Automatic Restart (Figure 16)
The TPS2481 automatically initiates a restart after a fault has caused it to turn off the external FET. Internal
control circuits use CT to count 16 cycles before re-enabling the external FET. This sequence repeats if the fault
persists. The TIMER has a 1:10 charge-to-discharge current ratio, and uses a 1-V lower threshold. The fault-retry
duty cycle specification quantifies this behavior. This small duty cycle often reduces the average short-circuit
power dissipation to levels associated with normal operation and reduces the need for additional protection
devices.
