8.3.8.1 LIMP HOME State Exceptions

The device can receive an LHI signal during cap charging or inrush duration. If the desired state is ON, the device continues cap charging per programmed register values. If the desired state is OFF, then the channel is turned off.

In LIMP_HOME state, if a short circuit occurs that causes an overcurrent fault (ILIMIT_CHx) or a thermal shutdown fault (THERMAL_SD_CHx), the output channels continues to retry regardless of the LATCH_CHx bit setting if the channels are configured to be ON by the CHx_LH_IN bits. If LATCH_CHx = 1 and the output channels are latched off due to an overcurrent fault or thermal shutdown fault and the device enters LIMP_HOME state either through LHI = 1 or a watchdog fault (if WD_EN = 1), the channels are re-enabled and continue to retry if a persistent short exists regardless of the LATCH_CHx setting if the channels configure to be ON through the CHx_LH_IN bits.

In LIMP_HOME state, if an I2T fault (I2T_FLT_CHx) must occur on the channels and TCLDN_CHx = 00 (indefinite cooldown), the channels remains in indefinite cooldown and does not retry even if the channels are configured to be ON through the CHx_LH_IN bits. If an I2T fault occurs in active state and TCLDN_CHx = 00 (indefinite cooldown) and the device enters LIMP_HOME state either through LHI = 1 or a watchdog fault (if WD_EN = 1), the channels remains in indefinite cooldown and does not retry even if the channels configure to be ON through the CHx_LH_IN bits.
