Part Number: DRV8307 Other Parts Discussed in Thread: DRV8308 ,
Tool/software:
I have a design that functions well at temperatures -10C or higher. However, I have test that consistently fails on multiple samples at -15C.
The motor simply does not…
Part Number: DRV8307 Hi, I've designed a BLDC motor driver board with DRV8307. MOSFETs are FDS6670 and the motor is MAXON EC45 30 watt with hall sensor and encoder. I attached only hall sensors to the motor driver, not the encoder to anywhere. Arduino…
Part Number: DRV8307 Other Parts Discussed in Thread: MCT8316Z , DRV10970 Hi,
A dual output hall sensor is used in section 8.1.1 of the DRV8307 datasheet. I searched, but I could not find a double output (negative and positive) product in the market…
Part Number: DRV8307 Tool/software: I have a design that functions well at temperatures -10C or higher. However, I have test that consistently fails on multiple samples at -15C.
The motor simply does not start up, and the motor driver faults out. I…
Part Number: DRV8307 I am using the DRV8307 to drive a BLDC (brushless DC) motor with 3 Hall sensors distributed at 120 degrees. The motor provides high torque at high speeds, but the torque is significantly reduced at low speeds. How can I increase the…
Part Number: DRV8307 Tool/software: Hi,
I have a board using the DRV8307 and the application requires running the motor to 6000rpm.
One of the motors we tried was a 57BL521 rated at 24VDC6000rpm, it was custom made for us from this company https:…

Part Number: DRV8307 Dear Expert
Good day!
Our customer want to test the driver signal , so they set the test condition below:
1.Do not connect the Motor
2.Short the Rsense to GND.
3.Supply the Hall signal external ,
They found that , the…
Part Number: DRV8307 Other Parts Discussed in Thread: DRV10987 , DRV10987EVM , DRV10974 , DRV10978 , MCF8316A Hi team,
Here's an issue from the customer may need your help:
The DC brushless cavity motor uses a photoencoder to measure speed and the…
Part Number: DRV8307 Hi Team,
Customer would like to know
what is the duty cycle of the minimum input 20kpwm waveform of drv8307 to have drive waveform output? He tested that a duty cycle greater than 4% was required to output a waveform to drive…
