BL8506-33CRM

BL Shanghai Belling · Supervisor And Reset ICs · SOT-23

BL8506-33CRM from BL Shanghai Belling, in a SOT-23. 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 VOUT output Voltage detection output (CMOS, active low for the C type) that goes to GND level when VDD drops below -VDET (3.3V typ. for the -33 version), with absolute maximum output voltage of -0.3V to 12V and maximum output current of 70mA.
2 VSS power_in Ground pin.
3 VDD power_in Voltage input and supply pin, with recommended operating range of 0.7V to 10V and absolute maximum input voltage of -0.3V to 10V.
