ith the arrival of 48V systems, a new method of
safely connecting and disconnecting high current
loads –such as electric power steering, electric
turbocharger, etc.–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 200A at 48V on a
compact double-sided FR4 printed circuit board with passive
cooling (Figure 1).
