Resistor-Programmable Temperature Switches
Description
Features
• Resistor-Programmable Temperature Switch
Microchip Technology’s MCP9509/10 devices are pro-
grammable logic output temperature switches. The
temperature switch threshold can be programmed with
a single external resistor, which provides high design
flexibility and simplicity. In addition, this family of
devices provide user programmable features such as
2°C and 10°C (typical) switch hysteresis and output
structure configuration. The MCP9509 provides an
open drain output, whereas the MCP9510 is offered in
three different user selectable output configurations:
Active-low/Active-high push pull and Active-Low
Open-Drain output with an internal 100 kΩ pull-up
resistor.
• Wide Operating Voltage Range: 2.7V to 5.5V
• Low Supply Current: 30 µA (typical)
• Temperature Switch Accuracy:
- ±0.5°C (typical) at +25°C, +45°C
- ±1°C (typical) 0°C to +70°C
- ±3.5°C (maximum) 0°C to +125°C
- ±4.5°C (maximum) -20°C to +125°C
- ±2°C (typical) -40°C to +125°C
• Sensor Options available:
- Switch for rising temperature: Cold to Hot (H)
- Switch for falling temperature: Hot to Cold (C)
• Output Configurations:
The MCP9509/10 operate from 2.7V to 5.5V. This
family is capable of triggering for temperatures -40°C to
+125°C with high accuracy.
- Open-Drain:
– External Pull-up Resistor: MCP9509

FUNCTIONAL DESCRIPTION
VDD
MCP9510
The MCP9509/10 integrates a temperature switch with
a user programmable threshold. The temperature
switch threshold or alert limit is programmed using an
external resistor RSET. A logic signal is asserted when
the die temperature crosses the programmed alert
limit. The MCP9509 has an Open-Drain output which
requires an external pull-up resistor for operation. The
MCP9510 output can be configured to three user
selectable output configurations. The OUTSET pin is
used to select Active-Low Push-Pull, Active-Low
Open-Drain (with internal 100 kΩ pull-up resistor),
Active-High Push-Pull output configurations. In addi-
tion, this device provides user selectable hysteresis of
2°C and 10°C (typical).

4.1
SET Input Pin
The SET input pin is used to connect an external
resistor RSET. The resistor sets the alert threshold. The
SET pin outputs a constant current ISET (~5 µA) to bias
RSET (Shown in Figure 4-1). The voltage across RSET,
VSET, is compared to an internal thermal diode.
The OUTSET pin input impedance ZOUTSET is set by
the internal resistance RA = 1 MΩ (typical). The input
structure is a voltage divider network from VDD
Therefore, the leakage current on the OUTSET pin is a
function of change in VDD and the VOSET
.
.
4.3
HYST Input Pin (Hysteresis Select)
ISET
The MCP9509/10 family has a user selectable
hysteresis input pin HYST. Hysteresis can be externally
selected to either 2°C (HYST = GND) or 10°C
(HYST = VDD). Figure 4-3 shows graphical description
of change in hysteresis.

For example, if the alert temperature threshold is set to
TSET = 100°C (RSET = 16.1 kΩ) with an Active-Low out-
put configuration, the output asserts Low when temper-
ature exceeds 100°C ± TACY. The output remains
asserted Low until temperautre falls below THYST, 98°C
(HYST = GND) or 90°C (HYST = VDD).

MCP9510 OUTSET Input Pin
This pin is used to select the device output configura-
tion. This feature enables in-circuit device output con-
figuration by driving this pin with a microcontroller I/O
pin to Output-HIGH, Output-LOW, or High-Impedance
input. Figure 4-4 shows the configuration and output
conditions.

The input structure of this pin consists of a resistor lad-
der and comparators to determine OUTSET level
threshold. Figure 4-2 shows the circuit configuration.
The OUTSET input resistance must be carefully
considered for leakage current when connecting volt-
age source to change output configuration.

Sensor Hot/Cold Options
CONVERSION
MCP9509/10 is available with Hot (H) and Cold (C)
options. The MCP9509/10 Hot option detects rising
temperature while the Cold option detects falling tem-
perature. The output of the Hot option asserts when
temperature rises above TSET and de-asserts when
temperature falls below THYST. The output of the Cold
option asserts when temperature falls below TSET and

Where:

(Table 4-1)
de-asserts when temperature rises above THYST
.
For example, if TSET = 100°C for Hot option
(Active-Low Configuration, HYST = VDD), output
asserts Low when temperature is greater than
100°C ± TACY. The output de-asserts High when
temperature is below 90°C. For the Cold option, output
asserts Low when temperature is less than
100°C ± TACY, and de-asserts when temperature is
greater than 110°C. This operation is shown graphically
in Figure 4-4.

Application Information
The MCP9509/10 temperature switch integrates a
temperature sensor and a comparator circuit which out-
puts an alert signal when the user programmed tem-
perature threshold is exceeded. The external resistor
value to set the output threshold can be determined
using Table 4-2. A constant current source ISET = 5 µA
(typical) biases the external resistor RSET. A thermal
diode is used to measure ambient temperature. When
the voltage across the thermal diode exceeds the volt-
age across RSET, VSET, the sensor output asserts. The
sensor output de-asserts when the diode voltage drops
below VSET and the user selected hysteresis level.

The MCP9509/10 provide Open-drain output where
multiple sensors from multiple PCB hot-spots can be
connected to a single processor I/O input with a
wired-Or Configuration. The MCP9509 requires an
external pull-up resistor which can be used to level-shift
the alert signal. For example, if the sensors are
powered with 5VDD and the controller or processor is
powered with 3VDD, the external resistor can be
level-shifted by connecting 3VDD to the pull-up resistor
as shown in Figure 4-5. The MCP9510 elliminates the
need for an external resistor while providing wired-Or
function (Figure 4-6). The MCP9510 also provides
push-pull output configuration for a direct connection to
the processor with Active-Low or Active-High assert
polarities.

LAYOUT CONSIDERATION AND
THERMAL CONSIDERATION
This family of sensors measure temperature by moni-
toring the voltage level of a thermal diode located in the
die. A low-impedance thermal path between the die
and the PCB is provided by the pins. Therefore, the
sensor effectively monitors PCB temperature. For
efficient performance, it is recommended to layout the
device as close to the heat source as possible. It is also
recommended to use a de-coupling capacitor of 0.1 µF
to 1 µF between VDD and GND pins for stability.

When connecting an external resistor to the MCP9509
device, the current through the pull-up resistor must be

POWER SUPPLY REJECTION
The MCP9509/10 family of sensors are designed to
prevent false output trigger due to high frequency
power supply or system noise. Figure 4-7 shows
device performance with a high frequency signal added
on VDD. The output is not triggered due to the signal
added on VDD
recommended to add a bypass capacitor of 0.1 µF to
1 µF.
VDD = 5.5V, VOL = 0.3V and IOUT = 5 mA (see specifi-
cation table), the self heating due to power dissipation
(TJ - TA) is ~0.4°C.

. With some applications, it is
MICROCONTROLLER I/O PIN
The OUTSET pin can be controlled using a Microcon-
troller input/output (I/O) pin. I/O levels HIGH and LOW
provide push-pull configuration with Active-High and
Active-Low outputs, respectively. The Open-Drain
output with internal pull-up resistor can be selected by
configuring the I/O pin as a High-Impedance Input. The
Open-Drain output can also be selected by forcing volt-
age level VOSET from a low impedance source. With
this configuration, there maybe some leakage current
due to impedance mismatch, (See Figure 4-2).

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.
