Description

Microchip Technology’s MCP9509/10 devices are pro- grammable logic output te mperature 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 progr ammable 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 selectab le output configurations: Active-low/Active-high push pull and Active-Low Open-Drain output with an internal 100 k Ω pull-up resistor. 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.

3.0 PIN DESCRIPTIONS

TABLE 3-1: PIN FUNCTION TABLE

3.1 External Resistor Input (SET)

This pin is used to connect a resistor between the SET and GND pins to select the temperature trip point (TSET). The resistor value can be determined either from Equation 4-2 or the lookup table shown in Table 4-2.

3.2 Ground (GND)

The GND pin is the system ground pin.

3.4 Power Pin (V DD)

The operating voltage range, as specified in the DC electrical specification table, is applied on this pin.

3.5 Open-Drain Output (OUT )

(MCP9509) This output is triggered when temperature exceeds the programmed trip temperatur e. This pin requires a pull-up resistor.

3.6 Selectable Output (OUT, OUT )

(MCP9510) The output pin can be configured as either a Push-Pull Active-High, Push-Pull Active-Low, or an Open-drain Output with an internal pull-up resistor. The three output options of the MCP9510 are selected by the OUTSET pin.

4.0 FUNCTIONAL DESCRIPTION

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 k Ω 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. FIGURE 4-1: SET input. When the thermal diode voltage exceeds V SET, the sensor output asserts. The assert polarity is determined by the state of the OUTSET pin.

4.2 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, Out put-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. FIGURE 4-2: MCP9510 OUTSET Input Structure. The OUTSET pin input impedance Z OUTSET is set by the internal resistance R A = 1 M Ω (typical). The input structure is a voltage divider network from V DD. Therefore, the leakage current on the OUTSET pin is a function of change in V DD and the VOSET.

4.3 HYST Input Pin (Hysteresis Select)

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 = V DD). 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 ± T ACY. The output remains asserted Low until temperautre falls below THYST, 98°C (HYST = GND) or 90°C (HYST = VDD). FIGURE 4-3: Output Hysteresis.

4.4 Sensor Hot/Cold Options

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 T SET and de-asserts when temperature falls below THYST. The output of the Cold option asserts when temperature falls below TSET and de-asserts when temperature rises above THYST. For example, if T SET = 100°C for Hot option (Active-Low Configuration, HYST = V DD), 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. 4.5 R SET vs. Temperature The relation between the user selectable external resistor RSET and the output trigger threshold limit TSET is described as shown in EQUATION 4-1: “T SET to Rset conversion” and EQUATION 4-2: “RSET to Tset conversion”. The equation coeffcients vary depending on the device output options, H or C. Table 4-1 shows the corresponding coefficients. TABLE 4-1: COEFFICIENTS/VARIABLES EQUATION 4-1: T SET TO RSET CONVERSION EQUATION 4-2: R SET TO TSET CONVERSION The equations can be used to determine the external resistance value for a specified temperature threshold or threshold value for a specified resistance. Table 4-2 and Table 4-3 show a look-up table which can be used to easily identify the TSET to RSET relation for Hot and Cold options. Coef.

4.6 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 I SET = 5 µA (typical) biases the external resistor R SET. 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 V SET and the user selected hysteresis level. The MCP9509/10 provide Open-drain output where multiple sensors from mu ltiple 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 5V DD and the controller or processor is powered with 3V DD, 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. FIGURE 4-5: MCP9509 Wired-Or Output Configuration with Level-shift. FIGURE 4-6: MCP9510 Wired-Or Output Configuration with Internal Pull-up Resistor.

4.6.1 LAYOUT CONSIDERATION AND

This family of sensors me asure 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 V DD and GND pins for stability. When connecting an external resistor to the MCP9509 device, the current through the pull-up resistor must be considered to prevent self-heat due to power. This can be determined using Equation 4-3.

© 2008 Microchip Technology Inc. DS22114A-page 17 MCP9509/10 For example, at room temperature, when output asserts Active-Low and maximum I DD = 50 µA, VDD =5 . 5 V , VOL = 0.3V and IOUT = 5 mA (see specifi- cation table), the self heating due to power dissipation (TJ - TA) is ~0.4°C.

4.6.2 DRIVING OUTSET WITH A

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 V OSET from a low impedance source. With this configuration, there maybe some leakage current due to impedance mismatch, (See Figure 4-2).

4.6.3 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 V DD. With some applications, it is recommended to add a bypass capacitor of 0.1 µF to 1µ F .
