ACS724LLCTR-20AU-T-JSM from JSMSEMI, in a SOP-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 conductor input, positive direction; internally connected to pin 2; current flows into the chip through this path; primary conductor resistance 0.85 mΩ typical. |
| 2 | IP+ | passive | Primary current conductor input, positive direction; internally connected to pin 1; current flows into the chip through this path; primary conductor resistance 0.85 mΩ typical. |
| 3 | IP- | passive | Primary current conductor output, negative direction; internally connected to pin 4; current flows out of the chip; galvanically isolated from signal-side pins. |
| 4 | IP- | passive | Primary current conductor output, negative direction; internally connected to pin 3; current flows out of the chip; galvanically isolated from signal-side pins. |
| 5 | GND | power_in | Device ground terminal; signal-side reference ground for VCC supply and analog output. |
| 6 | FILTER | passive | Bandwidth setting pin; an external capacitor from this pin to GND sets the output low-pass filter cutoff frequency (typical application uses 1 nF giving ~250 kHz bandwidth). |
| 7 | VOUT | output | Analog output voltage proportional to sensed primary current; sensitivity 100 mV/A at VCC=5V for the 20A unipolar range; quiescent output voltage ≈ 0.5 V (VCC×0.1) at zero current; output voltage range 0.3 V to VCC−0.1 V. |
| 8 | VCC | power_in | Device power supply terminal; operating range 4.5 V to 5.5 V (5V nominal for ACS724); maximum supply current 15 mA no-load; compatible with 5V power supply. |
