ShangHai Consonance Elec · LED Drivers · SOT-89-5

CN5611 from ShangHai Consonance Elec, in a SOT-89-5. 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 VDD power_in Positive supply input, 2.7V to 6V. Also powers the internal control circuitry. Absolute maximum pin voltage -0.3V to 6.5V.
2 GND power_in Ground / power return. Should be tied to a large copper pour for thermal dissipation.
3 LED output LED cathode connection. Internal power transistor sinks the regulated constant current (up to 800mA) from the LED cathode to GND. Dropout voltage ~135mV at 200mA, ~410mV at 700mA.
4 ISET input Constant LED current setting pin. Connect a resistor R_ISET between ISET and VDD; I_LED = 910V / R_ISET (e.g. 4.55kΩ sets 200mA). 1% metal-film resistor recommended.
5 NC unconnected No internal connection. Leave floating or tie to GND.

CAD (KiCad official)

  • Symbol: CN5611
  • Footprint: Package_TO_SOT_SMD:SOT-89-5
  • 3D model: SOT-89-5 (KiCad packages3D, STEP)
  • 3D model files: cn5611-etched.step / cn5611-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn5611.step / cn5611.glb are the bare package body.

Provenance

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

  • Datasheet: ShangHai Consonance Elec datasheet (8 pp, sha256 2fadadd407e8a63b, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
