read/write
Default Value
0000 0000b = 00h (0V)
Serial Address
A2h = 1010001b
Byte Address
12 = 0Ch
Each LSB represents 25.6mV. This register is to be used in conjunction with VHIGHl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in VHIGHh is compared against VINh. Warning bit Wx is set if VINh >
VHIGHh.

read/write
Default Value
0000 0000b = 00h (0V)
Serial Address
A2h = 1010001b
Byte Address
13 = 0Dh
Each LSB represents 100
V. This register is to be used in conjunction with VHIGHh to yield a sixteen-bit value. The
value in VHIGHh is compared against VINh. Warning bit Wx is set if VINh > VHIGHh. 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.

Serial Address
A2h = 1010001b
Byte Address
14 = 0Eh
Each LSB represents 25.6mV. This register is to be used in conjunction with VLOWl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in VLOWh is compared against VINh. Warning bit Wx is set if VINh <
VLOWhh.

Serial Address

Byte Address
15 = 0Fh
Each LSB represents 100
V. This register is to be used in conjunction with VLOWh to yield a sixteen-bit value. The
value in VLOWh is compared against VINh. Warning bit Wx is set if VINh < VLOWh. Since VINl is always zero, it is
recommended that this register always be programmed to zero. This register is provided for compliance with SFF-
