XL297
XINLUDA · Motor Driver ICs · SOP-20-300mil
XL297 from XINLUDA, in a SOP-20-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SYNC | bidirectional | Output of the on-chip chopper oscillator; SYNC pins of multiple XL297s are tied together, and an external clock source is injected here. |
| 2 | GND | power_in | Ground connection. |
| 3 | HOME | output | Open collector output that indicates the initial state (ABCD = 0101); the transistor is open when this signal is active. |
| 4 | A | output | Motor phase A drive signal for the power stage. |
| 5 | INH1 | output | Active low inhibit control for the driver stage of phases A and B, also used by the chopper to regulate load current when CONTROL is low. |
| 6 | B | output | Motor phase B drive signal for the power stage. |
| 7 | C | output | Motor phase C drive signal for the power stage. |
| 8 | INH2 | output | Active low inhibit control for the drive stages of phases C and D, with the same functions as INH1. |
| 9 | D | output | Motor phase D drive signal for the power stage. |
| 10 | ENABLE | input | Chip enable input; when low (inactive) INH1, INH2, A, B, C and D are brought low. |
| 11 | CONTROL | input | Control input defining chopper action: when low the chopper acts on INH1 and INH2, when high on phase lines ABCD. |
| 12 | Vs | power_in | 5V supply input, 4.75 V min to 7 V max. |
| 13 | SENS2 | input | Input for load current sense voltage from the power stages of phases C and D. |
| 14 | SENS1 | input | Input for load current sense voltage from the power stages of phases A and B. |
| 15 | Vref | power_in | Reference voltage for the chopper circuit that determines the peak load current, 0 to 3 V input range. |
| 16 | OSC | passive | RC network (R to VCC, C to ground) sets the chopper rate, f ≈ 1/0.69RC; grounded on all but one device in synchronized multi-XL297 configurations. |
| 17 | CW/CCW | input | Clockwise/counterclockwise direction control input, synchronized internally so direction can be changed at any time. |
| 18 | CLOCK | input | Step clock; an active low pulse advances the motor one increment, with the step occurring on the rising edge. |
| 19 | HALF/FULL | input | Half/full step mode select input; high selects half step mode, low selects normal or wave drive depending on translator state. |
| 20 | RESET | input | Reset input that restores the translator to state 1 (ABCD = 0101). |
