Current transducer FHS 40-P/SP600
Minisens
IPM = 0 - 100 A
Introduction
The Minisens transducer is an ultra flat SMD open loop integrated circuit current transducer based on the Hall effect principle.
It is suitable for the electronic measurement of currents: DC, AC, pulsed, mixed. It has no insertion loss and provides galvanic
isolation between the primary circuit (high power) and the secondary circuit (sensor). It measures the magnetic field generated
by the current flowing in a conductor such as a PCB track. The output voltage is proportional to that magnetic field.
The IC is calibrated to minimize offset and temperature drifts. An integrated magnetic circuit gives an optimum transducer
sensitivity. High isolation between the primary circuit and transducer electronics can be obtained with a double sided PCB.
This datasheet is for a device programmed for maximum sensitivity: other options will be available. For example, the sensitivity
range will be adjustable, and a choice of fixed or ratiometric (proportional to power supply voltage) sensitivity and reference
voltage will be offered.
