# CP118SDTR

**XBLW** · Brushed DC Motor Drivers · SOP-8

CP118SDTR from XBLW, 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 | NC | unconnected | No connection; left floating (datasheet function: 悬空, floating). |
| 2 | INA | input | Logic control input A; together with INB it sets the bridge state (high threshold min 2.0 V, low threshold max 0.8 V, 1.5 MΩ typical internal pull-down). |
| 3 | INB | input | Logic control input B; together with INA it sets the bridge state (high threshold min 2.0 V, low threshold max 0.8 V, 1.5 MΩ typical internal pull-down). |
| 4 | VDD | power_in | Positive supply; recommended 2.2 to 7.5 V, absolute maximum 7.5 V, with a 104P capacitor to ground in the reference circuit. |
| 5 | OUTB | output | Full-bridge output B terminal driving the motor, continuous 1.6 A and peak 3.0 A maximum. |
| 6 | AGND | power_in | Analog ground, tied to ground together with PGND in the reference circuit. |
| 7 | PGND | power_in | Power ground, tied to ground together with AGND in the reference circuit. |
| 8 | OUTA | output | Full-bridge output A terminal driving the motor, continuous 1.6 A and peak 3.0 A maximum. |

## CAD (KiCad official)

- Symbol: `CP118SDTR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `cp118sdtr-etched.step` / `cp118sdtr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cp118sdtr.step` / `cp118sdtr.glb` are the bare package body.
