D[6]
D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mA)
Serial Address
A2h = 1010001b
Byte Address
16 = 10h
This register is to be used in conjunction with IMAXl to yield a sixteen-bit value. The value in this register is
uncalibrated. The value in IMAXh is compared against ILDh. Alarm bit Ax is set if ILDh > IMAXh.
Bias Current High Alarm Threshold LSB (IMAXl)
D[7]
D[6]
D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mA)
Serial Address
A2h = 1010001b
Byte Address
17 = 11h
Each LSB represents 2
A. This register is to be used in conjunction with IMAXh to yield a sixteen-bit value. The value
in this register is uncalibrated. The value in IMAXh is compared against ILDh. Alarm bit Ax is set if ILDh > IMAXh.
Since ILDl is always zero, it is recommended that this register always be programmed to zero. This register is provided
for compliance with SFF-8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or
warning bits.
Bias Current Low Alarm Threshold MSB (IMINh)
D[7]
D[6]

read/write
Default Value
0000 0000b = 00h (0mA)
Serial Address
A2h = 1010001b
Byte Address
18 = 12h
This register is to be used in conjunction with IMINl to yield a sixteen-bit value. The value in this register is
uncalibrated. The value in IMINh is compared against ILDh. Alarm bit Ax is set if ILDh < IMINh.
Bias Current Low Alarm Threshold LSB (IMINl)

read/write
Default Value
0000 0000b = 00h (0mA)
Serial Address
A2h = 1010001b
Byte Address
19 = 13h
Each LSB represents 2
A. This register is to be used in conjunction with IMINh to yield a sixteen-bit value. The value
in this register is uncalibrated. The value in IMINh is compared against ILDh. Alarm bit Ax is set if ILDh < IMINh. Since
ILDl is always zero, it is recommended that this register always be programmed to zero. This register is provided for
compliance with SFF-8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or
warning bits.
