Broadcom ACHS-719x Series: Fully Integrated Hall-Effect Linear Current Sensor ICs

Product Overview

The Broadcom ACHS-719x series are fully integrated, Hall-effect based linear current sensors designed for AC or DC current sensing in industrial, commercial, and communications systems. These isolated sensors feature a low-offset, linear Hall circuit with an integrated copper conduction path, providing a precise voltage output proportional to the applied current. Optimized for accuracy across a wide operating temperature range, the ACHS-719x series offers a low-resistance current path (0.7 m typical) for minimal power loss. Housed in a compact, surface-mountable SO-8 package, these sensors meet worldwide regulatory safety standards, including 3 kVRMS isolation. Key applications include low-power inverter current sensing, eBikes, motor phase and rail current sensing, solar inverters, chargers, converters, and switching power supplies.
