DESCRIPTION
SUP_FLT
7R
Interrupt signal for supply faults. SUP_FLT is the logic OR of all the bits [7:0] in register R0Ah/R0Bh
(Table 8).
TSTR_FLT
6R
Interrupt signal for startup failures. TSRT_FLT is the logic OR of bits [7:0] in register R08h/R09h
(Table 7).
IMAX_FLT
5R
Interrupt signal for current-limit violations. IMAX_FLT is the logic OR of bits [3:0] in register
R06h/R07h (Table 6).
CL_END
4R
Interrupt signal for completion of classification. CL_END is the logic OR of bits [7:4] in register
R04h/R05h (Table 5)
DET_END
3R
Interrupt signal for completion of detection. DET_END is the logic OR of bits [3:0] in register
R04h/R05h (Table 5).
LD_DISC
2R
Interrupt signal for load disconnection. LD_DISC is the logic OR of bits [7:4] in register R06h/R07h
(Table 6).
PG_INT
1
R
Interrupt signal for PGOOD status change. PG_INT is the logic OR of bits [7:4] in register R02h/R03h
(Table 4).
PE_INT
0
R
Interrupt signal for power-enable status change. PEN_INT is the logic OR of bits [3:0] in register
R02h/R03h (Table 4).

interrupts.
MASK3
3
R/W
Interrupt mask bit 3. A logic high enables the DET_END interrupts. A logic low disables the
DET_END interrupts.
MASK2
2
R/W
Interrupt mask bit 2. A logic high enables the LD_DISC interrupts. A logic low disables the LD_DISC
interrupts.
MASK1
1
R/W
Interrupt mask bit 1. A logic high enables the PG_INT interrupts. A logic low disables the PG_INT
interrupts.
MASK0
