TMAG5273A1QDBVR 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; input levels are VIH min 0.7·VCC and VIL max 0.3·VCC, and the absolute maximum input voltage is -0.3 V to 7 V. |
| 2 | GND | power_in | Reference ground for the device. |
| 3 | GND (TEST) | power_in | TI test pin that must be connected to ground in the application (datasheet notes that the TEST pin should be grounded). |
| 4 | VCC | power_in | Main supply voltage with a recommended operating range of 1.7 V to 3.6 V and an absolute maximum of 4 V; place a ceramic decoupling capacitor of at least 0.01 µF close to the device. |
| 5 | INT | bidirectional | Interrupt input/output; if unused and tied to ground, set MASK_INTB = 1b. Recommended output current is 2 mA maximum, VOL max 0.4 V at 2 mA, and absolute maximum voltage is -0.3 V to 7 V. |
| 6 | SDA | bidirectional | Serial data line for the I2C interface; VOL max 0.4 V at 2 mA sink current, recommended output voltage 0 to 5.5 V, and absolute maximum voltage -0.3 V to 7 V. |
