GENERAL DESCRIPTION The ADT6501/ADT6502/ADT6503/ADT6504 are trip point temperature switches available in a 5-lead SOT-23 package. Each part contains an internal band gap temperature sensor for local temperature sensing. When the temperature crosses the trip point setting, the logic output is activated. The ADT6501/ ADT6503 logic output is active low and open-drain. The ADT6502/ADT6504 logic output is active high and push-pull. The temperature is digitized to a resolution of 0.125C (11-bit). The factory trip point settings are 10C apart starting from -45C to +15C for the cold threshold models and from +35C to +115C for the hot threshold models. These devices require no external components and typically consume 30 A supply current. Hysteresis is pin-selectable at 2C and 10C. The temperature switch is specified to operate over the supply range of 2.7 V to 5.5 V. The ADT6501 and ADT6502 are used for monitoring temperatures from +35C to +115C only. Therefore, the logic output pin becomes active when the temperature goes higher than the selected trip point temperature. Rev.

B | Page 7 of 16 ADT6501/ADT6502/ADT6503/ADT6504 Data Sheet THEORY OF OPERATION CIRCUIT INFORMATION FACTORY-PROGRAMMED THRESHOLD RANGE The ADT6501/ADT6502/ADT6503/ADT6504 are 11-bit digital temperature sensors with a 12th bit acting as the sign bit. An on-board temperature sensor generates a voltage precisely proportional to absolute temperature, which is compared to an internal voltage reference and input to a precision digital modulator. The 12-bit output from the modulator is input into a digital comparator where it is compared with a factory-set trip level. The output trip pin is activated if the temperature measured is greater than, in the case of the ADT6501/ADT6502, or less than, in the case of the ADT6503/ADT6504, the factory-set trip level. Overall accuracy for the ADT650x family is 6C (maximum) from -45C to +115C. The ADT6501/ADT6502/ADT6503/ADT6504 are available with factory-set threshold levels ranging from -45C to +115C in 10C temperature steps. The ADT6501/ADT6503 outputs are intended to interface to reset inputs of microprocessors. The ADT6502/ADT6504 are intended for driving circuits of applications such as fan control circuits. Table 4 lists the available temperature threshold ranges. The on-board temperature sensor has excellent accuracy and linearity over the entire rated temperature range without needing correction or calibration by the user. The ADT6501/ADT6503 have active low, open-drain output structures that can sink current. The ADT6502/ADT6504 have active high, push-pull output structures that can sink and source current. On powerup, the output becomes active when the first conversion is completed, which typically takes 30 ms. Table 4. Factory-Set Temperature Threshold Ranges Device ADT6501 ADT6502 ADT6503 ADT6504 Threshold (TTH) Range +35C < TTH < +115C +35C < TTH < +115C -45C < TTH < +15C -45C < TTH < +15C HYSTERESIS INPUT The sensor output is digitized by a first-order, - modulator, also known as the charge balance type analog-to-digital converter (ADC). This type of converter utilizes time domain oversampling and a high accuracy comparator to deliver 11 bits of effective accuracy in an extremely compact circuit. The HYST pin is used to select a temperature hysteresis of 2C or 10C. The digital comparator ensures excellent accuracy for the hysteresis value. If the HYST pin is connected to VCC, a hysteresis of 10C is selected. If the HYST pin is connected to GND, a hysteresis of 2C is selected. The HYST pin should not be left floating. Hysteresis prevents oscillation on the output pin when the temperature is approaching the trip point and after the output pin is activated. For example, if the temperature trip is 45C and the hysteresis selected is 10C, the temperature would have to go as low as 35C before the output deactivates. CONVERTER DETAILS TEMPERATURE CONVERSION The - modulator consists of an input sampler, a summing network, an integrator, a comparator, and a 1-bit digital-toanalog converter (DAC). Similar to the voltage-to-frequency converter, this architecture creates a negative feedback loop and minimizes the integrator output by changing the duty cycle of the comparator output in response to input voltage changes. The comparator samples the output of the integrator at a much higher rate than the input sampling frequency; this is called oversampling. Oversampling spreads the quantization noise over a much wider band than that of the input signal, improving overall noise performance and increasing accuracy. The conversion clock for the part is generated internally. No external clock is required. The internal clock oscillator runs an automatic conversion sequence. During this automatic conversion sequence, a conversion is initiated every 600 ms. At this time, the part powers up its analog circuitry and performs a temperature conversion. This temperature conversion typically takes 30 ms, after which the analog circuitry of the part automatically shuts down. The analog circuitry powers up again 570 ms later, when the 600 ms timer times out and the next conversion begins. The result of the most recent temperature conversion is compared with the factory-set trip point value. If the temperature measured is greater than the trip point value, the output is activated. The output is deactivated once the temperature crosses back over the trip point threshold plus whatever temperature hysteresis is selected. Figure 15 to Figure 18 show the transfer function for the output trip pin of each generic model. Rev.

