H7048A-1

Shanghai Siproin Microelectronics · Monitors & Reset Circuits · SOT-89-3

H7048A-1 from Shanghai Siproin Microelectronics, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT output Detector output that is Hi-Z when VDD is above VDET(+) and pulled to VSS when VDD is at or below VDET(-); NMOS open-drain or CMOS depending on the order suffix.
2 VIN power_in Supply and voltage-sense input, operating range 1.5V to 16V, absolute maximum -0.3V to 16V.
3 GND power_in Ground (VSS) reference pin.

CAD (KiCad official)

  • Symbol: H7048A-1
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: h7048a-1-etched.step / h7048a-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7048a-1.step / h7048a-1.glb are the bare package body.
