TM1814

TM Shenzhen Titan Micro Elec · LED Drivers · SOP-8

TM1814 from TM Shenzhen Titan Micro Elec, in a SOP-8. 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 OUTR output Red-channel constant-current output. N-channel open-drain sink; 64-step programmable constant current 6.5 mA-38 mA, 256-level PWM dimming. Rated up to 32 V; recommended OUT-on voltage 1.2-3 V for best efficiency; enters constant-current region above ~0.8 V.
2 OUTG output Green-channel constant-current output. N-channel open-drain sink; 64-step programmable constant current 6.5 mA-38 mA with 256-level PWM. Absolute max 32 V; channel-to-channel matching ±3%.
3 OUTB output Blue-channel constant-current output. N-channel open-drain sink; 64-step programmable constant current 6.5 mA-38 mA with 256-level PWM. Absolute max 32 V.
4 GND power_in Ground / power supply return. All voltages are referenced to this pin.
5 DO output Single-wire cascade data output. Forwards regenerated data to the DIN of the next TM1814 in the chain; held high before forwarding starts. Recommend 100 Ω series resistor for ESD/hot-plug protection. Propagation delay DIN→DO ~155 ns.
6 DIN input Single-wire cascade data input. Receives NRZ-coded control data (C1 current setting + C2 inverse + Dn PWM values) at up to 800 kHz. VIH ≥ 3.5 V, VIL ≤ 1.5 V at VDD=5 V. Recommend 100 Ω series resistor for ESD/hot-plug protection.
7 VDD power_in Logic power supply, 4.5-6.5 V typical (5.0 V nominal). Integrates an internal 5 V zener regulator so the chip can operate from a 6-24 V rail through an external series resistor (R = (VDC - 5.5 V) / 10 mA). Bypass with a 104 (100 nF) decoupling cap close to the pin. Abs-max 7.0 V.
8 OUTW output White-channel constant-current output. N-channel open-drain sink; 64-step programmable constant current 6.5 mA-38 mA with 256-level PWM. Absolute max 32 V.

Pins 8

CAD (KiCad official)

  • Symbol: TM1814
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: tm1814-etched.step / tm1814-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tm1814.step / tm1814.glb are the bare package body.

Provenance

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

  • Datasheet: TM Shenzhen Titan Micro Elec datasheet (10 pp, sha256 4287ea6b25920461, 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.
