BL8506-30NRM 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. N-channel open-drain, active-low: pulled low when VDD falls below -VDET (typ. 3.0V for the -30 option); released (Hi-Z) above +VDET = -VDET + VHYS. Requires an external pull-up resistor (typ. 470kΩ) to VDD or another rail. Output rated to 12V max, 70mA max sink; propagation delay TPLH ≤ 20µs. |
| 2 | VSS | power_in | Ground reference pin (0V). |
| 3 | VDD | power_in | Supply and monitored input voltage. Recommended operating range 0.7V-10V (absolute max 10V, min VDDL ≈ 0.5V). The internal comparator senses VDD against the trimmed reference to generate the detection output. |
