DRV8323: Auto offset Calibration

Mikael Jacob

Part Number: DRV8323

Hi,

The DRV8323/DRV8323R devices can perform an automatic offset calibration through the SPI registers or CAL pin.

I want to use the calibration through the SPI register. Which state of the pin CAL ? Not connect, tied to GND, tied to 3.3V ?

Thanks,

Mikaël

Hi Mikaël,

If using SPI to calibrate, it is recommended to set the CAL pin to 0V.

Leaving the pin as a no connect will also work. There is an internal 100kOhm pulldown to GND.
