HT7033S

UMW · Supervisor and Reset ICs · SOT-23

HT7033S 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. NMOS open-drain detector output that pulls low when VDD falls below VDET (typ 3.3 V for HT7033); requires an external pull-up resistor (e.g. Rp in the application circuit). Sink current IOL ≥ 2 mA (typ 4 mA) at VOUT = 0.2 V with VDD = VDET−0.2 V.
3 VDD power_in Chip input / supply. Operating range 1.5 V to 12 V (absolute max 15 V). Also serves as the sensed input for the internal voltage detector. Typical quiescent current IDD ≈ 2 µA (max 4 µA) with no load.
2 GND power_in Chip ground / 0 V reference for the supply and output driver.

CAD (KiCad official)

  • Symbol: HT7033S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht7033s-etched.step / ht7033s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7033s.step / ht7033s.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).
