STM6822TWY6F

STMicroelectronics · Supervisor And Reset ICs · SOT-23-5L

STM6822TWY6F from STMicroelectronics, in a SOT-23-5L. 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 RST output Active low, open drain reset output; asserted (pulled low) when VCC falls below reset threshold (3.000-3.150 V for T-grade), MR is driven low, or watchdog timeout occurs; remains low for trec (140-280 ms typical); requires external pull-up resistor to any supply up to 6 V.
2 VSS power_in Ground; power supply return (0 V reference).
3 MR input Manual reset input (active low); internal 52 kΩ pull-up resistor; asserts reset when driven low; provides 100 ns glitch immunity; can be left open if unused or tied to VCC.
4 WDI input Watchdog timer input; triggers reset assertion if signal remains high or low for ≥1.6 s (typical); cleared by toggling (minimum 50 ns pulse width at VCC ≥ 3.0 V) or by reset assertion; can be disabled by leaving unconnected (max 10 µA leakage).
5 VCC power_in Positive supply voltage input; operating range 1.0 to 5.5 V; guaranteed reset assertion down to VCC = 1.0 V.
