mt9201.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

MT9201

Aerosemi · LED Drivers · SOT-23-6

MT9201 from Aerosemi, in a SOT-23-6. 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 SW output Switching node. Drain of the internal N-channel power MOSFET; connect to the switched side of the external boost inductor and the anode of the external Schottky diode. High impedance while the part is shut down. Absolute max SW voltage is 30V.
2 GND power_in Ground pin. Provides the return for the internal power NMOS source, control circuitry, and the external RCS current-sense resistor. Tie to a solid ground plane for both thermal dissipation and switching-noise integrity.
3 FB input Current-sense feedback input. Regulated to 200mV (194mV / 206mV min/max) against the internal reference. Connect the bottom of the LED string through a sense resistor RCS to GND to set LED current: I_LED = 0.2V / RCS. Absolute max 6V.
4 EN input Enable and PWM dimming input. Pull above 1.5V to enable the IC; below 0.4V shuts it down (<1uA). Accepts a 20kHz-1MHz unfiltered PWM dimming waveform so that average LED current is proportional to duty cycle. Leakage ±1uA typical, absolute max 6V.
5 OV input Over-voltage sense input. Connect to the top of the LED string / VOUT. When VOUT rises above the 28V OVP threshold (open-LED condition) the internal NMOS is turned off to protect the boost stage.
6 VIN power_in Power supply input, 3V to 24V operating range (25V absolute max). Powers the control logic and the internal boost NMOS via the external inductor. Must be decoupled to GND with a >=1uF ceramic capacitor placed close to the pin. UVLO ~2.6V with 100mV hysteresis.

Ordering variants

Same part, different packaging or reel option.

  • MT9201

CAD (KiCad official)

  • Symbol: MT9201
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: mt9201-etched.step / mt9201-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt9201.step / mt9201.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mt9201.step 97 KB You want the bare part, or you mark your own boards.
mt9201-etched.step 1.3 MB You want the part with MT9201 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 327 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance
