LEGEND: RSVD = Reserved and must be programmed to 0
SCDDX2— Set this bit to double the SCD delay periods 0 (default) = Short Circuit current protection delay is as
programmed
1 = Short Circuit current protection delay is twice that programmed
RSNS— This bit, if set, configures the SCD threshold into a range suitable for a low sense resistor value by
dividing the SCDV selected voltage threshold by 2 0 (default) = Current protection voltage thresholds as
programmed
1 = Current protection voltage threshold divided by 2 as programmed
