The MAX6642ATT94T from Maxim Integrated is a highly accurate, SMBus-compatible remote and local temperature sensor housed in a 6-pin TDFN package. It features a ±1°C accuracy along with overtemperature alarms, measuring both its own die temperature and remote PN junction temperature—typically a substrate PNP transistor on devices like CPUs, ASICs, GPUs, or FPGAs. The sensor transmits temperature data via a 2-wire serial interface, supporting SMBus commands such as write byte, read byte, send byte, and receive byte, to read temperature data and set alarm thresholds. It includes SMBus timeout for enhanced reliability and reports temperature data in 10-bit resolution, where each LSB equals 0.25°C. The active-low ALERT output signals when temperature thresholds are exceeded. Operating from -40°C to +125°C, it measures remote temperatures between 0°C and +150°C. Additional features include a supply voltage range of 3V to 5.5V, an operational temperature range of -40°C to +85°C, simultaneous dual-zone temperature measurement, programmable thresholds, low measurement latency due to low thermal mass, and a hardwired SMBus/I2C address. The device exhibits a temperature error of ±0.2°C/V supply sensitivity with standby current of 3µA and active current of 0.5mA. Due to market demand, delivery times may be extended and are exempt from discounts.
