CC1108ST

Cross chip · LED Drivers · SOT-23-5

CC1108ST from Cross chip, 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 VFB input LED drive current setting terminal. Connect an external resistor RFB between this pin and GND to program the constant output current: ILED = VFB / RFB, with VFB typically 150 mV (144-156 mV). Absolute max voltage -0.3 V to 5.5 V.
2 GND power_in Ground reference for the device. RFB feedback resistor returns to this pin.
3 DIM input PWM dimming control input with built-in 50 kΩ pull-up resistor to internal 5 V rail; may be left floating if dimming is not required (chip outputs maximum current). Logic levels: VIH >= 2.5 V, VIL <= 0.4 V. Absolute max voltage -0.3 V to 5.5 V.
4 VCC power_in Power supply input, 2.5 V to 24 V operating range (absolute max -30 V to 28 V). Features reverse-connection protection, with reverse leakage current below 10 uA at VCC = -30 V. For VCC >= 12 V direct-supply applications, a 1 kΩ series resistor is recommended to suppress hot-swap transients.
5 DRV output LED drive sink current output. Connects to the cathode of the LED string; sinks up to 200 mA continuous with a saturation drop of only ~175 mV. Absolute max voltage -0.3 V to 32 V. Leakage current below 1 uA when disabled.

  • 3D model files: cc1108st-etched.step / cc1108st-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cc1108st.step / cc1108st.glb are the bare package body.

Provenance

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

  • Datasheet: Cross chip datasheet (10 pp, sha256 f4fa14d08e0968f2, 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).
