ALS31300EEJASR-JOY from Allegro MicroSystems, LLC, in a DFN-10-EP(3x3). 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 | Power supply input (2.65 to 3.5 V normal operation); bypass VCC to GND with a 0.1 µF capacitor. |
| 2 | ADR0 | input | I2C address select 0; connect a resistive divider to select the device address. |
| 3 | GND | power_in | Ground signal terminal. |
| 4 | INT | output | Interrupt output with 90 Ω typical on-resistance and external pull-up to VCC (10 kΩ typical). |
| 5 | NC | unconnected | Not internally connected; connect to GND. |
| 6 | ADR1 | input | I2C address select 1; connect a resistive divider to select the device address. |
| 7 | SDA | bidirectional | I2C serial data input/output, open-drain. |
| 8 | SCL | input | I2C serial clock input. |
| 9 | NC | unconnected | Not internally connected; connect to GND. |
| 10 | NC | unconnected | Not internally connected; connect to GND. |
| 11 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
