DRV8889-Q1: question on open load detection

Scarlett Cao

Part Number: DRV8889-Q1

Hi team,

My customer found the OL bit is set in Fault status register (0X00), however the OL_A and OL_B in DIAG_2 (0X02) are still 0. Do you know what could possibly cause this?

Thanks

Hi Scarlett,

If OL bit is set high, OL_A or OL_B (or both) should be set 1 I think. I could not consider the possibility.
