XTM4208AS8CT from XTX, in a SOP-8. 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 | VDD | power_in | Supply pin; the recommended operating supply is 2.4 V to 18 V, the absolute maximum is -0.3 V to 20 V, and the bypass capacitor should be placed as close to this pin as possible. |
| 2 | OUTB | output | Full-bridge output B; continuous output current is 0.5 A and peak output current is limited to 0.8 A. |
| 3 | GND | power_in | Ground pin; the motor ground traces should be isolated from other ground connections in the layout. |
| 4 | OUTA | output | Full-bridge output A; continuous output current is 0.5 A and peak output current is limited to 0.8 A. |
| 5 | INB | input | Logic input B for PWM control; input voltage range is 0 V to 5 V, with VIH minimum 2.0 V, VIL maximum 0.6 V, and absolute maximum 5.5 V. |
| 6 | NC | unconnected | No connection; leave floating. |
| 7 | NC | unconnected | No connection; leave floating. |
| 8 | INA | input | Logic input A for PWM control; input voltage range is 0 V to 5 V, with VIH minimum 2.0 V, VIL maximum 0.6 V, and absolute maximum 5.5 V. |
