BL8506-27NRM 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. Asserts (pulls low) when VDD falls below the 2.7V detection threshold. Requires an external pull-up resistor (typ. 470kΩ). Max sink current 70mA; output rated -0.3V to 12V. |
| 2 | VDD | power_in | Voltage input / monitored supply pin. Operating range 0.7V to 10V; absolute maximum -0.3V to 10V. This is the supply being monitored against the 2.7V detection threshold. |
| 3 | VSS | power_in | Ground reference pin (0V). |
