STM812SW16F

STMicroelectronics · Supervisor And Reset ICs · SOT-143-4

STM812SW16F from STMicroelectronics, in a SOT-143-4. 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 VSS power_in Ground reference for the device.
2 RST output Active-high push-pull reset output on the STM812, asserted when VCC falls below the reset threshold or MR is low, and held for trec (140 ms min) afterwards; valid down to VCC = 1.0 V (0 to 70 °C).
3 MR input Active-low manual reset input with internal 20 kΩ pull-up (10 to 30 kΩ), which can be left open if unused; a low level of at least 10 µs asserts reset.
4 VCC power_in Supply voltage input, operating range 1.0 to 5.5 V (1.2 V to 5.5 V over -40 to 85 °C), absolute maximum 7.0 V.

  • Symbol: STM812SW16F
  • Footprint: Package_TO_SOT_SMD:SOT-143
  • 3D model: SOT-143-4 (KiCad packages3D, STEP)
  • 3D model files: stm812sw16f-etched.step / stm812sw16f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stm812sw16f.step / stm812sw16f.glb are the bare package body.

Provenance

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