Note 2: This device is production tested at T
Note 3: Default thresholds are set by the classification result in auto mode. The thresholds are manually software programmable
Note 4: Default value. The AC load-disconnect threshold can be programmed through the AC_TH register (R23h[2:0]).
Note 5: Default value. The load-disconnect time, t DISC can be programmed through the TDISC register (R16h[1:0]).
Note 6: R
Note 7: If Class 5 is enabled, this value is the classification current threshold from Class 4 to Class 5.
Note 8: Default values. The startup, fault, and restart timers can be programmed through the TSTART (R16h[5:4]), TFAULT
Note 9: Guaranteed by design. Not subject to production testing.
