FT118S

XTX · Motor Driver ICs · SOT-23-6

FT118S from XTX, in a SOT-23-6. 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 OUTB output Full-bridge output B; continuous output current is limited to 0 to 1.2 A and peak current to 2.0 A for the FT118S SOT23-6 variant.
2 GND power_in Ground pin for the device; the datasheet also specifies that motor ground wiring should be isolated in layout.
3 INB input Logic input B of the PWM interface; recommended input range is 0 to 5 V, with VINH minimum 2.0 V, VINL maximum 0.6 V, and absolute maximum -0.3 V to 5.5 V.
4 INA input Logic input A of the PWM interface; recommended input range is 0 to 5 V, with VINH minimum 2.0 V, VINL maximum 0.6 V, and absolute maximum -0.3 V to 5.5 V.
5 VDD power_in Power supply input; recommended range is 2.4 V to 7.2 V, with an absolute maximum of 8.0 V, and the bypass capacitor should be placed as close to this pin as possible.
6 OUTA output Full-bridge output A; continuous output current is limited to 0 to 1.2 A and peak current to 2.0 A for the FT118S SOT23-6 variant.
