    A Discrete Alternative to Bulky Current Transformers

    High-speed integrated sensors are the smart alternative to bulky current transformers (CTs). Low-profile SOIC packages withstand vibration and fit in small spaces where CTs cannot! 

    Features:

  • High-speed, low-latency analog output
  • Differential sensing topology
  • Small QFN, SOIC-8 and SOIC-16 footprints

    • Benefits:

  • Fast-response time and low latency for peak current tracking, and cycle-by-cycle current control 
  • Reliability in the presence of external magnetic fields
  • Increased integration in a low-profile, compact footprint

    • Applications:

    Peak current tracking, on-board Battery Chargers, power factor correction, DC-DC converters, 12V-48V servers, telecom power supplies. 

    Devices:

    ACS730, ACS732, ACS733, ACS70331

     


    Highest Ambient Temperature Ratings

    We have the broadest family of integrated current sensors with ambient temperature ratings up to 150°C! With almost twenty “L-Temp” current sensors in our growing portfolio you’re sure to find robust current sensors for all automotive and industrial needs.

    Features:

  • Integrated current sensors with the highest ambient temperature ratings (TA)

    • Benefits:

  • Reduce system cooling requirements
  • Robust sensing solution in high heat applications

    •  

     


    Non-Contact Sensing Provides Immunity to High-Voltage Transients (dv/dt) and Fast Current Spikes (di/dt)

    Patented on-chip shield circuitry reduces output errors due to high-voltage switching (high dv/dt). Additionally, the Hall-effect sensing method is immune to inductance spikes from high di/dt events, unlike most shunt plus op-amp solutions.

    Features:

  • Patented on-chip shield
  • Non-contact sensing methodology

    • Benefits:

  • Inherent immunity to current and voltage transients
  • Reduced “blank time” after switching cycle 

    • Applications

    Power factor correction, DC-DC converters, inverters, motors control, VFDs and other drives. 

    Devices:

    ACS709, ACS710, ACS711, ACS71240, ACS720, ACS724, ACS725, ACS730, ACS732, ACS733

    ​

    Fast Response Time … Zero Undershoot! 

    Features:

  • Patented signal path architecture to eliminate undershoot

    • Benefits:

  • Protect expensive IGBTs, MOSFETS and SiC-FETS by detecting in-rush currents and short circuits faster than the competition
  • Improve control with reduced response time and phase delay 

    • Applications:

    Inverters, traction inverters, integrated belt start generators (IBSG), e-Bikes, bus bar measurement, forklift and other industrial transportation.
