200kHz, High-Accuracy Current Sensor IC with 100µΩ Conductor and 3.3V Operation

• AEC-Q100 Grade 1 qualified
• Typical of 2.5 μs output response time
• 3.3 V supply operation
• Ultra-low power loss: 100 μΩ internal conductor resistance
• Reinforced galvanic isolation allows use in economical, high-side current sensing in high-voltage systems
• 4800 Vrms dielectric strength certified under UL60950-1
• Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
• Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high-voltage applications
• Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range
• Small package size, with easy mounting capability
• Monolithic Hall IC for high reliability
• Output voltage proportional to AC or DC currents
• Factory-trimmed for accuracy
• Extremely stable output offset voltage
• Available in ratiometric and non-ratiometric versions
