  • DRV8307 Using of Hall element at EVM

    Resolved
    Other Parts Discussed in Thread: DRV8307EVM Hi, My customer tries to operate motor with DRV8307EVM. They use the hall element. it is "HW-105W". VM=24V. At this case, What are we select at JP3 and JP4? I think think that we select the following. Is…

  • RE: DRV8307: BLDC starts and spins up to speed, but then shuts off and coasts

    Hi Russell, Are you using the DRV8307EVM? If not, can you provide a schematic? What is your system voltage? What is the time between LOCKn and the device losing lock? Are you monitoring FAULTn? What are you motor parameters?

  • RE: Looking for a BLDC motor driver IC with 3 linear hall-effect sensor input

    Hi John, I have not verified this solution on linear halls. The concept is used for hall sensors which have a single output indicating a logic zero or one. The DRV8307EVM and DRV8308EVM shows how to connect either a hall element (2 output hall)…

    Part Number: DRV8307 Hello, I have developed a dual BLDC motor controller PCB. The PCB design basically implements the DRV8307EVM twice on a single PCB excluding the SN74CBT3244CBTCPW switch network. The BLDC motors have single-ended hall sensors wired…

  • DRV8307 BLDC motor driving problem

    Hi, I am trying to drive my bldc motor with my own drv8307 board and DRV8307 EVM board. My bldc motor normal current is 1.45 A ( and it draws this normal current with DRV8307EVM board and there is no problem with DRV8307EVM board) , but with my own…

  • RE: DRV8307: I have designed drv8307 motor driver as same as 8307EVM i finding large current drawn from customized board as compared to EVM board

    Resolved
    Hello Adarsh, What large current draw value are you expecting in your new board? what is the current value under the same conditions in the DRV8307EVM? Do you have the same layout as the DRV8703EVM on your board? if so, can you set PWM input of your…

  • RE: DRV8307 Using Motor > 32V

    Resolved
    Thanks for your reply, Wilson. I've ordered a DRV8307EVM and I'll consider the best way to connect and evaluate this option. Kind regards

  • RE: DRV8307: Hall sensor spacing

    Hi Rick, Thanks for the reply. I have tested two motors on the DRV8307EVM; one is a 4-pole rotor/6-pole stator with halls spaced at 60deg and the other is a 14-pole rotor/12-pole stator with halls spaced at 120 deg. It's the 14-pole motor that doesn…

  • RE: DRV8307 Direction problem

    Lukasz, sorry to hear it isn't working. There clearly appears to be a problem with the phase or Hall wiring, or the Hall polarity. For the trial-and-error approach, the DRV8307EVM has 2 jumpers that make it easy to try each Hall polarity. Or if you can…
