MCS1802GS-10-Z from Monolithic Power Systems, in a SOIC-8. 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 | IP+ | passive | Primary current (+) terminal for the current being sampled; pins 1 and 2 are internally connected together. |
| 2 | IP+ | passive | Primary current (+) terminal for the current being sampled; pins 1 and 2 are internally connected together. |
| 3 | IP- | passive | Primary current (-) terminal for the current being sampled; pins 3 and 4 are internally connected together. |
| 4 | IP- | passive | Primary current (-) terminal for the current being sampled; pins 3 and 4 are internally connected together. |
| 5 | GND | power_in | Signal ground terminal. |
| 6 | FILT | passive | Filter terminal for the external capacitor CF that sets the bandwidth; it can be left floating when the bandwidth setting is not required. |
| 7 | VOUT | output | Analog output, proportional to the primary current within the specified range. |
| 8 | VCC | power_in | Voltage supply: connect to a 3.3V supply within the recommended 3.0V to 3.6V range and bypass with a 1µF low ESR ceramic capacitor as close to the VCC pin as possible. |
