MAX6656MEE-T

The MAX6656MEE-T is a precise digital temperature monitor from Analog Devices, designed for accurate temperature sensing in various applications. It can measure its own die temperature and two remote sensors, typically using low-cost PNP transistors. The device offers an 11-bit resolution for temperature readings, providing high accuracy.

This sensor also features four voltage monitoring channels, with 8-bit resolution, capable of measuring supply voltages and external inputs. The MAX6656 operates on a 3V to 5.5V supply. Communication is handled via a 2-wire serial SMBus/I2C-compatible interface, allowing for easy programming of alarm thresholds and data reading. It includes features like SMBus alert response, timeout functions, and a programmable conversion rate to manage supply current.

For system control, the MAX6656MEE-T provides an OVERT output, suitable for fan control or system shutdown when temperatures exceed limits. It is housed in a 16-QSOP package and supports surface mount installation. The operating temperature range is -55°C to 125°C, with specific accuracy ratings provided for different temperature conditions.

Applications for this sensor include notebooks, thin clients, servers, workstations, communication equipment, and desktop PCs, where reliable temperature monitoring is crucial for performance and system integrity.
