ZXCT1051E5TA from Diodes Incorporated, in a SOT-23-5. 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	VCC	power_in	Analog supply providing power to internal circuitry. Operating range 2.7V to 20V (absolute max 20V).
2	GND	power_in	Ground / 0V reference for the device.
3	VOUT	output	Analog output voltage pin. Delivers VSENSE × 10 (fixed gain of 10) over an output range of 0V to VCC-2V. Output impedance ~3.75kΩ typical.
4	VSENSE+	input	Positive current-sense input; connects to the high side of the external sense resistor. Common-mode input range 0V up to VCC.
5	VSENSE-	input	Negative current-sense input; connects to the low side of the external sense resistor. Common-mode input range 0V up to VCC-2V. Pin current varies with differential sense voltage (typ 60nA at VSENSE=0).
