HX6639IUA-D
HUAXIN · Linear Hall Sensors · TO-92S
HX6639IUA-D from HUAXIN, in a TO-92S. 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 | VDD | power_in | Supply input; the supply must be greater than the minimum operating voltage of 2.8 V (operating range 2.8 V to 6.0 V). |
| 2 | GND | power_in | Ground pin that must be strongly connected to the ground of the power supply. |
| 3 | OUTPUT | output | Push-pull analog output that needs no pull-up resistor; it sits at VDD/2 with no applied field, rises above VDD/2 for an S-pole field and falls below VDD/2 for an N-pole field, with updates occurring after Tsw. |
