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.

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 recommended that this
register always be programmed to zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3001
when doing threshold comparisons and setting alarm or warning bits.

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.
