Figure 11 - Start-up, Over-Current, and SOA shut-down waveforms.

The MOSFET is held off for 200us before attempting to re-

start. Again, the MOSFET will be regulated to the start-up

current level, but now turns off due to an SOA shut-down.

The True-SOA™ protection has determined that the junction

temperature of the MOSFET has risen by 60°C and has shut it

down to cool. When the SOA monitoring has determined that

the junction temperature has dropped by 39°C the MOSFET

will again turn on. The 39°C thermal cycling range will

continue for a total of 16 pulses before the range is extended

to 57°C, where the thermal cycling will go on indefinitely until

the low impedance load is removed.
