BL8506-22NRM from BL Shanghai Belling, in a SOT-23. 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 | VOUT | output | Voltage-detection output pin. N-channel open-drain, active-low: pulled low by the internal NMOS when VDD < VDET (2.2V nominal for -22 option); high-impedance otherwise (requires external pull-up resistor R0, typ 470kΩ). Max output voltage rating -0.3V to 12V, max output current 70mA. |
| 3 | VDD | power_in | Supply / sensed voltage input pin. Operating range 0.7V to 10V; absolute max -0.3V to 10V. Also the node whose voltage is compared against the internal 2.2V reference threshold. |
| 2 | VSS | power_in | Ground reference pin for the detector. Connect to system ground. |
