TMAG5170A1QDGKR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SCK	input	SPI serial clock input. Up to 10 MHz. VIH ≥ 0.75·VCC, VIL ≤ 0.25·VCC.
2	SDI	input	SPI serial data input (MOSI). Driven by the host controller; VIH ≥ 0.75·VCC, VIL ≤ 0.25·VCC.
3	SDO	output	SPI serial data output (MISO). Push-pull output, ±2 mA drive; VOH ≥ VCC−0.4 V, VOL ≤ 0.4 V at 2 mA.
4	CS	input	SPI chip-select, active low. Frames each SPI transaction and controls the device sleep/standby wake behavior; VIH ≥ 0.75·VCC, VIL ≤ 0.25·VCC.
5	VCC	power_in	Main supply input, 2.3 V to 5.5 V. Active-mode current typ. 3.4 mA at 5.5 V; UVLO ≈ 2.1 V, OV threshold ≈ 5.9 V. Bypass close to the pin.
6	GND	power_in	Ground reference for supply and digital I/O.
7	TEST	passive	TI test pin. Must be tied to GND in the application.
8	ALERT	bidirectional	Configurable status output / trigger input, active low. Signals conversion complete, threshold-crossing interrupts, diagnostics, or acts as a wake/conversion-trigger input; open-drain style with external pull-up (e.g. 10 kΩ), VOL ≤ 0.4 V at 2 mA, tFALL ≈ 50 ns.
