CSA220MASOT235 from analogysemi, in a SOT23-5. 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 GND power_in Power ground pin and reference for the supply bypass capacitor; absolute voltage range on the RS+ and RS- inputs is referenced to GND, and VDD to GND is rated -0.3 V to 6.0 V.
2 OUT output Sense amplifier output; Table 8 gives VOL of 10 mV with 500 µA sink and VOH of VDD - 0.01 V with 500 µA source, and capacitive load is limited to 500 pF without an isolation resistor.
3 VDD power_in Supply voltage input, recommended 2.7 V to 5.5 V (absolute maximum -0.3 V to 6.0 V), with at least a 100 nF capacitor connected to GND.
4 RS- input External sense-resistor load-side connection; absolute input voltage is limited to GND to 76 V and continuous input current to ±20 mA.
5 RS+ input External sense-resistor power-side connection; absolute input voltage is limited to GND to 76 V, and RS+ to RS- is rated ±80 V for 1 s maximum due to package thermal dissipation.
