TM1911

TM Shenzhen Titan Micro Elec · LED Drivers · SOT-23-6

TM1911 from TM Shenzhen Titan Micro Elec, 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 VDD power_in Chip power supply input; recommended supply range 4.5V to 24V (absolute maximum -0.3 to +28V).
2 GND power_in Chip ground.
3 PWM input PWM signal input for dimming at 100Hz to 20kHz, with absolute maximum voltage -0.3 to +6.5V.
4 SET passive External resistor connection that sets the output current (15 to 300mA), with absolute maximum voltage -0.3 to +6.5V.
5 OUT passive Constant-current output terminal sinking up to 300mA, with absolute maximum voltage -0.3 to +28V.
6 NC unconnected No connect (empty pin).
