Detailed Description
The MAX6513 fully integrated temperature switch incor-
porates a precision bandgap reference, a conversion
block, a current source, and a comparator (Figure 1).
The device uses an external P-N junction as the tem-
perature-sensing element. It steers bias currents
through the external diode, measures the forward volt-
ages, and computes the temperature using a precision
chopper stabilized amplifier.
Resistance values of less than 100?in series with the
external sense junction will result in trip-point errors
< 1癈. The MAX6513 provides noise immunity by inte-
gration and oversampling of the diode voltage, but
good design practice includes routing the DXP and
DXN lines away from noise sources, such as high-
speed digital lines, switching regulators, inductors, and
transformers. The DXP and DXN traces should be
paired together and surrounded by ground plane
whenever possible.
In applications where the temperature changes rapidly,
the measured temperature will be approximately equal
to the average value of the temperature during the
measurement period.
The MAX6513 has an active-high CMOS output, and is
available with preset temperature thresholds from
+45癈 to +125癈 in 10癈 increments.

DXN
This pin connects to the
negative (cathode) terminal of
the external P-N sense junction.
DXN must be connected to GND.
