HX3144ESO from HUAXIN, 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 | VDD | power_in | Supply input, 2.5 V to 24 V (absolute max -28 to 28 V). Includes reverse-bias protection; typical supply current 2.5 mA at VDD = 5 V, B < Bop. |
| 2 | OUTPUT | output | Open-collector digital output. When magnetic field exceeds Bop (typ. 60 G, max 100 G) the output turns on (Vsat <= 400 mV at Iout = 20 mA). Sink capability up to 50 mA; leakage <= 10 uA at Vout = 20 V. Recommended pull-up R1 = 1 kOhm. |
| 3 | GND | power_in | Ground reference for the device. |
