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°C or 10°C
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°C to +125°C.
The temperature threshold is set by an external resistor
between SET and GND. The MAX6509 output easily
interfaces with a microprocessor (P) 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°C for HYST = VCC)
or a low level (2°C 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 VCC. 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°C will assert when its temperature rises
above +100°C, and will not deassert until its tempera-
ture drops below +100°C minus the selected hysteresis
value (e.g., +98°C if 2°C hysteresis is chosen). Con-
versely, if the trip temperature of a MAX6509CAUK-T or
MAX6510CAUT-T is -40°C, the output asserts at
-40°C as temperature falls, and deasserts when tem-
perature rises above -40°C plus the hysteresis value
(e.g., -38°C if 2°C 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).
