BL Shanghai Belling · Supervisor and Reset ICs · SOT-89-3
BL8506-48CSM from BL Shanghai Belling, in a SOT-89-3. 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. CMOS push-pull output, active LOW: asserts low when VDD falls below the detection threshold (-VDET = 4.8V typ. for the -48 variant). Typical hysteresis 4%. Output delay ≤20µs. |
| 2 | VDD | power_in | Voltage input pin / monitored supply. Recommended operating range 0.7V to 10V (absolute max -0.3V to 10V). This is also the rail whose voltage is compared against the internal -VDET threshold. |
| 3 | VSS | power_in | Ground reference pin (0V) for the detector. |
