Shutdown Cooling Cycle (LTC4214-2)
Figure 15 shows the timer behavior of the LTC4214-2. At
time point 2, TIMER exceeds V
immediately and the LTC4214 shuts down. TIMER starts
a shutdown cooling cycle by discharging TIMER with 5 A

and three 5 A charge phases in this shutdown cooling
cycle spanning time points 2 and 3. At time point 3, the
LTC4214 automatic retry occurs with a start-up cycle.
Good thermal management techniques are highly recom-
mended; power and thermal dissipation must be carefully
evaluated when implementing the automatic retry scheme.
