ACS756xCB Fully Integrated, Hall Effect-Based Linear Current Sensor IC with Voltage Isolation and a Low-Resistance Current Conductor Not for New Design These parts are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available.

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 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 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 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 typical, providing low power loss. The thickness of the copper conductor allows survival of the device at up to 5x overcurrent conditions.
