Application information
Multi-turns
For low currents (under 10 A), it is advisable to make several turns with the primary track to increase the magnetic field
generated by the primary current.
As with a single track, it is better to have wider tracks around the Minisens than under it (to reduce temperature rise)
Two optimized design examples are presented below.
