• - 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
  • - Total output error improvement through gain and offset trim over temperature
  • - Small package size, with easy mounting capability
  • - Monolithic Hall IC for high reliability
  • - Ultra-low power loss: 100 μΩ internal conductor resistance
  • - Galvanic isolation allows use in economical, high-side current sensing in high voltage systems

9. Working temperature (°C): -40 to 150


The relationship between voltage output and current input:


VOUT = VOUT(Q) + Vsens x I VOUT(Q) is the quiescent output voltage, which is VCC/2, which is the output voltage when there is no input. Vsens is a sensor-sensitive scale, also known as a coefficient. I is the current flowing from IP+ to IP-.

For example, suppose the sensor model is 050B, VCC is 5V, and I current is 10A, then the output is 5V / 2+40mV/A x10A=2.9V.
