STMicroelectronics · Supervisor And Reset ICs · SOT-23-5
STM6822LWY6F from STMicroelectronics, in a SOT-23-5. 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 for the STM6822: it pulses low when triggered, stays low while VCC is below the reset threshold or MR is low, and needs a pull-up resistor to a supply of up to 6 V. |
| 2 | VSS | power_in | Ground reference pin for the supervisor. |
| 3 | MR | input | Active low push-button reset input with an internal 52 kΩ pull-up (35 to 75 kΩ); a logic low asserts reset, which stays asserted for trec after MR returns high, and it can be left open if unused. |
| 4 | WDI | input | Watchdog input: if WDI is not toggled within the 1.6 s (typ.) watchdog timeout period, reset is asserted, and it may be left floating or driven by a tristate buffer to disable the watchdog. |
| 5 | VCC | power_in | Supply voltage monitored for reset; operating range is 1.2 V to 5.5 V and the absolute maximum rating is -0.3 to 7.0 V. |
