Description

The MAX6509HAUK+T from Analog Devices is a precision digital temperature switch designed for system-level thermal management. It integrates a temperature-sensing element, ADC, and a user-programmable comparator with an open-drain output. The device triggers its output when the measured temperature exceeds a factory-set or user-programmed threshold, providing a simple, reliable signal for fan control, system shutdown, or overtemperature alarms.

Operating from a 2.7V to 5.5V supply, this sensor is compatible with a wide range of logic levels and is suitable for battery-powered and industrial applications. Its SOT-23-5 package offers a minimal footprint for space-constrained PCB designs, while its -40°C to +125°C operational range ensures reliability in harsh environments.

Key Features

  • Precision temperature sensing with ±0.5°C accuracy (typ.) over the full range.
  • User-programmable temperature trip point via external resistor or factory preset.
  • Open-drain output (THERM) can sink up to 10mA, compatible with multiple logic families.
  • Low-voltage operation from 2.7V to 5.5V, ideal for 3.3V and 5V systems.
  • Compact SOT-23-5 surface-mount package for high-density PCB layouts.
  • Extended industrial temperature range from -40°C to +125°C.
  • Simple 2-wire interface (VCC, GND, THERM) for easy integration.
  • Low power consumption for energy-sensitive monitoring applications.

Applications

  • System-level thermal monitoring and overtemperature protection in embedded computing.
  • Fan speed control and thermal management in power supplies and industrial controllers.
  • Battery temperature monitoring and protection in portable and handheld devices.
  • Environmental temperature sensing in HVAC and building automation systems.
  • Temperature trip-point monitoring in automotive and harsh-environment electronics.

Frequently Asked Questions

What is the output type of the MAX6509HAUK+T sensor and how do I interface with it?

The MAX6509HAUK+T features an open-drain digital output (THERM pin). This output actively pulls low when the measured temperature exceeds the programmed trip point, and is high-impedance otherwise. You must connect a pull-up resistor (typically 10kΩ) from the THERM pin to your logic supply voltage (VCC or another voltage up to 5.5V) to read a valid logic-high signal.

How is the temperature trip point programmed on this IC?

The MAX6509HAUK+T trip point can be factory-set to a specific temperature (indicated by the part number suffix) or user-programmed using an external resistor connected between the SET and GND pins. Refer to the Analog Devices datasheet for the precise resistance-to-temperature mapping. Without an external resistor, the device uses its internal factory-programmed threshold.

What is the operating voltage range and is it compatible with 3.3V microcontroller systems?

Yes, the MAX6509HAUK+T operates from a wide supply voltage range of 2.7V to 5.5V, making it directly compatible with both 3.3V and 5V logic systems. Its open-drain output can be pulled up to any voltage within this same range, ensuring seamless interfacing with your microcontroller's GPIO pins.
