AUTOMATIC RESTART
The TPS24711/13 automatically initiates a restart after a fault has caused it to turn off the external MOSFET M
1
.
Internal control circuits use C
T
to count 16 cycles before re-enabling M
1
as shown in Figure 32 (TPS24711). This
sequence repeats if the fault persists. The timer has a 1 : 1 charge-to-discharge current ratio. For the very first
cycle, the TIMER pin starts from 0 V and rises to the upper threshold of 1.35 V and subsequently falls to 0.35 V
before restarting. For the following 16 cycles, 0.35 V is used as the lower threshold. This small duty cycle often
reduces the average short-circuit power dissipation to levels associated with normal operation and eliminates
special thermal considerations for surviving a prolonged output short.
