However, LSSS mode has limited capability to ride through an input step or a sustained load surge in current limit. Due to the low start-up current it also cannot start up a large resistive load such as a heating element or incandescent lamp. Figure 6a shows an application circuit for a 48V, 63A system operating in the low stress staged start mode. This mode is enabled by using configuration 5 or 6 in Table 3. In this mode GATE2 drives a compact, inexpen- sive MOSFET (M2) with small SOA as a trickle charging device for start-up. GATE1 drives parallel, low RDS(ON), APPLICATIONS INFORMATION Figure 6.
