ACS723LLCTR-10AU-T

Allegro MicroSystems, LLC · Current Sensors · SOIC-8

ACS723LLCTR-10AU-T from Allegro MicroSystems, LLC, 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 Terminal for the current being sensed, fused internally; the primary conductor resistance is 0.65 mΩ typical.
2 IP+ passive Terminal for the current being sensed, fused internally; the primary conductor resistance is 0.65 mΩ typical.
3 IP- passive Terminal for the current being sensed, fused internally; the primary conductor resistance is 0.65 mΩ typical.
4 IP- passive Terminal for the current being sensed, fused internally; the primary conductor resistance is 0.65 mΩ typical.
5 GND power_in Signal ground terminal for the sensor IC.
6 BW_SEL input Terminal for selecting the 20 kHz or 80 kHz bandwidth; grounding it selects the 80 kHz high-bandwidth mode.
7 VIOUT output Analog output signal that is proportional to the bidirectional or unidirectional primary sensed current.
8 VCC power_in Device power supply terminal; single supply operation from 4.5 V to 5.5 V.

CAD (KiCad official)

  • Symbol: ACS723LLCTR-10AU-T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: acs723llctr-10au-t-etched.step / acs723llctr-10au-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); acs723llctr-10au-t.step / acs723llctr-10au-t.glb are the bare package body.
