DRV10970: Trapezoidal Commutation With 0° Hall Placement

Part Number: DRV10970


How does one configure the DRV10970 to work in trapezoidal commutation with 0° Hall placement? Table 4 of the data sheet offers only the 30° option for trapezoidal commutation.

The comment says in Table 4 says

The Trapezoidal motor with 0° Hall placement
may use 30 degree Hall delay (OTP setting) to
achieve optimum driving.

Does "OTP setting" mean that a variant of the DRV10970 with special firmware is needed? Is such a device available?

With reference to the question "DRV10970 Datasheet" started July 15, 2016, I notice that the DRV10970 data sheet has not yet been updated with Table 2.

  • Hi Bjorn,

    Sorry for delayed response.

    There is only one version of DRV10970 available. Some of the configuration can be changed through the pins CMTMOD and DAA.

    You can use 30 degree commutation for 0 degree hall placement without any problem.
