A31010SEHALT-10 from Allegro MicroSystems LLC, in a DFN-6(2x3). 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 pin for the sensor, specified at 2.5 V to 3.5 V (3.0 V typical), with a 7 V absolute maximum supply voltage. |
| 2 | OUT | output | Unidirectional analog output that is proportional to the applied magnetic field; the output voltage must not exceed VCC + 0.1 V, and the output needs a resistive load of at least 15 kΩ and a capacitive load of at most 10 nF. |
| 3 | GND | power_in | Ground reference; all device ratings are referenced to this pin. |
| 4 | GND | power_in | Ground reference; all device ratings are referenced to this pin. |
| 5 | SLEEP | input | Active-low sleep control: pulling it below VSL (0.2 × VCC) enters sleep mode, driving it above VSH (0.45 × VCC) returns the device to active mode, and the input range is −0.1 V to VCC + 0.5 V. |
| 6 | VREF | power_in | Supply input for the ratiometric reference, which must be between 2.5 V and VCC, with a 7 V absolute maximum rating. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
