STM6315SDW13F

STMicroelectronics · Monitors & Reset Circuits · SOT-143-4

STM6315SDW13F 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 pin of the device.
2 RST output Active-low open drain reset output that requires an external pull-up resistor to any supply up to 6V and is guaranteed valid down to VCC = 1.0V.
3 MR input Manual reset input where a logic low asserts RST, with an internal 63kΩ (typ) pull-up so it may be left open if unused.
4 VCC power_in Supply voltage input with an operating range of 1.0 to 5.5V.
