is that correct?

Because RPM=(FG*60)/pole pairs=(950*60)/6=9500rpm.

If 10800rpm can't be achieved, do you have an alternative device which is pin and function compatible?
When I searched TI.com, DRV10974 is same package but not same pin assignment.

Best regards,
Koyo

    Hi Koyo,

    Thanks for posting your question in MD forum. You're right about the maximum frequency limit in DRV11873. I would recommend you to try DRV10964 which is the only device that can support up to 1300 Hz electrical frequency. However, this device is not pin to pin compatible with DRV11873. We do not have any device in DRV10x family that is pin to pin compatible with DRV11873. 

    Regards,

    Vishnu.
