Maxim Integrated MAX6699UE38+ Precision Quad Digital Temperature Sensor
The MAX6699UE38+ from Maxim Integrated is a high-accuracy, quad-channel digital temperature sensor, designed to provide precise temperature monitoring for a variety of applications. This sensor is an ideal solution for systems that require multiple temperature readings, such as computer servers, telecommunications equipment, and industrial control systems.
With its four precision sensors, the MAX6699UE38+ can monitor its own temperature as well as the temperature of three external diode-connected transistors. This feature allows for comprehensive thermal management within a system, ensuring that all critical components are operating within their specified temperature ranges.
The MAX6699UE38+ offers a wide temperature measurement range, typically from -40°C to +125°C for the local sensor and -40°C to +150°C for the remote diode sensors, with an accuracy of ±1°C between +60°C to +100°C. The remote sensors are capable of detecting the temperature of any P-N junction diode with a 1.008V bandgap, such as low-cost, substrate PNP transistors, making it a versatile component for thermal monitoring.
This temperature sensor communicates over a two-wire SMBus/I²C-compatible serial interface, which allows for easy integration into existing systems. The MAX6699UE38+ also features programmable overtemperature alarms and hysteresis settings, which can be configured to alert the system in the event of overheating, thereby protecting the system from thermal damage.
The device is available in a compact, 16-pin QSOP package, making it suitable for space-constrained applications. The MAX6699UE38+ operates over a supply voltage range of 3.0V to 5.5V, providing flexibility in power supply design. Additionally, it includes an SMBus timeout feature for improved system safety in case of bus communication problems.
Overall, the Maxim Integrated MAX6699UE38+ is a reliable and precise temperature sensor that offers advanced features for comprehensive system temperature monitoring, ensuring optimal performance and protection for electronic systems.
