Maxim Integrated's MAX6659 Precision Temperature Sensor

The MAX6659 from Maxim Integrated is a highly accurate, low-voltage temperature sensor designed for a variety of applications that require precise temperature monitoring. This sensor is capable of measuring the temperature of both its own die as well as two external diode-connected transistors, making it ideal for monitoring the temperature of CPU cores, chipset components, or other critical system parts.

With its wide temperature measurement range of -40°C to +125°C for the local sensor and -40°C to +150°C for the remote diode-connected transistors, the MAX6659 ensures versatility across different operating environments. Its accuracy is impressive, with ±1°C accuracy for the local sensor and ±3°C for the external sensors, providing reliable data for system management and protection.

The device operates from a supply voltage of 3.0V to 5.5V, making it suitable for use in low-voltage systems and battery-powered applications. Additionally, the MAX6659 features programmable overtemperature alarms and two-wire serial interface compatible with I²C and SMBus protocols. This allows for easy integration into existing systems and provides the flexibility needed for various design requirements.

Another notable feature of the MAX6659 is its low power consumption, which is critical for maintaining energy efficiency in portable devices. The sensor also includes a shutdown mode that further reduces power usage when temperature monitoring is not required, thus extending battery life in mobile applications.

The MAX6659 is available in a small, 8-pin µMAX package, which is ideal for space-constrained designs. Its compact footprint and low profile make it an excellent choice for modern electronics where board space is at a premium.

Overall, the MAX6659 temperature sensor is an excellent choice for engineers looking to integrate precise temperature monitoring into their systems. Its accuracy, versatility, and low power consumption make it well-suited for a range of applications including personal computers, office electronics, industrial controls, and portable devices.
