Preliminary

Figure 13.

6.4.3.2 Comparator Mode :

At this mode, temperature exceeding TO causes the OVT# output activated until the temperature

is less than THYST. ( Figure 14)

6.4.3.3 Interrupt Mode:

At this mode, temperature exceeding TO causes the OVT# output activated indefinitely until reset

by reading CPUT1 or CPUT2 registers. Temperature exceeding TO , then OVT# asserted, and

then temperature going below THYST will also cause the OVT# activated indefinitely until reset by

reading temperature sensor2 or sensor 3 registers. Once the OVT# is activated by exceeding TO

, then reset, if the temperature remains above THYST , the OVT# will not be activated again.(
