Register 8
Table 11. Register 8: Latched Status Indicators (Read-only, cleared on read)
BIT NAME DEFAULT DESCRIPTION
0 12AOC 0 Latches high when 12A enters over-current.
1 12AFTR 0 Latches high if 12A fast trip threshold exceeded.
2 3AOC 0 Latches high when 3A enters over-current.
3 3AFTR 0 Latches high if 3A fast trip threshold exceeded.
4 12BOC 0 Latches high when 12B enters over-current.
5 12BFTR 0 Latches high if 12B fast trip threshold exceeded.
6 3BOC 0 Latches high when 3B enters over-current.
7 3BFTR 0 Latches high if 3B fast trip threshold exceeded.
12AOC This bit is set if the voltage on the PASSA pin drops below the timer start threshold, signifying a current
limit condition. This bit remains set until Register 8 is read.
12AFTR This bit is set if the voltage across the sense resistor for channel 12A exceeds the fast trip threshold.
This bit remains set until Register 8 is read.
3AOC This bit is set if the gate-to-source voltage on the channel 3A pass FET drops low enough to start the fault
timer. This bit remains set until Register 8 is read.
3AFTR This bit is set if the current through channel 3A exceeds the fast trip threshold. This bit remains set until
Register 8 is read.
12BOC This bit is set if the voltage on the PASSB pin drops below the timer start threshold, signifying a current
limit condition. This bit remains set until Register 8 is read.
12BFTR This bit is set if the voltage across the sense resistor for channel 12B exceeds the fast trip threshold.
This bit remains set until Register 8 is read.
3BOC This bit is set if the gate-to-source voltage on the channel 3B pass FET drops low enough to start the fault
timer. This bit remains set until Register 8 is read.
3BFTR This bit is set if the current through channel 3B exceeds the fast trip threshold. This bit remains set until
Register 8 is read.
