SLUSES3B October 2023 – July 2024 UCC25660
PRODUCTION DATA
The OCP and cycle-by-cycle current limiting feature in UCC25660X provides a fast (<50ns) response to short circuit.
The cycle-by-cycle protection helps to limit the peak stress in the power stage. When the ISNS voltage becomes greater than + VISNS_OCP, the current HO gate pulse is terminated. Correspondingly, during the half cycle where the LO pulse is high, if the ISNS voltage becomes less than VISNS_OCPn the current LO gate pulse is terminated.
If OCP is detected in 7 consecutive switching cycles, the device move to the fault state.
