Summary of Power-on Default

The MCP9808 has an internal Power-on Reset (POR)

circuit. If the power supply voltage, VDD, glitches below

the VPOR threshold, the device resets the registers to

the power-on default settings.

Table 5-3 shows the power-on default summary for the

Temperature Sensor registers.
