ACS755SCB-100-PSF

Current Sensor: ACS755xCB-100 5 Package CB-PFF 4 1 23 5 Package CB-PSF 4 1 23 Package CB-PSS 5 4 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 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, chopperstabilized BiCMOS Hall IC, which is programmed for accuracy at the factory. The output of the device will be valid when the current flows from pin 4 to pin 5. The internal resistance of this conductive path is typically 100 μΩ, providing low power loss. The thickness of the copper conductor allows survival of the device at up to 5× overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads (pins 1 through 3). This allows the ACS75x family of sensors to be used in applications requiring electrical isolation without the ...