Thermal mass is often considered equivalent to capacitance. Thermal conductivity is commonly specified using the symbol Q and can be thought of as thermal resistance. It is commonly specified in units of degrees per watt of power transferred across the thermal joint. Thus, the time required for the ADT650x to settle to the desired accuracy is dependent on the characteristics of the SOT-23 package, the thermal contact established in that particular application, and the equivalent power of the heat source. In most applications, the settling time is best determined empirically. If possible, the ADT650x should be powered directly from the system power supply. This arrangement, shown in Figure 19, isolates the analog section from the logic switching transients. Even if a separate power supply trace is not available, generous supply bypassing reduces supply line induced errors. Local supply bypassing consisting of a 0.1 F ceramic capacitor is advisable to achieve the temperature accuracy specifications. This decoupling capacitor must be placed as close as possible to the ADT650x VCC pin. TTL/CMOS LOGIC CIRCUITS SELF-HEATING EFFECTS 0.1F ADT650x POWER SUPPLY The temperature measurement accuracy of the ADT6501/ ADT6502/ADT6503/ADT6504 can be degraded in some applications due to self-heating. Errors can be introduced from the quiescent dissipation and power dissipated when converting. The magnitude of these temperature errors depends on the thermal conductivity of the ADT650x package, the mounting technique, and the effects of airflow. At 25C, static dissipation in the ADT650x is typically 99 W operating at 3.3 V. In the 5-lead SOT-23 package mounted in free air, this accounts for a temperature increase due to self-heating of T = PDISS x JA = 99 W x 240C/W = 0.024C It is recommended that current dissipated through the device be kept to a minimum because it has a proportional effect on the temperature error. SUPPLY DECOUPLING The ADT6501/ADT6502/ADT6503/ADT6504 should be decoupled with a 0.1 F ceramic capacitor between VCC and GND. This is particularly important when the ADT650x are mounted remotely from the power supply. Precision analog products such as the ADT650x require well filtered power sources. Because the ADT650x operate from a single supply, it may seem convenient to tap into the digital logic power supply. Unfortunately, the logic supply is often a switch-mode design, which generates noise in the 20 kHz to 1 MHz range. In addition, fast logic gates can generate glitches that are hundreds of mV in amplitude due to wiring resistance and inductance. 06096-010 THERMAL RESPONSE TIME Figure 19. Separate Traces Used to Reduce Power Supply Noise TEMPERATURE MONITORING The ADT6501/ADT6502/ADT6503/ADT6504 are ideal for monitoring the thermal environment within electronic equipment. For example, the surface-mount package accurately reflects the exact thermal conditions that affect nearby integrated circuits. The ADT650x measure and convert the temperature at the surface of its own semiconductor chip. When the ADT650x are used to measure the temperature of a nearby heat source, the thermal impedance between the heat source and the ADT650x must be as low as possible. As much as 60% of the heat transferred from the heat source to the thermal sensor on the ADT650x die is discharged via the copper tracks, package pins, and bond pads. Of the pins on the ADT650x, the GND pins transfer most of the heat. Therefore, to monitor the temperature of a heat source, it is recommended that the thermal resistance between the ADT650x GND pins and the GND of the heat source be reduced as much as possible. For example, the unique properties of the ADT650x can be used to monitor a high power dissipation microprocessor. The ADT650x device in its SOT-23 package is mounted directly beneath the microprocessor's pin grid array (PGA) package. The ADT650x requires no external characterization. Rev.
