**JSMSEMI** · Current Sensors · SOP-8

ACS724LLCTR-30AU-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 | Current flows into the chip, positive direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms. |
| 2 | IP+ | passive | Current flows into the chip, positive direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms. |
| 3 | IP- | passive | Current flows out of the chip, negative direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms. |
| 4 | IP- | passive | Current flows out of the chip, negative direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms. |
| 5 | GND | power_in | Device ground terminal pin; reference for VCC supply and VOUT signal. |
| 6 | FILTER | passive | Bandwidth setting pin; connect an external capacitor to GND to reduce the internal low-pass filter cutoff frequency below the 250 kHz typical bandwidth. |
| 7 | VOUT | output | Analog output signal pin; ratiometric DC voltage proportional to sensed current, 66 mV/A sensitivity at VCC = 5 V for the 30 A variant. |
| 8 | VCC | power_in | Device power supply terminal pin; compatible with 3.3 V or 5 V supply, absolute maximum 6.5 V. |

## CAD (KiCad official)

- Symbol: `ACS724LLCTR-30AU-T-JSM`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `acs724llctr-30au-t-jsm-etched.step` / `acs724llctr-30au-t-jsm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `acs724llctr-30au-t-jsm.step` / `acs724llctr-30au-t-jsm.glb` are the bare package body.
