Specifications: The AACS773 series are high-precision, high-current integrated Hall-effect current sensors. They support 3.3V or 5V supply and offer multiple high-current measurement ranges (±50A, ±100A, ±150A, ±200A) with excellent 0.5% accuracy at 25°C. A key feature is the extremely low 0.1mΩ primary conductor resistance, minimizing power loss and thermal dissipation. They provide robust 5000Vrms galvanic isolation for safety, a fast 250kHz bandwidth, and a 1.5µs response time for dynamic current monitoring. Available in PFF, PSS, and SMT packages for through-hole or surface-mount assembly, they are designed for industrial environments with an operating temperature range of -40°C to 125°C. Application Scenarios: Ideal for high-power, precision applications. They are extensively used in motor drives and inverters for industrial automation and electric vehicles, for DC link current sensing in solar inverters and UPS systems, and for accurate power monitoring and overload protection in server power supplies and welding equipment. Their low insertion loss and high isolation make them perfect for energy-efficient, safety-critical designs.
