Dimac Red can provide three kinds of current sensors IC based on Hall effect.
Let’s talk about hall current sensor ICs!
Conventional Hall and IMC-Hall sensors measure current contactless without current-carrying circuit interruption while isolated integrated current needs to be inserted in the circuit with the current flowing inside the package as well.

So, what are the advantages of hall current sensors ICs by Melexis?
Conventional Hall sensor
Current sensors sensitive to the magnetic field perpendicular to the chip surface. A ferromagnetic core is mandatory and it is typically wrapped around the current-carrying conductor.
The core concentrates the magnetic flux on a small air gap (typically 2-5mm) where the sensor is inserted.
Features:
– Strong magnetic gain from the core
– Robust against cross-talk
– From medium to very high current
Suitable for:
– On Board charger
– HV Traction Inverter (i.e. phase current measurement)
– DC/DC converter
– Smart Fuse Overcurrent Detection
Current:
Up to 5000A
Model example:
MLX91217
Planar IMC-Hall sensors
Thanks to the use of the patented integrated magnetic concentrator (IMC), IMC-Hall® sensors are sensitive to magnetic fields parallel to the chip surface. They can directly measure the current flowing in a bus bar or a PCB trace below the package without a core.
Features:
– Easy integration and low footprint
– IMC has very high permeability and very low hysteresis
– Magnetic gain from IMC
Suitable for:
– On Board charger
– Inverter (i.e. phase current measurement)
– DC/DC converter
– Power Distribution Unit
– Battery current monitoring
Current:
Up to 2000A
Model example:
MLX91216
Isolated integrated current sensor
Combining sensing elements, signal conditioning and voltage isolation into a small footprint, it is the easiest to use all-in-one integrated current sensor.
