Shunt Current Measurement

Other Parts Discussed in Thread: DRV8301, DRV8312

Dear Sir/Madam

I have a simple doubt about the shunt measurement in HVMTRKit and DRV8301 evaluation boards. Both boards use an operational based scheme in order to measure the phase currents, but these schemes have some diferences: HVMTRKit has an inverting scheme (Vadc = 1.65 - 8.25*Vsense), but DRV8301 board has a non inverting scheme (Vo = 1.65 + 20*Vsense). I have revised the hal.h (HAL_read AdcData) and I have not found any difference for DRV8301 board based code and the HVKit based code. I have not found out where this sign is take into account. My hardware is based basically in DRV8301 board, but it uses the current measurement scheme from HVMTRkit, so I need to reflect this change in the labs software.

Thank you in advance,

Borja Gómez
