Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VM | power_in | Motor power supply input, 4.5V to 45V operating range; bypass with 0.01µF ceramic and bulk capacitor to GND. |
| 2 | PGND | power_in | Power ground, internally shorted to other PGND pin; connect to system ground. |
| 3 | AOUT1 | output | Phase A motor winding output with 1.5A full-scale and 2.4A peak current capacity. |
| 4 | AOUT2 | output | Phase A motor winding output with 1.5A full-scale and 2.4A peak current capacity. |
| 5 | BOUT2 | output | Phase B motor winding output with 1.5A full-scale and 2.4A peak current capacity. |
| 6 | BOUT1 | output | Phase B motor winding output with 1.5A full-scale and 2.4A peak current capacity. |
| 7 | PGND | power_in | Power ground, internally shorted to other PGND pin; connect to system ground. |
| 8 | VM | power_in | Motor power supply input, 4.5V to 45V operating range; bypass with 0.01µF ceramic and bulk capacitor to GND. |
| 9 | GND | power_in | Device ground; connect to system ground for proper circuit operation. |
| 10 | DVDD | power_in | Internal 5V regulator output for logic circuits; bypass with 0.47µF to 1µF X7R ceramic to GND. |
| 11 | nFAULT | output | Open-drain fault indicator output pulled low on fault condition; maximum 5mA at 0.4V output. |
| 12 | VREF | power_in | Current reference input, 0.05V to 3.3V maximum; 2.2V/A transconductance gain for full-scale current. |
| 13 | nSCS | input | Serial chip select input active low with internal pull-up to DVDD; 50ns setup and hold time. |
| 14 | VSDO | power_in | Power supply for SDO output buffer, 2.9V to 5.5V range; selects output logic level. |
| 15 | SDO | output | Serial data output push-pull stage; data shifted on SCLK rising edge with 30ns propagation delay. |
| 16 | SDI | input | Serial data input sampled on SCLK falling edge with 20ns setup and 30ns hold time requirement. |
| 17 | SCLK | input | Serial clock input with 100ns minimum period; timing reference for SPI data transfer. |
| 18 | STEP | input | Step input; rising edge advances microstepper one step with internal pull-down; up to 500kHz, 970ns minimum pulse. |
| 19 | DIR | input | Direction input; logic level sets stepper direction with internal pull-down; 200ns setup before STEP rising edge. |
| 20 | DRVOFF | input | Motor output disable control; high disables H-bridge outputs, low enables; internal pull-up to DVDD. |
| 21 | nSLEEP | input | Sleep mode input; high enables device operation, low enters low-power sleep at 2µA; 75µs sleep time. |
| 22 | CPL | passive | Charge pump negative switching node; connect 0.022µF X7R ceramic capacitor between CPL and CPH pins. |
| 23 | CPH | passive | Charge pump positive switching node at 400kHz; connect 0.022µF X7R ceramic capacitor to CPL pin. |
| 24 | VCP | power_out | Charge pump output for high-side FET gate drive; connect 0.22µF 16V X7R ceramic capacitor to VM. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
