Rainbow Electronics MAX6508 - Manual (Page 8)

Temperature-Window Alarm
The MAX6507 and MAX6508 have an output (OK, OK)
that indicates the die temperature is within the selected
temperature window. This output is asserted when
within the window, and deasserted when outside the
window. Additionally, a second digital output indicates
when the die temperature is above the upper set point.
This is useful in systems where operation is optimized
over a predetermined temperature range. The thermal
overrange signal can be used to assert a thermal shut-
down, power-up, recalibration, or other temperature-
dependent function (Figure 4 and Typical Operating
Circuits).

Temperature Code
*Two hex codes are used in the suffix. The first indicates the
the low trip temperature and the second indicates the high trip
temperature. For example, the MAX6507UT8255-T has a lower
trip point of -40
°C and an upper trip point of +85°C.
