CC6903SO-30A from Cross chip, in a SOP-8. 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 | IP+ | input | Primary positive terminal of current sampling path for -30A to +30A input with 1.5-1.8mΩ series resistance. |
| 2 | IP+ | input | Parallel positive terminal of current sampling path internally connected to pin 1 for low-impedance current input. |
| 3 | IP- | input | Primary negative terminal of current sampling path for -30A to +30A input with 1.5-1.8mΩ series resistance. |
| 4 | IP- | input | Parallel negative terminal of current sampling path internally connected to pin 3 for low-impedance current return. |
| 5 | GND | power_in | Ground reference providing negative supply rail and analog circuit reference potential. |
| 6 | NC | unconnected | No connection pin that must be left floating and not connected to any circuit. |
| 7 | OUT | output | Analog voltage output ranging from 0.33V to 2.97V proportional to input current from -30A to +30A at 44mV/A sensitivity. |
| 8 | VCC | power_in | Positive supply voltage requiring 3.0V to 3.6V nominal with 0.1µF bypass capacitor to ground. |
