Top Features
- Core-less, micro-sized, 100 A continuous current package
- Ultra-low power loss: 200 μΩ internal conductor resistance
- Immunity to common-mode field interference
- Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range
- Industry-leading noise performance 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
- Monolithic Hall IC for high reliability
- 3 to 3.6 V, single supply operation
- 120 kHz typical bandwidth
- 3.6 μs output rise time in response to step input current
- Output voltage proportional to AC or DC currents
- Factory-trimmed for accuracy
- Extremely stable quiescent output voltage
- AEC-Q100 automotive qualification
