TMI5102

TMI · LED Drivers · SOT-23-5

TMI5102 from TMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Chip enable pin. Drive above 1.5V (V_IH) to turn the part on; drive below 0.4V (V_IL) to turn it off. Do not leave floating. Leakage typ ±0.01µA, max ±1.0µA.
2 GND power_in Ground return pin for the device.
3 LX output Power switch node output - connection to the external step-down inductor. Internal high-side PMOS RDS(on) typ 120mΩ, low-side NMOS typ 70mΩ. Peak current limit 2.5A typ. Absolute max -0.3V to 6.5V (transients to -3.5V/+7.5V for <5ns).
4 VIN power_in Power supply input, 2.5V to 5.5V operating range (abs max 6.5V, OVP threshold 6.0V typ, UVLO threshold 2.3V typ). Must be closely decoupled to GND with a 10µF or greater ceramic capacitor.
5 FB input Feedback pin. Regulated feedback voltage is 100mV typical. A current-sense resistor R1 connected between FB and GND programs LED current per ILED = VFB / R1 (e.g. 50mΩ → 2A).

CAD (KiCad official)

  • Symbol: TMI5102
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tmi5102-etched.step / tmi5102-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi5102.step / tmi5102.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TMI datasheet (9 pp, sha256 71e737f96cf49106, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
