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. |
