Description
Bit 0 (LSB)
ISET
1
Current limit of LNB output (VOUT pin) set to lower current
range
(see Section 2.6: "Output current limit selection")
0
Current limit of LNB output (VOUT pin) set to default range
(see Section 2.6: "Output current limit selection")
Bit 1
ISW
1
DC-DC, inductor switching current limit set to 2.5 A typ.
0
DC-DC, inductor switching current limit set to 4 A typ.
Bit 2
PCL
1
Pulsed (dynamic) LNB output current limiting is deactivated
0
Pulsed (dynamic) LNB output current limiting is active
Bit 3
TIMER
1
Pulsed (dynamic) LNB output current TON time set to 180 ms
typ.

Bit 0 (LSB)
EN_IMON
1
IMON diagnostic function is enabled. (VOUT is set to 21
V typ.)

Bit 3
OLR
1
In case of overload protection activation (OLF=1), all
VSEL 1..4 bits are reset to “0” and LNB output (VOUT
pin) is disabled. VSEL bits have to be set again by the
master after the overcurrent condition is removed
(OLF=0)
0
In case of overload protection activation (OLF=1) the
LNB output (VOUT pin) is automatically enabled as
soon as the overload condition is removed (OLF=0)
with the previous VSEL bits setting
