Features
General Description
• 5-Pin SOT-23A
• Factory-programmed Thresholds from
-45°C to +125°C in 10°C Increments
• Pin Selectable +2°C or +10°C Hysteresis
• ±0.5°C (Typ) Threshold Accuracy Over Full
Temperature Range
• No External Components Required
• 17 µA Supply Current (Typ)
The TC6501/2/3/4 are SOT-23 temperature switches
that require no external components and are available
with factory-programmed temperature thresholds. A
choice of factory-trimmed temperature trip points are
also available. Pin-selectable hysteresis of +2°C or
+10°C allows flexibility to the design of the application.
These parts typically consume only 17 µA of current
and operate over the entire -55°C to +135°C
temperature range, while offering accuracies of ±0.5°C
(typ).

The TC6501 and TC6503 have an open-drain, activelow output, which targets microcontroller reset control.
The TC6502 and TC6504 have a CMOS, active-high
output designed to drive the logic level MOSFET that
turns on a fan or heater element.
The TC6501/TC6502 are designed for hot temperature
monitoring (+35°C to +125°C). These devices assert a
logic signal when the temperature goes above the
threshold. The TC6503/TC6504 are optimized for cold
temperature monitoring (-45°C to +15°C) and assert a
logic signal when the temperature goes below the
threshold.
The TC6501/2/3/4 are offered with five standard temperature thresholds. Available in 5-Pin SOT-23A packages, these parts are ideal for applications requiring
high integration, small size, low power and low installed
cost.

Description
Open-Drain, Active-Low Output
(TC6501) (TOVER)
The voltage at the TOVER pin is equal to a logic-low
level if the sensor detects a temperature that is greater
than the factory-programmed threshold temperature.
Because this is an open-drain output, an external pullup resistor is required (a 100 k pull-up resistor is
recommended). The voltage on this pin can be higher
than VCC, though the voltage must not exceed the
absolute maximum input voltage of 7.0V.

Open-Drain, Active-Low Output
(TC6503) (TUNDER)

Because this is an open-drain output, an external pullup resistor is required (a 100 k pull-up resistor is
recommended). The voltage on this pin can be higher
than VCC, though the voltage must not exceed the
absolute maximum input voltage of 7.0V

DETAILED DESCRIPTION
4.2
Thermal Considerations
The TC6501/2/3/4 integrate a temperature sensor with
a factory-programmed threshold switch (see Functional
Block Diagrams in Figure 5-4 through Figure 5-7). A
logic signal is asserted when the die temperature
crosses the factory-programmed threshold. An external
hysteresis input pin allows the user to select either 2°C
or 10°C hysteresis to give further flexibility to the design
of the application. The TC6501 and TC6502 are
intended for a temperature range of 35°C to 125°C in
10°C increments. The TC6501 has an open-drain
output, while the TC6502 has a push-pull output stage.
With a 17 µA typical supply current, the TC6501/2/3/4
dissipates very little power. Thus, the die temperature
is basically the same as the package temperature. To
minimize the error in temperature readings, the load
current should be limited to a few milliamps. For
example, the typical thermal resistance of a 5-Pin SOT23A package is 140°C/W. If, for instance, the TC6501
had to sink 1 mA, and the output voltage is ensured to
be less than 0.3V, an additional 0.3 mW of power is
dissipated within the temperature sensor. This
corresponds to a 0.042°C rise in die temperature.
The TC6503 and TC6504 are intended for a cold
temperature range of -45°C to +15°C in 10°C
increments. The TC6503 has an open-drain output,
while the TC6504 has a push/pull output stage. The
TC6501 and TC6503 are intended for applications with
a microcontroller reset input. The TC6502 and TC6504
are intended for applications where a fan or heater
element is turned on.
Temperature-monitoring accuracy depends on the
thermal resistance between the device being
monitored and the temperature switch die. Heat flows
primarily through the leads onto the die. Pin 2 provides
the lowest thermal resistance to the die. To achieve the
best temperature-monitoring results, the TC6501/2/3/4
should be placed closest to the device being
monitored. Additionally, a short and wide copper trace
from pin 2 to the device should be used. In some cases,
the 5-Pin SOT-23A package can be placed directly
under the socketed microcontroller for improved thermal contact.
Please contact Microchip Technology for the availability
of a particular temperature threshold not included in
Table 4-1.
4.1
Hysteresis Input
To prevent the output from “chattering” at or near the
trip point temperature, a selectable HYST input pin is
provided. Hysteresis can be externally selected at 2°C
(HYST = GND) or 10°C (HYST = VCC) by means of the
CMOS compatible HYST input pin. Do not let the HYST
pin float, as this could cause an increase in supply
current. The hysteresis does not depend on the part’s
programmed trip threshold.

APPLICATIONS
The TC6501 and TC6503 have open-drain outputs and
are, therefore, intended to interface as microcontroller
reset inputs. Moreover, the combination of these two
devices can be used to implement a temperature
window alarm by wire-ORing the outputs and using an
external pull-up resistor (see Figure 5-1).
The TC6504, with its push-pull output, may be used in
a similar fashion to turn on a heater element at cold
temperatures (see Figure 5-3).

The TC6502 can be used to control a DC fan. The fan
turns on when the sensed temperature rises above the
factory-set threshold and remains on until the
temperature falls below threshold minus the hysteresis
selected. An additional fail-safe measure could be
designed by using a second TC6502 with a higher
temperature threshold to alert the user of an impending
thermal shutdown, should the temperature continue to
rise (see Figure 5-2).

 2002-2012 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
