TMAG5273A2QDBVT 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; the recommended input levels are VIH of 0.7 VCC minimum and VIL of 0.3 VCC maximum, with an absolute maximum input voltage of 7 V. |
| 2 | GND | power_in | Reference ground for the device. |
| 3 | GND (TEST) | power_in | TI test pin that the datasheet says must be connected to the ground of the application (the datasheet also says to tie it to ground in the power-supply recommendations). |
| 4 | VCC | power_in | Main supply pin, recommended operating range 1.7 V to 3.6 V with an absolute maximum of -0.3 V to 4 V; supply ramp rate should be at least 3 V/ms (datasheet recommendation) and a local decoupling capacitor of at least 0.01 µF should be placed close to the device. |
| 5 | INT | bidirectional | Interrupt input/output; if unused and tied to GND, set MASK_INTB = 1b, with output voltage up to 5.5 V recommended (7 V absolute maximum) and output current of 2 mA recommended (10 mA absolute maximum), and VOL of 0.4 V maximum at 2 mA. |
| 6 | SDA | bidirectional | Serial data line for the I2C interface; output voltage up to 5.5 V recommended (7 V absolute maximum), output current of 2 mA recommended (10 mA absolute maximum), and VOL of 0.4 V maximum at 2 mA. |
