Part Number: DRV8303 We use a DRV8303 in one of our products. Sometimes there is an issue with current sensing.
Without any motor attached to our board an no motor voltage (PVDD) connected, the current sense output (SO1 and SO2) is not correct.
I…
Part Number: DRV8303 Hi Team,
Does DRV8303 have two directions mode? Can I change direction of BLDC motor with using DRV8303. For example, can motor turn direction of clockwise and counter clockwise.
Beat Regards, Tom Liu
Part Number: DRV8303 Hi team,
Here's an issue from the customer may need your help:
The customer is currently using a DRV8303 to drive a BLDC motor. There is an issue with current sensing. Without any motor attached to board and a motor voltage (PVDD…
Part Number: DRV8303 Hi team,
Here's an issue from the customer may need your help:
1) When driving a three-phase MOS tube, it was found that the device has a default current amplification factor of 10 V/V. The customer would like to know how to change…
Part Number: DRV8303 Other Parts Discussed in Thread: DRV8302 The customer would like to know is it possible to drive the motor with the DRV8303 but without SPI function to connect, just as the following figure shows:
The OVER Voltage alarm occurs…
Part Number: DRV8303 Other Parts Discussed in Thread: DRV8301 , In our application we need both DRV8301 and DRV8303 motor driver IC's. DRV8301 has an integrated buck converter. For our application, we do not require a buck converter. We have left the…
Part Number: DRV8303 Hi team,
Here's an issue from the customer may need your help:
The customer would like to drive a sensorless DC motor with the DRV8303 or the same chip, is there any recommend schemes available?
Could you help check this case…
Part Number: DRV8303 Other Parts Discussed in Thread: DRV8301 , Hi team,
The customer would like to know if the difference between DRV8301 and DRV8303 is only if there is an integrated BUCK circuit. Can the control code of the 8301 be used directly…
Part Number: DRV8300 Other Parts Discussed in Thread: DRV8303 I am designing a BLDC controller to run a 48V/15A motor from a battery pack rated at 63V. I will be using TOSHIBA TPH4R10ANL,L1Q 100V N Channel MOSFETs in H-bridge configuration.
Will the…
Part Number: DRV8303 Hi,
We have been designing a BLDC driver circuit with DRV8303CAR, however when we measure current waveform via the scope, the resulting waveform is not as expected. Moreover, motor does not run at all or stop unexpectedly with PWM…
