NAME
FUNCTION
________________General Description
The MAX6501–MAX6504 fully integrated temperature
switches incorporate two temperature-dependent refer-
ences and a comparator. One reference exhibits a pos-
itive temperature coefficient and the other a negative
temperature coefficient (Figure 1). 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
die temperature approaches the threshold temperature.
The MAX6501/MAX6503 have an active-low, open-
drain output structure that can only sink current. The
MAX6502/MAX6504 have an active-high, push-pull out-
put structure that can sink or source current. The inter-
nal power-on reset circuit guarantees the output is at
TTH = +25°C state at startup for 50s.
The MAX6501–MAX6504 are available with factory-
preset temperature thresholds from -45°C to +125°C in
10°C increments. Table 1 lists the available temperature
threshold ranges. The MAX6501/MAX6503 outputs are
intended to interface with a microprocessor (P) reset
input (Figure 2). The MAX6502/MAX6504 outputs are
intended for applications such as driving a fan control
(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
approaches the trip point. The HYST pin should not be
left unconnected. Drive HYST close to ground or VCC.
Other input voltages cause increased supply current.
The actual amount of hysteresis depends on the part’s
programmed trip threshold (see the
Typical Operating
Characteristics).
