TIDUF36A May 2023 – December 2023 DRV8328
Figure 3-4 shows the Hall sensor interface from the motor to the board. The AVDD output from the DRV8328 gate driver is used as the power supply for the Hall sensor. Usually, the Hall sensors have an open drain or open collector configuration. R4, R5, and R6 are used as the pullup resistors. R9, R11, and R12, along with C21, C22, and C23, form noise filters at the Hall sensor input.
