HT7022S

UMW · Supervisor and Reset ICs · SOT-23

HT7022S from UMW, 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 OUT output Chip output. Detector output driver (open-drain NMOS per functional block diagram). Sinks 1 mA (typ 2 mA) at VOUT=0.2 V when VDD is below the detection threshold VDET (2.134-2.266 V for HT7022). Requires an external pull-up to VCC.
3 VDD power_in Chip input / supply pin. Voltage sensed by the detector. Operating range 1.5 V to 12 V; absolute max 15 V. Quiescent current typ. 2 µA (max 4 µA) at VDD=3.2 V with no load.
2 GND power_in Chip ground reference (0 V).

  • HT7022SS

CAD (KiCad official)

  • Symbol: HT7022S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht7022s-etched.step / ht7022s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7022s.step / ht7022s.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (12 pp, sha256 ca4a5b03cf717e3e, 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).
