ACS723LLCTR-40AB-T

Allegro MicroSystems, LLC · Current Sensors · SOIC-8

ACS723LLCTR-40AB-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 current being sensed, fused internally with pin 2, forming the primary conductor (0.65 mΩ typ.) isolated from signal pins 5-8.
2 IP+ passive Terminal for current being sensed, fused internally with pin 1, forming the primary conductor (0.65 mΩ typ.) isolated from signal pins 5-8.
3 IP- passive Terminal for current being sensed, fused internally with pin 4; current flowing from pins 1 and 2 to pins 3 and 4 gives a positive output slope.
4 IP- passive Terminal for current being sensed, fused internally with pin 3; current flowing from pins 1 and 2 to pins 3 and 4 gives a positive output slope.
5 GND power_in Signal ground terminal.
6 BW_SEL input Selects bandwidth: tied to GND gives 80 kHz, tied to VCC gives 20 kHz for lower noise.
7 VIOUT output Analog output signal proportional to primary current, with load of at least 4.7 kΩ and up to 10 nF to GND, and a maximum rating of 25 V.
8 VCC power_in Device power supply terminal, 4.5 to 5.5 V operating range with 6 V absolute maximum, bypassed with 0.1 µF.

CAD (KiCad official)

  • Symbol: ACS723LLCTR-40AB-T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: acs723llctr-40ab-t-etched.step / acs723llctr-40ab-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); acs723llctr-40ab-t.step / acs723llctr-40ab-t.glb are the bare package body.
