STM809LWX6F

STMicroelectronics · Supervisor and Reset ICs · SOT-23-3

STM809LWX6F from STMicroelectronics, in a SOT-23-3. 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 VSS power_in Device ground reference (0 V).
2 RST output Active-low, push-pull reset output. Asserted low whenever VCC falls below the reset threshold and held low for at least trec (≥140 ms) after VCC returns above the threshold. Guaranteed valid down to VCC = 1.0 V; both sources and sinks current.
3 VCC power_in Positive supply input, monitored against the internal reset threshold VRST (STM809L: 4.50-4.75 V). Recommend a 0.1 µF bypass capacitor mounted as close as possible to this pin for transient immunity.
