Part Number: DRV8307 Other Parts Discussed in Thread: DRV8306 Hi,
I am using the DRV8307 to control a DPM 57BL74B1 motor at 30V. I drive the controller using ENABLEn and PWM, in a unidirectional way and without using the brake function, i also cut off…

Part Number: DRV8307 Hi,
I want to control BLDC motor with single ended Hall sensor. I am using the attached schematic for sensors but it doesn't work. Can anyone help me?
Thank you for your supports.
Part Number: DRV8307 Other Parts Discussed in Thread: DRV8308 Hi,
I am using the DRV8307 to spin a BLDC Motor that has a filter wheel attached to it.
In my software I watch for the LOCKn Signal to be set before performing any other functions.
The issue…
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…
thanks for the reply, i just wanted to ask that theoretically the DRV8307 will not allow high side & low side mosfets to be turned on at the same time. When the low side mosfet is on what will be the expected power dissipation assuming RDSON = Ron and…
Part Number: DRV8307 Other Parts Discussed in Thread: CONTROLSUITE Hi All, i see there is a pscpice transient analysis model available for DRV8307. can anyone please let me know if there are allegro layout files also available for the same or for the EVM…
Hey Cherry,
Glad to hear that the motor is now spinning.
Hmm is there a load difference between the clockwise/counterclockwise direction?
Also I am suspecting that this might be due to hall signals being misaligned.
Similar to post below:
Can you check…
Part Number: DRV8307 Hello
I am going to use drv8307 in my motor control design it has recommend frequency range from 16 to 50 kHz.Can this frequency varied between 16 to 50 kHz or it needed any constant frequency between 16 to 50 kHz
Adam.
I have two questions.
1. Is channel 1 wavwform of the below screenshot normal?
The waveform differ from the GHA wavwform(picture 35, page32) in the DRV8306 datasheet.
2. Some motor runs normally with other driver but does not run with DRV8307…
