HX7050A

HX(hengjiaxing) · Monitors & Reset Circuits · SOT-89

HX7050A from HX(hengjiaxing), in a SOT-89. 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 OUT output Chip output pin; with VDD at 2 V and VOUT=0.2 V it sinks at least 0.5 mA (1 mA typical), and the output voltage is limited to GND-0.3 V to VDD+0.3 V.
2 VDD power_in Chip input (supply) pin; operating voltage is 1.5 V to 12 V, with an absolute maximum rating of 15 V.
3 GND power_in Chip ground pin, the common reference for the detector.
