Product details

What the MAX6642ATT90+T does on the board

The MAX6642ATT90+T is a digital temperature sensor from Analog Devices that measures its own die temperature and, via an external diode-connected transistor, a remote hot spot. 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.

Frequently asked questions

What is the closest pin-compatible alternative to MAX6642ATT90+T?

Within the MAX6642 family, density variants share the same 6-TDFN footprint and SMBus interface. 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.

Is MAX6642ATT90+T compatible with 3.3V logic?

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.

What are the key features of the MAX6642ATT90+T?

Key features include One-Shot conversion, an output switch for overtemperature alert, programmable limit registers, and a standby mode that drops supply current. These make it suited for periodic temperature polling in battery-powered or thermally constrained systems.
