48 V Resettable eFuse

Selected

Top View

With the arrival of 48 V systems, a new method of safely connecting and disconnecting high current loads to the battery is required. This results in problems associated with arcing, which occurs when using mechanical relays.

Therefore, an electronic fuse (eFuse) has been designed to switch loads up to 200 A at 48 V on a compact double-sided FR4 printed circuit board with passive cooling.
