VDA0820NTA

AnaSem · Supervisor and Reset ICs · SOT-23

VDA0820NTA from AnaSem, in a SOT-23. 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 VOUT output Detector output. N-channel open-drain: pulled low (to VSS) when VIN falls below VDET (0.8V), high-impedance (requires external pull-up, typ. 100kΩ) when VIN is above VREL. Absolute max output voltage range VSS-0.3V to VIN+0.3V; max output current 50mA.
2 VSS power_in Power ground reference (0V). Common return for supply and output.
3 VIN power_in Supply and monitored input voltage. Operating range 0.7V to 6.0V; absolute max -0.3V to +7.0V. This is the voltage being monitored against the internal detection threshold (VDET=0.8V for this variant).

Ordering variants

  • VDA0820NTA

CAD (KiCad official)

  • Symbol: VDA0820NTA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: vda0820nta-etched.step / vda0820nta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); vda0820nta.step / vda0820nta.glb are the bare package body.

Provenance

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

  • Datasheet: AnaSem datasheet (None pp, sha256 4f0f97f14795b51f, 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).
