SOA (FPF2702)
pad size of one square inch.
During extended output-short conditions, excessive
power dissipation occurs in the load switch. FPF2700
and PFP2701 are protected by turning off the load
switch after blanking time. FPF2702 has no blanking
time feature; please refer to Note 3.
It is possible to estimate the SOA for the two FPF2702
packages, MPX and MX, through their respective SOA
curves shown in Figure 39 and Figure 40. These curves
provide a reference on how long the load switch
survives under the worst-case scenario with minimum

Note:
3.
To protect FPF2702 from an extended short condition, additional protection must be implemented in the system
to protect the device. For example, the FLAGB and PGOOD signal can be used to monitor the short-circuit fault
condition. In applications where FPF2702 can be exposed to persistent short-circuit conditions, it should be used
only with external fault management control to protect the switch.
