Insulation design enables economical high-end current sensing in high voltage systems
Meets AEC Q-100 standards
3.0 to 5.5V, single supply operation
120 kHz typical bandwidth
Corresponding to the step input current, the output rise time is 3 μs
Output voltage is proportional to AC or DC current
Calibrated at the factory to ensure accuracy
Extremely stable output offset voltage
Near zero hysteresis
The relationship between voltage output and current input:
VOUT = VOUT(Q) + Vsens x I
VOUT(Q) is the static 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 x 10A = 2.9V.
