| ACS754xCB-100 Fully Integrated, Hall Effect-Based Linear Current Sensor with High Voltage Isolation and a Low-Resistance Current Conductor Monolithic Hall IC for high reliability Single +5 V supply 3 kVRMS isolation voltage between terminals 4/5 and pins 1/2/3 for up to 1 minute 35 kHz bandwidth Automotive temperature range End-of-line factory-trimmed for gain and offset Ultra-low power loss 100 uΩ internal conductor resistance Ratiometric output from supply voltage Extremely stable output offset voltage Small package size, with easy mounting capability Output proportional to AC and DC currents Package 5 pin module leadform PFF The Allegro ACS75x family of current sensors provides economical and precise solutions for current sensing in industrial, automotive, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, power supplies, and overcurrent fault protection. The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory. The output of the device has a positive slope >VCC / 2 when an increasing current flows through the primary copper conduction path from terminal 4 to terminal 5 , which is the path used for current sensing. The internal resistance of this conductive path is typically 100 uΩ, providing low power loss. The thickness of the copper conductor allows survival of the device at up to Continued on the next 4 IP+ 1 VCC ACS754 GND 2 VIOUT CBYP µF CF RF VOUT Application The ACS754 outputs an analog signal, VOUT that varies linearly with the uni- or bi-directional AC or DC primary sensed current, IP , within the range specified. CF is recommended for noise management, with values that depend on the application. ACS754xCB-100 Fully Integrated, Hall Effect-Based Linear Current Sensor with High Voltage Isolation and a Low-Resistance Current Conductor Description continued 5x overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads pins 1 through This allows the ACS75x family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques. The device is fully calibrated prior to shipment from the factory. The ACS75x family is lead Pb free. All pins are coated with 100% matte tin, and there is no lead inside the package. The heavy gauge leadframe is made of oxygen-free copper.
