The high stress staged start is recommended for application current levels below 50A, while the matched and low stress staged start configurations are recommended for applications above 50A. As compared to a single-path design, lowest MOSFET cost is afforded by the low stress staged start configuration at the expense of limited transient ride-through and not being able to start with a load current. The matched and high-stress staged start configurations start into a load and afford longer fault timers, riding through longer lasting overcurrent conditions and input voltage steps. Demo boards are available to experiment with the various configurations. With its novel dual current path feature, which can be configured in multiple ways, the LTC4282 greatly eases high current kilowatt level board designs, enabling both large SOA and low on-resistance in the same design.
