2008 microchip technology inc. 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 t hyst . the output of the cold option asserts when temperature falls below t set and de-asserts when temperature rises above t hyst . for example, if t set = 100c for hot option (active-low configuration, hyst = v dd ), output asserts low when temperature is greater than 100c t acy . the output de-asserts high when temperature is below 90c. for the cold option, output asserts low when temperature is less than 100c t acy , and de-asserts when temperature is greater than 110c. this ope ration is shown graphically in figure 4-4 . 4.5 r set vs. temperature the relation between the user selectable external resistor r set and the output trigger threshold limit t set is described as shown in equation 4-1: ?t set to r set conversion? and equation 4-2: ?r set to t set 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 r set conversion equation 4-2: r set to t set 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 ta b l e 4 - 3 show a look-up table which can be used to easily identify the t set to r set relation for hot and cold options. coef.

2008 microchip technology inc. 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 ta b l e 4 - 2 . a constant current source i set = 5 a (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 r set , v set , the sensor out put 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 3v dd 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 configurati on 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 thermal consideration 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 f to 1 f 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 . equation 4-3: effect of self-heating set out hyst 5v dd set r set out hyst 5v dd i/o 3v dd r pull_up micro- controller r set MCP9509 MCP9509 3v dd set out hyst 5v dd set r set out hyst 5v dd i/o micro- controller r set mcp9510 mcp9510 outset outset 5v dd where: t j = junction temperature t a = ambient temperature ja = package thermal resistance (220.7 c/w) v ol = sensor output low voltage i out = output current t j t a ?
