MIC280 MICREL [Micrel Semiconductor], MIC280 Datasheet - Page 15

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

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.
