Broadcom ACHL-7348xU Current Sensors
Broadcom ACHL-7348xU Current Sensors are fully integrated Hall-effect-based linear current sensors designed for accurate AC and DC current measurement in industrial applications. These sensors feature an isolated sensing architecture with a low-offset Hall IC and a copper conduction path that delivers precise and proportional voltage output. The ACHL-7348xU sensors support a current sensing range of up to ±80A peak and offer a typical total output error of ±1% for reliable performance. These sensors offer an internal conductor resistance of 0.7mΩ, minimizing power loss and making them suitable for high-efficiency systems. The ACHL-7348xU ICs operate from a single 5V supply and offer a typical bandwidth of 600kHz and fast overcurrent fault feedback response. These current sensors are housed in a compact SSO-12 package and comply with international isolation and safety standards. Typical applications include motor drives, industrial robots, photovoltaic inverters, and rail or phase current sensing systems.
