FT118 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 | NC | unconnected | Pin 1 is a no-connect (floating) pin and should be left unconnected. |
| 2 | INA | input | Logic input A controls the H-bridge (PWM IN/IN mode), with VINH min 2.0 V, VINL max 0.6 V, recommended input range 0 to 5 V, and absolute maximum -0.3 V to 5.5 V. |
| 3 | INB | input | Logic input B controls the H-bridge (PWM IN/IN mode), with VINH min 2.0 V, VINL max 0.6 V, recommended input range 0 to 5 V, and absolute maximum -0.3 V to 5.5 V. |
| 4 | VDD | power_in | Power supply input with recommended range 2.4 V to 7.2 V and absolute maximum -0.3 V to 8.0 V; the bypass capacitor should be placed as close to the VDD pin as possible. |
| 5 | OUTB | output | Full-bridge output B drives the motor, with continuous output current limited to 1.35 A (SOP8) and peak current limited to 2.5 A (FT118). |
| 6 | AGND | power_in | Analog ground pin, which must be connected to the system ground. |
| 7 | PGND | power_in | Power ground pin for the H-bridge, which must be isolated from the motor ground routing in layout. |
| 8 | OUTA | output | Full-bridge output A drives the motor, with continuous output current limited to 1.35 A (SOP8) and peak current limited to 2.5 A (FT118). |
