AUTO-RETRY FUNCTIONALITY
Some applications require that an overcurrent condition disables the part momentarily during a fault condition
and re-enables after a pre-set time. This auto-retry functionality can be implemented with an external resistor and
capacitor. During a fault condition, FAULTx pulls ENx low disabling the part. The part is disabled when ENx is
pulled below the turn-off threshold, and FAULTx goes high impedance allowing CRETRY to begin charging. The
part re-enables when the voltage on ENx reaches the turn-on threshold, and the auto-retry time is determined by
the resistor/capacitor time constant. The part will continue to cycle in this manner until the fault condition is
removed.
Figure 19. Auto-Retry Functionality
Some applications require auto-retry functionality and the ability to enable/disable with an external logic signal.
The figure below shows how an external logic signal can drive EN through RFAULT and maintain auto-retry
functionality. The resistor/capacitor time constant determines the auto-retry time-out period.
