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.

Because this is an open-drain output, an external pullup resistor is required (a 100 kΩ 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. 2004 Microchip Technology Inc.

Because this is an open-drain output, an external pullup resistor is required (a 100 kΩ pull-up resistor is recommended).

DS21451D-page 5 TC6501/2/3/4 4.0 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.

TC6501/2/3/4 5.0 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). 12V +5V 100 pF VCC +5V Heater TC6504 RPULL-UP 100 kΩ 100 pF 100 pF Temperature TUNDER Out of Range VCC VCC TC6501 TC6501 TC6503 TC6503 GND GND HYST Temperature TUNDER UNDER TOVER OVER HYST GND GND HYST GND GND HYST GND GND GND HYST GND FIGURE 5-1: Over and Under Temperature Alarm. 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).
