Application information
Jumper
The use of a jumper and PCB tracks to realize a complete loop around Minisens allows it to have a very high sensitivity for a
nominal current of about 10 Amps
Creepage, clearance
Nominal primary current I
(85°C ambient, natural convection,
30°C track temperature rise)
Measuring range I
Sensitivity G
Track width under IC
Track width elsewhere
A demo board of this
design is available
PCB characteristics 1.6 mm / 70 µm Cu.
Cable or busbar
For very large currents (>50A), Minisens can be used to measure the current flowing in a cable or busbar.
The position of Minisens relatively to the conductor has to be stable to avoid sensitivity variations.
