KIA7033AT-RTK

KEC Semicon · Supervisor And Reset ICs · SOT-23-3L

KIA7033AT-RTK from KEC Semicon, in a SOT-23-3L. 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 VCC power_in Supply voltage input, rated -0.3 to +15.0 V absolute maximum, with the electrical characteristics specified at VCC=5V.
2 OUT output Open-collector reset output that goes low (VOL 0.4V max, IOL 20mA min) when VCC falls below the detecting voltage, with 0.1µA max leakage at VCC=15V when high.
3 GND power_in Ground (VEE) reference for the supply and reset output.
