It reports both readings over an SMBus interface at 10-bit resolution. The part integrates a One-Shot conversion trigger, a programmable limit with an output switch, and a standby mode for power-sensitive designs. Accuracy is rated ±2°C typical, ±3°C worst-case over the full range — tight enough for thermal monitoring of a processor die, power module, or battery cell. ## Sourcing and lifecycle Listed as Active with ROHS3 compliance.","metaTitle":"MAX6642ATT90+T Digital Temp Sensor, SMBus, 10-bit, 6-TDFN","metaDescription":"MAX6642ATT90+T digital temperature sensor from Analog Devices.

The key difference is the programmed temperature threshold and conversion rate. For a direct drop-in, verify the threshold setting matches your application; otherwise, the family is pin-compatible across the ATT90, ATT85, and other suffix options."},{"question":"Is MAX6642ATT90+T compatible with 3.3V logic?","answer":"Yes. The supply range of 3V to 5.5V includes 3.3V, and the SMBus interface operates at the supply voltage. No level shifter is needed when the host controller also runs at 3.3V."},{"question":"What are the key features of the MAX6642ATT90+T?","answer":"Key features include One-Shot conversion, an output switch for overtemperature alert, programmable limit registers, and a standby mode that drops supply current.
