CS30CL from STMicroelectronics, in a SOT-23-5L. 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 is proportional to the magnitude of the sense voltage Vp-Vm and is buffered, with Vout limited to the range -0.3 V to VCC.
2	Gnd	power_in	Ground line, the voltage reference for all pin voltages (absolute maximum ratings are referenced to this pin).
3	Vp	input	Connection for the external sense resistor on the side where the measured current enters the shunt; input voltages must stay within -0.3 V to 60 V with respect to Gnd.
4	Vm	input	Connection for the external sense resistor on the side where the measured current exits the shunt; input voltages must stay within -0.3 V to 60 V with respect to Gnd.
5	VCC	power_in	Positive power supply line, operating from 4.0 V to 24 V (absolute maximum -0.3 V to 25 V).
