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 Bi CMOS Hall IC, which is programmed for accuracy at the factory. The output of the device will be valid when a 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 100 μΩ typical, providing low power loss. Continued on the next page… ACS755150-DS Rev. 5 Typical Application 4 IP+ 1 VCC ACS755 GND 2 IP-...
