MAX6501-MAX6504 Low-Cost, Fully Integrated tem-Temperature Sensor MAX6501UKP055+T

Metamorphic switches assert a logic signal after their temperature exceeds a factory-set threshold.

These devices operate from +2.7V to +5.5V temperature sensor MAX6501UKP055+T

Features are two on-chip, temperature-dependent voltage references and comparators. Has factory trimmed temperature trip thresholds from -45°C

To +125°C in 10°C increments and accurate to ±0.5°C (typ) or ±6°C (max). These devices do not require

External components that typically consume 30µA of supply current. Hysteresis is pin selection at 2°C or 10°C. Temperature sensor MAX6501UKP055+T

The MAX6501/MAX6503 have an active low, open drain

The output is intended to interface with a microprocessor (µP) reset input. The MAX6502/MAX6504 have an active-high, push-pull output intended to directly drive fan control logic. The MAX6501/MAX6502 provide thermal temperature thresholds (+35°C to +125°C) that assert -

when the temperature exceeds the threshold. The MAX6503/MAX6504 provide low temperature

Threshold (-45°C to +15°C) at tem- to assert that the temperature is below the threshold. MAX6501-MAX6504 have 8 standards

temperature versions; contact factory for pricing and availability of non-standard temperature versions.

They can be packaged in 5-pin SOT23 temperature sensor MAX6501UKP055+T

MAX6501-MAX6504 Fully Integrated Temperature

The switch includes two temperature-dependent reference-temperature sensors MAX6501UKP055+T

and a comparator. A quote shows pos-

Another temperature coefficient is the negative temperature sensor MAX6501UKP055+T temperature coefficient (Figure 1)

Which two reference voltages are equal determines

Hysteresis keeps the output from oscillating

The mold temperature is close to the threshold temperature.

The MAX6501/MAX6503 have an active low, open-

The MAX6502/MAX6504 have an active high, push-pull-

placed structures that can sink or source current. Inter Milan-

A power-on reset circuit ensures that the output is

t = +25°C at start-up 50µs state.

The MAX6501-MAX6504 are factory available

Preset temperature thresholds from -45°C to +125°C in

10°C increments. Table 1 lists the available temperatures

Threshold range. The output of the MAX6501/MAX6503 is
