PRODUCTION DATA
In steady state operation, the device offers immediate shutdown overcurrent protection (IOCP) which is an overcurrent protection function that immediately turns off the channel if the output current exceeds the IOCP threshold that is set by the ILIMIT_SET_CHx [3:0] bits. The ILIMIT_SET_CHx [3:0] bits enable the IOCP function to be set on a per channel basis. The IOCP function can not be disabled and is always active in the steady state operation while the device is enabled.
If the IOCP level is exceeded, the channel will turn off immediately and the channel will either retry or latch-off based on the setting of the LATCH_CHx bit. If LATCH_CHx = 0, the device will retry after tRETRY. If After the retry time expires, the device will start up into the inrush period if configured. If LATCH_CHx = 1 and the IOCP level is exceeded, the device will latch-off and will not retry until the CHx_ON bit (version A) is toggled or the DIx pin (version B) is toggled or the LATCH_CHx bit is toggled. For more details on how the retry and latch off works for different device settings, see the retry and latch-off behavior section below.
