TS831-4IZT

STMicroelectronics · Supervisor And Reset ICs · TO-92-3

TS831-4IZT from STMicroelectronics, in a TO-92-3. 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 OUT output Open drain reset output, active (low) when the input voltage is below the threshold, with a maximum sink current of 20mA for TS831-4 and a clamp diode to VCC (pin 2) rated at 100mA forward current.
2 IN power_in Input and supply voltage (VCC) monitored against the 4.50V typ. threshold of the TS831-4, operating range 1 to 5.5V and absolute maximum 7V.
3 GND power_in Ground, the reference terminal for all voltages.

CAD (KiCad official)

  • Symbol: TS831-4IZT
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92-3 (KiCad packages3D, STEP)
  • 3D model files: ts831-4izt-etched.step / ts831-4izt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts831-4izt.step / ts831-4izt.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (11 pp, sha256 a9b2dcc0eb416e7e, retrieved 2026-11-05, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
