An with factory-set threshold levels ranging from −45°C to +115°C on-board temperature sensor generates a voltage precisely in 10°C temperature steps. The ADT6501/ADT6503 outputs are proportional to absolute temperature, which is compared to intended to interface to reset inputs of microprocessors. The an internal voltage reference and input to a precision digital ADT6502/ADT6504 are intended for driving circuits of modulator. The 12-bit output from the modulator is input into a applications such as fan control circuits. Table 4 lists the digital comparator where it is compared with a factory-set trip available temperature threshold ranges. level. The output trip pin is activated if the temperature measured Table 4.

If the HYST pin is connected to V , a hysteresis up, the output becomes active when the first conversion is CC of 10°C is selected. If the HYST pin is connected to GND, a completed, which typically takes 30 ms. hysteresis of 2°C is selected. The HYST pin should not be left The sensor output is digitized by a first-order, ∑-∆ modulator, floating. Hysteresis prevents oscillation on the output pin when also known as the charge balance type analog-to-digital the temperature is approaching the trip point and after the converter (ADC). This type of converter utilizes time domain output pin is activated. For example, if the temperature trip is oversampling and a high accuracy comparator to deliver 11 bits 45°C and the hysteresis selected is 10°C, the temperature would of effective accuracy in an extremely compact circuit. have to go as low as 35°C before the output deactivates. CONVERTER DETAILS TEMPERATURE CONVERSION The Σ-Δ modulator consists of an input sampler, a summing The conversion clock for the part is generated internally. No network, an integrator, a comparator, and a 1-bit digital-to- external clock is required. The internal clock oscillator runs an analog converter (DAC). Similar to the voltage-to-frequency automatic conversion sequence. During this automatic conversion converter, this architecture creates a negative feedback loop and sequence, a conversion is initiated every 600 ms. At this time, the minimizes the integrator output by changing the duty cycle of part powers up its analog circuitry and performs a temperature the comparator output in response to input voltage changes. conversion. The comparator samples the output of the integrator at a much This temperature conversion typically takes 30 ms, after which higher rate than the input sampling frequency; this is called the analog circuitry of the part automatically shuts down. The oversampling. Oversampling spreads the quantization noise analog circuitry powers up again 570 ms later, when the 600 ms over a much wider band than that of the input signal, timer times out and the next conversion begins. The result of improving overall noise performance and increasing accuracy. 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.
