The MAX6654 is a precise digital thermometer that reports the temperature of both a remote P-N junction and its own die. The remote junction can be a diode-connected transistor that replaces conventional thermistors or thermocouples. The 2-wire serial interface accepts standard System Management Bus (SMBus)TM commands to program the alarm thresholds and to read temperature data. Measurements can be done automatically and autonomously, with the conversion rate programmed by the user, or programmed to operate in a single-shot mode. The adjustable conversion rate allows the user to optimize supply current and temperature update rate to match system needs.
The MAX6654 is a precise digital temperature sensor that measures both a remote diode‑connected transistor and its own die. It communicates via a 2‑wire SMBus/I²C‑compatible interface and offers programmable alarm thresholds, conversion‑rate control, and optional parasitic resistance cancellation for high‑accuracy measurements.
Typical applications include workstations, test and measurement equipment, desktop and notebook computers, servers, and thin clients. The device is supplied in a 16‑pin QSOP surface‑mount package and is designed for easy integration into thermal‑management systems.
