Introduction

AI Translation

The ACS724 outputs an analog signal, v_IOUT, that changes proportionally with the bidirectional AC or DC primary sensed current, l_P, within the specified measurement range. The FILTER pin can be used to decrease the bandwidth in order to optimize the noise performance. The ACS724 is provided in a small, low-profile surface-mount SOIC8 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb-based solder balls, currently exempt from RoHS. The device is fully calibrated prior to shipment from the factory.

Features

AI Translation
  • Differential Hall sensing rejects common-mode fields
  • 1.2 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
  • Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
  • Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
  • High-bandwidth 120 kHz analog output for faster response times in control applications
  • Filter pin allows user to filter the output for improved resolution at lower bandwidth
  • Patented integrated digital temperature compensation circuitry allows for near closed loop accuracy over temperature in an open loop sensor
  • Small-footprint, low-profile SOIC8 package suitable for space-constrained applications
  • Filter pin simplifies bandwidth limiting for better resolution at lower frequencies
  • 5 V, single supply operation
  • Output voltage proportional to AC or DC current
  • Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
  • Chopper stabilization results in extremely stable quiescent output voltage
  • Nearly zero magnetic hysteresis
  • Ratiometric output from supply voltage

Applications

AI Translation
  • motor control
  • load detection and management
  • switched-mode power supplies
  • overcurrent fault protection
