INA212BIRSWR from Texas Instruments, in a UQFN-10(1.4x1.8). 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	NC	unconnected	No internal connection; the pin may be left floating or connected to any voltage between V- and V+.
2	IN+	input	Shunt sense input on the power-supply side of the shunt resistor; common-mode range is -0.3 V to 26 V for version A (-0.1 V to 26 V for versions B and C), and it must be tied to pin 3 in the RSW package.
3	IN+	input	Second shunt sense input on the power-supply side of the shunt resistor, to be connected together with pin 2 (IN+).
4	IN-	input	Shunt sense input on the load side of the shunt resistor, to be connected together with pin 5 (IN-).
5	IN-	input	Second shunt sense input on the load side of the shunt resistor, to be connected together with pin 4 (IN-).
6	V+	power_in	Device supply voltage, 2.7 V to 26 V; the output swing is referenced to this supply.
7	NC	unconnected	No internal connection; the pin may be left floating or connected to any voltage between V- and V+.
8	REF	input	Reference voltage input, which may be set from 0 V to V+ to set the output level at zero differential input (must not exceed the supply voltage).
9	GND	power_in	Analog ground for the device.
10	OUT	output	Analog voltage output whose swing is limited by the V+ supply and GND rails, per the electrical characteristics.
