LK116

LANKE · Brushed DC Motor Drivers · SOT-23-6

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.
