MAX4376HAUK+T from Maxim Integrated, in a SOT-23-5. 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	OUT	output	Output voltage proportional to the magnitude of the sense voltage (VRS+ - VRS-), and approximately zero when VRS- > VRS+ (no phase reversal).
2	GND	power_in	Ground reference for the device.
3	VCC	power_in	Supply voltage, guaranteed from +3V to +28V (operating voltage range).
4	RS+	input	Power connection to the external sense resistor; common-mode input range is 0 to +28V, independent of supply voltage.
5	RS-	input	Load-side connection to the external sense resistor.
