Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0M | input | Negative input of AMP0 (current-sense amplifier channel 0). |
| 2 | VREF | power_in | ADC reference voltage output that needs an external 1 µF or larger capacitor to ground, used only for internal digital and analog circuits and not to supply external circuits. |
| 3 | EU/HUP | input | Phase U back-EMF divider input in sensorless mode, and positive input of the phase U differential Hall signal or switch-Hall input in sensored mode. |
| 4 | A1M/HUM | input | Negative input of AMP1, and negative input of the phase U differential Hall signal. |
| 5 | A1P/HVP | input | Positive input of AMP1, and positive input of the phase V differential Hall signal. |

| 9 | A2M | input | Negative input of AMP2. |
| 10 | VBUS | power_in | DC bus voltage input after resistor divider. |

| 25 | HW | output | 6N pre-driver PWM output for the W-phase high-side power switch. |
| 26 | VBW | power_in | W-phase high-side bootstrap supply; VBW relative to VSW is specified at a maximum of 18 V. |
| 27 | VDRV | power_in | 6N pre-driver supply, 7 V to 18 V, decoupled with an external 1 µF to 10 µF capacitor. |
