Detailed Description
The MAX6509/MAX6510 fully integrated temperature
switches incorporate two temperature-dependent refer-
ences and one comparator. One reference exhibits a
positive temperature coefficient, and the other has a
negative temperature coefficient. The temperature at
which the two reference voltages are equal determines
the temperature trip point. Pin-selectable 2癈 or 10癈
hysteresis keeps the output from oscillating when the
temperature is close to the threshold. The MAX6509
has an active-low, open-drain output structure that can
only sink current. The MAX6510 has three different out-
put options from which to choose (Table 1).
The MAX6509/MAX6510 are programmable for a wide
range of temperature thresholds from -40癈 to +125癈.
The temperature threshold is set by an external resistor
between SET and GND. The MAX6509 output easily
interfaces with a microprocessor (礟) reset input
(Figure 2). The MAX6510 output is intended for applica-
tions such as driving a fan control switch (Figure 3).
Hysteresis Input
The HYST pin is a CMOS-compatible input that selects
hysteresis at either a high level (10癈 for HYST = V
CC
)
or a low level (2癈 for HYST = GND). Hysteresis pre-
vents the output from oscillating when the temperature
is near the trip point. Do not leave HYST unconnected.
Connect HYST to GND or V
CC
. Other input voltages
cause increased supply current.
Choose the set-hot temperature (H) or set-cold temper-
ature (C) option to ensure that the trip point is accurate
and the hysteresis is in the right direction. A MAX6509
or MAX6510 with the H suffix will first trip at the correct
point when temperature is increasing. For example, a
MAX6509HAUK+T or MAX6510HAUT+T with its trip
point set to 100癈 will assert when its temperature rises
above +100癈, and will not deassert until its tempera-
ture drops below +100癈 minus the selected hysteresis
value (e.g., +98癈 if 2癈 hysteresis is chosen). Con-
versely, if the trip temperature of a MAX6509CAUK+T
or MAX6510CAUT+T is -40癈, the output asserts at
-40癈 as temperature falls, and deasserts when tem-
perature rises above -40癈 plus the hysteresis value
(e.g., -38癈 if 2癈 hysteresis is chosen) as shown in
Figure 4.
Output Selection
The MAX6509 provides an open-drain output. The
MAX6510 features three output options selectable by
OUTSET (Table 1).
