Product Overview
The Broadcom ACHS-719x series are fully integrated, Hall-effect based linear current sensors designed for accurate AC or DC current sensing in industrial, commercial, and communications systems. These isolated sensors feature a low-offset, linear Hall circuit with a low-resistance copper conduction path (0.7 m typical) for minimal power loss. The device provides a precise, proportional voltage output that is ratiometric to the supply voltage, with factory-programmed accuracy and stable output offset. Optimized for device accuracy across operating temperatures, the ACHS-719x series offers a wide operating temperature range (40C to +110C) and is housed in a compact, surface-mountable SO-8 package. Key applications include low-power inverter current sensing, eBikes, motor phase and rail current sensing, solar inverters, chargers and converters, and switching power supplies.
