LK116 from LANKE, 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 | OUTA | output | Full-bridge output A drives the motor, with continuous output current limited to 1.0 A and peak output current to 2.0 A (VDD=6V, Ta=25℃). |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | INA | input | Control input A sets the H-bridge state, with VIH minimum 2.0 V, VIL maximum 0.8 V, and an internal 1.5 MΩ pull-down resistor. |
| 4 | INB | input | Control input B sets the H-bridge state, with VIH minimum 2.0 V, VIL maximum 0.8 V, and an internal 1.5 MΩ pull-down resistor. |
| 5 | VDD | power_in | Positive power supply input, recommended 2.2 V to 7.5 V, with an absolute maximum of 7.5 V. |
| 6 | OUTB | output | Full-bridge output B drives the motor together with OUTA, with the same current limits of 1.0 A continuous and 2.0 A peak. |
