1 / 41 page  Application 1: the ACS772 outputs an analog signal, VOUT, that varies linearly with the bidirectional AC or DC primary sensed cur- rent, IP, within the range specified. RF and CF are for optimal noise management, with values that depend on the application. ACS772 The Allegro™ ACS772 family of current sensor ICs provide economicalandprecisesolutionsforACorDCcurrentsensing, idealformotorcontrol,loaddetectionandmanagement,power supply and DC-to-DC converter control, and inverter control. The 2.5 µs response time enables overcurrent fault detection in safety-critical applications. The device consists of a precision, low-offset linear Hall circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportionalvoltage.Deviceaccuracyisoptimizedthroughthe close proximity of the magnetic signal to the Hall transducer. A precise, proportional output voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory. Proprietary digital temperature compensation technology greatly improves the IC accuracy and temperature stability. High-level immunity to current conductor dV/dt and stray electricfieldsisofferedbyAllegroproprietaryintegratedshield technology for low output voltage ripple and low offset drift in high-side, high-voltage applications. The output of the device increases when an increasing current flows through the primary copper conduction path (from terminal 4 to terminal 5), which is the path used for current sampling. The internal resistance of this conductive path is 100 μΩ typical, providing low power loss. The thickness of the copper conductor allows survival of the device at high overcurrent conditions. The terminals of the conductive path are electrically isolated from the signal leads (pins1through3).ThisallowstheACS772familyofsensorICs to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.
