• Manufacturer Part Number: MIC280
• Description: Precision IttyBitty Thermal Supervisor
• Manufacturer: MICREL [Micrel Semiconductor]

Each LSB represents one-sixteenth degree centigrade. The values are in a binary format such that 1/16th°C (0.0625°C) is
reported as 0001 0000
Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.
Each LSB represents one degree centigrade. The values are in a two’s complement binary format such that 0°C is reported
as 0000 0000
Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.
