Part Number:DRV8302
I am trying to make a very simple circuit for getting a motor to turn, but I like the current and voltage protection of the DRV8302
Two quick questions about this chip:
1. If I already have a stable power supply for my microcontroller, can I leave all the buck related pins disconnected?
2. If I am using hall effect sensors to determine motor position, can I eliminate the shunt resistors, and leave SP1, SN1, SP2, SN2, SO1, and SO2 disconnected, and DC_CAL permanently LOW (or disconnected), or are the shunt resistors needed for some of the internal operation of the chip? This way I would just drive the 6 input pins in a sequence as determined by my microcontroller and it's readings from the hall sensors.
Many thanks for your help
