Part Number: DRV8320 Hello
We are currently designing a high-power 3-phase inverter board (approx. 2KW) using the DRV8320SRTVR . We have manufactured a total of 4 prototype boards , and we are encountering a strange unit-to-unit variance and speed-dependent…
Part Number: DRV8320 Other Parts Discussed in Thread: CSD88599Q5DC Tool/software: Hi, TI expert
The customer configured the attached schematic using DRV8320(Motor Driver) and CSD88599Q5DC(FET).
When changing the switch frequency from 200Hz to 16KHz…
Part Number: DRV8320 Tool/software: On a three phase inverter (BLDC) and with Block (6-step) commutation, with Vishay TrenchFET, 60V max Vds, with a 48V bus, our schema is as follows:
One totem pole is PWM-ing (for power control) with complimentary…
Part Number: DRV8320 Tool/software: I want to control a BLDC motor using "sensored trapezoidal motor control" method. According to the motor commutation diagram, at any given time, two phases are energized while one phase is "disabled."
However, when…
Part Number: DRV8320 Tool/software: On page 13 of the DRV8320 datasheet the test condition for mode 2 on the 4-level inputs is specified as 45 kΩ ± 5% to tied AGND, however on page 15 it is specified as 47 kΩ ± 5%. Which of these values is correct?
Part Number: DRV8320 Other Parts Discussed in Thread: DRV8334 Hi Team,
If we use DRV8320 1xPWM mode, the minimum IO requirements from MCU is 3, is that right?
1 PWM control signal + 1 Brake + 1 direction
If we use fault pin, then add one more input…
Part Number: TMS320F280049C Other Parts Discussed in Thread: LAUNCHXL-F280049C , BOOSTXL-DRV8320S We are using LAUNCHXL-F280049C with BOOSTXL-DRV8320S EVM. We replaced the shunt current sensors with LEM sensors and made modifications in our code, we are…
Part Number: TMS320F280049C We are planning to replace the existing shunt current sensors with LEM sensors into unused A/D on the LaunchPad. I understand that I need modify the A/D locations and I also plan to modify #define USER_ADC_FULL_SCALE_CURRENT_A…
