read/write
Default Value
0000 0000b = 00h (0V)
Serial Address
A2h = 1010001b
Byte Address
08 = 08h
Each LSB represents 25.6mV. This register is to be used in conjunction with VMAXl to yield a sixteen-bit value. The
value in TMINh is compared against VINh. Alarm bit Ax is set if VINh > VMAXh.

read/write
Default Value
0000 0000b = 00h (0V)
Serial Address
A2h = 1010001b
Byte Address
09 = 09h
Each LSB represents 100
V. This register is to be used in conjunction with VINh to yield a sixteen-bit value. The value
in VMAXh is compared against VINh. Alarm bit Ax is set if VINh > VMAXh. Since VINl is always zero, it is recom-
mended 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.

Serial Address
A2h = 1010001b
Byte Address
10 = 0Ah
Each LSB represents 25.6mV. This register is to be used in conjunction with VMINl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in VMINh is compared against VINh. Alarm bit Ax is set if VINh<VMINh.

Serial Address
A2h = 1010001b
Byte Address
11 = 0Bh
Each LSB represents 100
V. This register is to be used in conjunction with VINh to yield a sixteen-bit value. The value
in VMINh is compared against VINh. Alarm bit Ax is set if VINh < VMINh. Since VINl 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.
