5) Reg06 ID1
Register 05 is the IC information indicating
register. The highest four bits, vendor ID D[7:4],
are set to 1000 internally.
The lowest four bits, IC Revision ID D[3:0],
indicates IC revision information.
NAME

DESCRIPTION
Vendor ID
D[7:4]
1000.
IC Revision ID
D[3:0]
IC revision.
7) Reg06 Status
Register 06 is a fault condition indicating
register. The highest four bits, D[7:4], are
reserved for future use.
The bit OC is the output over-current indication.
When the bit is set to 1, the IC is in hiccup
mode or OC latch-off.
The bit OTEW is the die temperature early
warning indication. When the bit is set to 1, the
IC die temperature is higher than 120°C.
The bit PG is output power good indication.
When the bit is set to 1, the output power is
normal.

DESCRIPTION
Reserved
D[7:4]
Reserved for future use.
OC
D[3]
Output over-current indication. When this bit is high, the IC is in hiccup mode or trips
OC latch off.
OTEW
D[2]
Die temperature early warning bit. When the bit is high, the die temperature is higher
than 120˚C.
OT
D[1]
Over-temperature indication. When the bit is high the IC is in thermal shutdown
PG
D[0]
Output power good indication. When the bit is high the VOUT power is normal. This
means VOUT is higher than 95% and lower than 115% of the designed regulation
voltage. PG compares FB/VOUT with REF.
