Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

Resistor engineers designed to mitigate these losses must use current sensor resistors with low resistive values. This is the greatest complexity of this method, choosing the better resistor to obtain a balance between precision, energy loss, and costs in the current sensor

The use of wide-bandgap materials, such as SiC, enables higher switching speeds and higher breakdown voltages, allowing for smaller, faster, more reliable, and more efficient power devices, and that’s why it is of interest in Space applications, where the operating conditions are extreme (high temperature and high radiation levels), is growing fast.

The components are available in single-channel ATN-CNM-300S-2 and two channels ATN-CNM-300S-4; each channel has two SiC Schottky diodes in series, increasing the maximum safe blocking voltage of the device while operating under heavy ions. Actual flight radiation conditions can be tested under request as already performed successfully for the ESA-BepiColombo mission with a single die the previous version.
