Summary of Power-up Condition
The fault queue feature can be used as a filter to lessen
the probability of spurious activation of the ALERT pin.
T A must remain above T SET for the consecutive
number of conversion cycles selected using the Fault
Queue bits. Bit 3 and bit 4 of CONFIG can be used to
select up to six fault queue cycles. For example, if six
The MCP9800/1/2/3 has an internal Power-on Reset
(POR) circuit. If the power supply voltage V DD glitches
down to the 1.7V (typical) threshold, the device resets
the registers to the power-up default settings.
Power-up Defaults
fault queues are selected, T A must be greater than
T SET for six consecutive conversions before ALERT is
asserted as a comparator or an interrupt output.
This queue setting also applies for T HYST . I f six fault
queues are selected, T A must remain below T HYST for
six consecutive conversions before ALERT is
deasserted (Comparator mode) or before another
interrupt is asserted (Interrupt mode).

At power-up, the MCP9800/1/2/3 has an inherent 2 ms
(typical) power-up delay before updating the registers
with default values and start a conversion cycle. This
delay reduces register corruption due to unsettled
power. After power-up, it takes t CONV for the TCN75A
to update the T A register with valid temperature data.
