COSINA180HA3

COSINE · Current Sense Amplifiers · SOT23-5

COSINA180HA3 from COSINE, 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 OUT output Voltage output pin; the output must stay between GND-0.3 V and VS+0.3 V, with a maximum output current of 8 mA.
2 GND power_in Analog ground reference; analog inputs are limited to GND-0.3 V to +26 V common-mode.
3 +IN input Analog input, connected to the supply side of the shunt resistor; common-mode input voltage range is +2 V to +25 V.
4 -IN input Analog input, connected to the load side of the shunt resistor; it withstands input signals up to 25 V whether or not the device has power applied.
5 VS power_in Power supply pin operating from 2.7 V to 25 V, with an absolute maximum supply voltage of 26 V.
