These devices are ideal for high-power supply systems where an overtemperature protection circuit is needed. These devices do not require external components, consume 25 A (typical), and the factory set thresholds provide simplicity. In addition, this family of devices provides user-selectable +2C and +10C (typical) switch hysteresis, and various output configurations. The MCP9501/2 outputs switch for rising temperatures, while the MCP9503/4 devices switch for falling temperatures, with the relative hysteresis at the set thresholds. This family of devices is also available with an active-high, push-pull output (MCP9502/4) and an active-low, open-drain output (MCP9501/3). The push-pull output is ideal for a microcontroller interface, while the open-drain output can be used for level shifting, wired-OR configuration or as a heater on/off switch. The MCP9501/2/3/4 devices operate from a 2.7V to 5.5V supply. This family is available with the space-saving 5-lead SOT-23 package.

Pin 2 must be connected to system ground. Pin 1 can also be connected to system ground which would provide better thermal conduction to the die. 3.2 Hysteresis Input (HYST) This is an input pin which can be connected to VDD or GND to select the output hysteresis. Either +2C (HYST = GND) or +10C (HYST = VDD) of the typical hysteresis can be selected. 2011-2016 Microchip Technology Inc. 3.3 Power Pin (VDD) The operating voltage range, as specified in the "DC Characteristics" table, is applied to this pin. 3.4 Switch Output (Output) This output is triggered when the temperature rises or falls beyond the programmed trip temperature threshold. MCP9501/3 devices require an external pull-up resistor. DS20002268B-page 7 MCP9501/2/3/4 NOTES: DS20002268B-page 8 2011-2016 Microchip Technology Inc. MCP9501/2/3/4 FUNCTIONAL DESCRIPTION Rx + FIGURE 4-1: V THYST Cold TSET Hot Temperature OUT/ OUT - +10C Typical Hysteresis +2C Typical Hysteresis Hysteresis Select Pin ISET Threshold Select Hot Option (Active-Low) Output The MCP9501/2/3/4 temperature switch family integrates a thermal diode, a comparator and a factory-selectable resistive network used to set the temperature thresholds. The available output thresholds range from -35C to +125C at 10C increments. There is no additional configuration required to operate this device. The selectable output hysteresis is controlled using a single input pin. When this pin is connected to ground, the output hysteresis is +2C (typical), and when connected to VDD, the output hysteresis is +10C (typical). Figure 4-1 shows the functional block diagram. Cold Option (Active-High) +10C Typical Hysteresis V +2C Typical Hysteresis Thermal Diode Functional Block Diagram. There are two output configurations for this family: a push-pull, and an open-drain output with active-high and active-low assertions. These assertion options are referred to as Cold and Hot options, primarily due to the direction of the selected hysteresis. For the Cold option, temperature has to fall below the threshold for the output to assert high and deassert low when the temperature rises above the threshold plus the hysteresis. For example, for a +65C threshold and +2C (typical) hysteresis, when temperature falls below +65C, the output asserts high and deasserts low when temperature rises above +67C. For the Hot option, the opposite is true. When temperature rises above +65C, the output asserts low and deasserts high when the temperature falls below +63C. Figure 4-2 shows a graphical description for the Hot and Cold options. 2011-2016 Microchip Technology Inc. Output 4.0 TSET Cold THYST Hot Temperature FIGURE 4-2: Output Hysteresis. The push-pull output is ideal for a microcontroller interface using an input/output pin or an interrupt input pin. The open-drain option can be used with multiple sensors in a wired-OR configuration or as a level shifter. DS20002268B-page 9 MCP9501/2/3/4 4.1 4.1.1 Application Information The MCP9501/2/3/4 temperature switch family integrates a temperature sensor and a comparator circuit, which outputs an alert signal when the factory set temperature threshold is exceeded. No additional component is required for device operation, which provides simplicity to the system designer. The device output options provide design flexibility for various applications, such as overtemperature protection circuit or a closed-loop temperature control unit. This device can be interfaced to a closed-loop fan controller network without the need for a microcontroller. 12V 5 VDD HYST MCP9502 LAYOUT CONSIDERATION AND THERMAL CONSIDERATION This family of sensors measures temperature by monitoring 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. When connecting an external resistor to the MCP9501/3, the current through the pull-up resistor must be considered to prevent self-heat due to power. This can be determined using Equation 4-1. EQUATION 4-1: M EFFECT OF SELF-HEATING TJ - TA = JA VDD I DD + V OL IOUT Output Where: TJ = Junction Temperature TA = Ambient Temperature FIGURE 4-3: MCP9502. Fan Controller Using VOL = Sensor Output Low Voltage The MCP9501/2/3/4 family provides an open-drain output, where multiple sensors from multiple PCB hotspots, can be connected to a single processor I/O input with a wired-OR configuration. The MCP9501 requires an external pull-up resistor, which can be used to level shift the alert signal. For example, if the sensors are powered with 5 VDD and the controller or processor is powered with 3 VDD, the external resistor can be level shifted by connecting 3 VDD to the pull-up resistor, as shown in Figure 4-4. 5 VDD 5VDD IOUT = Output Current For example, at room temperature, when the output asserts active-low and the maximum IDD = 50 A, VDD = 5.5V, VOL = 0.3V and IOUT = 5 mA (see "DC Characteristics"), the self-heating due to power dissipation (TJ - TA) is ~0.4C. 3 VDD RPULL_UP HYST MCP9501 OUT +85C JA = Package Thermal Resistance (220.7C/W) MCU I/O HYST MCP9503 OUT +35C FIGURE 4-4: MCP9501 Wired-OR Output Configuration with Level Shift. DS20002268B-page 10 2011-2016 Microchip Technology Inc. MCP9501/2/3/4 4.1.2 POWER SUPPLY REJECTION The MCP9501/2/3/4 family does not require any additional components. However, it is recommended that a decoupling capacitor of 0.1 F to 1 F be used between the VDD and GND pins. A high-frequency ceramic capacitor is recommended. It is necessary for the capacitor to be located as close as possible to the power pins in order to provide effective noise protection. The MCP9501/2/3/4 family of sensors is designed to prevent false output triggers due to high-frequency power supply or system noise. Figure 4-6 shows the device performance with a high-frequency signal added on VDD. The output is not triggered due to the signal added on VDD. With some applications, it is recommended to add a bypass capacitor of 0.1 F to 1 F.

It is also recommended to add the series resistor in applications where a linear regulator is used to step-down a switching regulator voltage to power the sensor, as shown in Figure 4-5. For example, if a linearly regulated 3.3V from a 5V switching regulator is used to power the sensor, add a 200 series resistor. 2011-2016 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.
