Part Number: DRV8313
We currently use the DRV8313 on hundreds of robot drives with small BLDCs using 3 phase PWN channels and while its great I would love to lower the pin count for our micro controller.
IS there an alternative IC that would provide good control of a BLDC(robotic drive sensorless) without the 3 phase signal inputs?
With the current 3 phase signal we can operate the BLDCs with pretty good precision like a stepper motor so Id still be looking to keep that aspect of the design just reduce pin count. Perhaps i2c control?
Any suggestions welcome though I would like to avoid adding additional micro controllers to increase pin count
