When over-current occurs, the corresponding high side stays ON with limited current capability and the HSxCL flag is set in the HSSR ?
When open load occurs, the flag (HSxOP) is set in the HSSR ?
When short-circuit occurs and if HVSE flag is enabled, both HS automatic shutdown.
When over-temperature shutdown occurs, both high sides are turned off. All flags in HSSR are set.
When over-current occurs, the corresponding low side stays ON with limited current capability and the LSxCL flag is set in the LSSR ?
When open load occurs, the flag (LSxOP) is set in the LSSR.
When short-circuit occurs and if HVSE Flag is enabled, both LS automatic shutdown
When over-temperature shutdown occurs, both low sides are turned off. All flags in LSSR are set.
