pads.json symbol: the part is a 6-lead SOT-23 (DDC) - the shipped footprint has 6 pads and the datasheet agrees - but the symbol carried an 8-pin pinout padded with NCs. Pinout taken from this part's datasheet for its own ordering suffix. The library failed validate because the symbol declared pins the footprint has no pad for (connect-pad-unresolved), which also blocked its orderable attributes.

tps3700ddcr.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

TPS3700DDCR

Texas Instruments · Comparators · SOT-23-6

TPS3700DDCR from Texas Instruments, 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 OUTA output Open-drain output A. Asserts (pulls low) when SENSEA drops below the internal 400 mV reference (undervoltage detection). Requires an external pull-up resistor to the desired logic rail.
2 GND power_in Device ground reference. Connect to system ground.
3 NC unconnected No internal connection. May be left floating or tied to GND.
4 SENSEB input Overvoltage sense input B. Compared against the internal 400 mV reference; OUTB asserts when SENSEB exceeds the reference. Drive from a resistor divider off the monitored rail. Input bias current is ~10 nA typical.
5 SENSEA input Undervoltage sense input A. Compared against the internal 400 mV reference; OUTA asserts when SENSEA falls below the reference. Drive from a resistor divider off the monitored rail. Input bias current is ~10 nA typical.
6 NC unconnected No internal connection. May be left floating or tied to GND.
7 VDD power_in Supply input. Operating range 1.6 V to 18 V. Bypass with a 0.1 uF ceramic capacitor to GND close to the pin.
8 OUTB output Open-drain output B. Asserts (pulls low) when SENSEB rises above the internal 400 mV reference (overvoltage detection). Requires an external pull-up resistor to the desired logic rail.

CAD (KiCad official)

  • Symbol: TPS3700DDCR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tps3700ddcr-etched.step / tps3700ddcr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3700ddcr.step / tps3700ddcr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tps3700ddcr.step 97 KB You want the bare part, or you mark your own boards.
tps3700ddcr-etched.step 2.2 MB You want the part with TPS3700DDCR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 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.
