H7033A-1

Shanghai Siproin Microelectronics · Supervisor And Reset ICs · SOT-89-3

H7033A-1 from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 Detector output that is Hi-Z when VDD is above VDET(+) and pulled to VSS when VDD is at or below VDET(-); sink current is at least 1.2 mA at VOUT=0.2V with VDD=2V for the 3.3V part.
2 VIN power_in Supply and voltage sensing input with operating range 1.5V to 16V and absolute maximum of -0.3V to 16V.
3 GND power_in Ground (VSS) reference pin.
