GX112S

GXCAS · Temperature and Humidity Sensor · SOT-563

GX112S from GXCAS, in a SOT-563. 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 SCL input Serial clock input for SMBus / I2C interface. Open-drain, requires an external pull-up resistor (4.7 kΩ recommended). Fast mode up to 400 kHz, high-speed mode up to 2.75 MHz.
2 GND power_in Ground reference (0 V) for the device.
3 ALERT output Over-temperature alert output. Open-drain, requires an external pull-up resistor (4.7 kΩ recommended). Polarity (active-low/high) and comparator/interrupt mode are software-configurable via POL and TM bits.
4 ADD0 input I2C slave address select. Tie to V+, GND, SCL, or SDA to select one of four possible bus addresses, allowing up to four GX112 devices on the same bus.
5 V+ power_in Positive supply voltage input, 1.4 V to 5.5 V (3.3 V nominal). Absolute maximum 6 V. Power-on reset threshold typ 1.1 V.
6 SDA bidirectional Serial data line for SMBus / I2C interface. Open-drain, requires an external pull-up resistor (4.7 kΩ recommended).

CAD (KiCad official)

  • Symbol: GX112S
  • Footprint: Package_TO_SOT_SMD:SOT-563
  • 3D model: SOT-563 (KiCad packages3D, STEP)
  • 3D model files: gx112s-etched.step / gx112s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gx112s.step / gx112s.glb are the bare package body.

Provenance

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

  • Datasheet: GXCAS datasheet (23 pp, sha256 44b38d392e1ec25d, 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).
