FAQ:- Q: Does this module support brushless and non-inductive BLDC?- A: Yes. The DRV8301 motor drive module features three-phase BEMF output which can be used to sample communication signal.- Q: Does it support ST FOC library?- A: Yes. In addition to two-channel chip internal current amplifier, the DRV8301 driver board features three-channel external current amplifier circuit to support ST FOC three-resistor current sampling mode.GND: GND nOCTW: nOCTWnSCS: nSCSSDO: SDODC-CAL: DRV8310 Internal Amplifier Input Short Circuit Switching SignalINH-A: Phase A High-side MOS Switch SignalINH-B: Phase B High-side MOS Switch SignalINH-C: Phase C High-side MOS Switch SignalSO-2: DRV8310 Internal Amplifier 2 OutputVPD D-O: Voltage Signal Output of Power Supply & Amplitude = 5.1/73.1 VP DDEMF-B: Phase B Back-EMF Output & Amplitude = 5.1/73.1 EMFIOUTA: Phase A Current Signal OutputIOUTB: Phase B Current Signal OutputIOUTC: Phase C Current Signal OutputPWRGD: DRV8301 DC-DC Operating Indication SignalnFAULT: DRV8301 Abnormal Indicator SignalSDI: SDISCLK: SCLKEN-GATE: DRV8301 Drive Enable, High-level EnableINL-A: Phase A Low-side MOS Switch SignalINL-B: Phase B Low-side MOS Switch SignalINL-C: Phase C Low-side MOS Switch SignalSO-1: DRV8301 Internal Amplifier 1 OutputEMF-A: Phase A Back-EMF Output & Amplitude = 5.1/73.1 EMFEMF-C: Phase B Back-EMF Output & Amplitude = 5.1/73.1 EMFEX-REF: Current differential amplifier reference level selects the internal or external reference level via R27, R28. The internal reference level is 3.3V, which means that the phase current is 0 when the phase current signal output is 1.65V. Setting example: When you want to set the current level signal with 2.5V as 0, it is needed to connect this pin to a 5V level, with R28 missing solder and R27 soldered to 0R resistor.REF+1.65V: Reference level output of external differential current amplifier. When using the on-board 3.3V reference level, this pin outputs a 1/2 reference level amplitude, which is 1.65V.
