The Analog Devices MAX6501UKP045+T is a micropower, factory-trimmed temperature switch IC in a SOT-23-5 package. It provides an open-drain, active-low output that triggers when the die temperature exceeds its preset +45°C threshold, making it ideal for overtemperature protection in 3.3V or 5V systems.

Features

  • Factory-programmed +45°C (±0.5°C) switching threshold
  • Micropower consumption for battery-sensitive applications
  • Open-drain, active-low output (active when hot)
  • Wide -55°C to +125°C operating temperature range
  • Compact SOT-23-5 surface-mount package

Description

The MAX6501UKP045+T is a precision, low-power temperature switch designed for system monitoring and protection. It integrates a temperature-sensing element, a precision comparator, and an open-drain output stage. The device is factory-calibrated to trigger its output when the die temperature rises above +45°C, with a high accuracy of ±0.5°C at the setpoint.

Its micropower operation and simple digital output make it suitable for integration into space-constrained designs requiring reliable thermal management, such as in power supplies, embedded computing modules, and battery packs. The wide operating range ensures functionality in harsh industrial environments.

Key Features

  • Precision factory-trimmed temperature switch with ±0.5°C accuracy at setpoint
  • Ultra-low power consumption for always-on monitoring
  • Open-drain output (active-low /OverTemp) can sink up to 20mA
  • Robust performance across a -55°C to +125°C temperature range
  • Industry-standard SOT-23-5 package for easy PCB assembly
  • Simplifies thermal protection circuitry without external components
  • High-value build for critical overtemperature detection

Applications

  • Overtemperature protection and shutdown in DC-DC converters and power modules
  • Thermal monitoring in embedded systems, SBCs (Raspberry Pi, Arduino), and FPGA boards
  • Battery pack temperature sensing and safety cutoff
  • Environmental monitoring within sealed industrial enclosures
  • Fan control activation based on system temperature

Frequently Asked Questions

What is the switching temperature of the MAX6501UKP045+T?

The MAX6501UKP045+T is factory-programmed with a fixed switching threshold of +45°C. When the die temperature exceeds this setpoint, the open-drain output activates (goes low). The accuracy at this specific temperature is ±0.5°C.

How do I connect and use the open-drain output?

The open-drain output requires an external pull-up resistor to your logic supply voltage (e.g., 3.3V or 5V). When the temperature is below the setpoint, the output is high-impedance (pulled high). When the temperature exceeds +45°C, the output actively pulls the line to GND, signaling an overtemperature condition.

What is the operating voltage range for this temperature switch?

While the specific supply voltage (Vcc) range should be confirmed in the datasheet, devices in this family typically operate from 2.7V to 5.5V. The open-drain output voltage is determined by the external pull-up resistor's supply rail, allowing interface with 3.3V or 5V logic systems.

Can this sensor be used for continuous temperature measurement?

No, the MAX6501UKP045+T is a temperature switch, not a thermometer. It provides a digital on/off signal based on a single factory-set threshold. For continuous analog or digital temperature readings, a different sensor like a thermistor or I2C temperature sensor IC would be required.
