INA186A1IDCKR from Texas Instruments, in a SC-70-6. 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	REF	input	Reference input. Sets the output voltage offset to enable bidirectional current sensing; drive with an external voltage (typically VS/2 for bidirectional, GND for unidirectional). Available only in DCK (SC70) and DDF (SOT-23) packages.
2	GND	power_in	Device ground / analog return.
3	VS	power_in	Power supply input, 1.7 V to 5.5 V. Bypass to GND with a 0.1 µF capacitor.
4	IN+	input	Non-inverting current-sense input. Connect to the bus-side of the shunt resistor for high-side sensing, or to the load-side for low-side sensing. Common-mode range -0.2 V to +40 V, independent of VS.
5	IN-	input	Inverting current-sense input. Connect to the load-side of the shunt resistor for high-side sensing, or to ground-side for low-side sensing.
6	OUT	output	Analog voltage output. VOUT = (VIN+ - VIN-) × Gain + VREF. Gain is 25 V/V for the INA186A1 variant.
