MST1163TQ

MST · LED Drivers · TO-252

MST1163TQ from MST, in a TO-252. 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 VIN power_in External power supply input pin. Connects directly to the battery positive (typ. 9-24 V operating; 40 V absolute max, 51 V transient tolerant). Provides power for the internal regulator, driver and high-side output MOSFET.
2 VOUT output Flasher output pin. High-side switched output (RDS(on) typ. 60 mΩ) driving the bulb load. Current-limited to ~15 A; drives the lamp with a fixed flash rate (typ. 1.42 Hz) or double frequency when a bulb-out condition is detected (I < ~1.2 A).
3 CEXT passive External capacitor pin for the internal supply/bootstrap regulator (typ. 100 uF / 25 V per app circuit). Internal regulator turns on at VddNORM 6.5 V (rising) with 1.5 V UVLO hysteresis; max 20 V on this node.

  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: mst1163tq-etched.step / mst1163tq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mst1163tq.step / mst1163tq.glb are the bare package body.

Provenance

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

  • Datasheet: MST datasheet (6 pp, sha256 3b04b75cf59dacb0, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
