TMAG5273A1QDBVT from Texas Instruments, in a SOT-23-6. 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 | SCL | bidirectional | Serial clock for the I2C interface (IO); can also be used as an interrupt output via SCL, inputs rated -0.3 V to 7 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | GND (TEST) | power_in | TI test pin that must be connected to ground in the application. |
| 4 | VCC | power_in | Power supply, 1.7 V to 3.6 V recommended operating range. |
| 5 | INT | bidirectional | Interrupt input/output; if unused and grounded, set MASK_INTB = 1b. |
| 6 | SDA | bidirectional | Serial data for the I2C interface (IO), output voltage up to 5.5 V recommended, output current max 2 mA. |
