BL8518CB3TR263DC

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

BL8518CB3TR263DC 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 VSS power_in Ground reference pin. Tie to system 0 V / GND.
2 VOUT output Voltage-detection output, active-low CMOS push-pull (C suffix). Drives low (VSS) when VDD falls below the 2.63 V detector threshold, and returns high (equal to VDD) after Tdelay = 200 ms typical once VDD rises above the threshold. Output is undefined when VDD < VDDL (~0.5 V).
3 VDD power_in Supply voltage input and monitored rail. Recommended operating range 1.2 V to 6 V; absolute maximum 8 V. This is also the voltage being sensed against the internal 2.63 V threshold.
