Part Number: DRV10970EVM

Hi all

Would you mind if we ask DRV10970EVM?

There is the description "Add three external pulls resistors for hall input across three jumpers J5, J7, and J8" on the EVM's document.
What does it mean? Are these resistors VINT-U_HN, VI NT-V_HN and VINT-W_HN?
And, how much are these suitable for?1kohm?


Kind regards,

Hirotaka Matsumoto

  • Let me respond to you by the end of the day.
  • In reply to Sanmesh Udhayakumar:

    This description is for single-ended hall sensor.

    Basically you need t a pull up resistor for the hall outputs which are going into the DRV10970 negative hall inputs U_HN, V_HN, W_HN.

    The resistor value depends on the current needs of the halls in your motor. current = 5V/resistance
