12-bit local temp sensor with I²C bus interface
The MAX6626PMTT+T is a digital local temperature sensor from Analog Devices, outputting 12-bit temperature data over an I²C-compatible serial interface. It is suited for embedded systems that require a direct digital temperature readout without an external ADC. This meets the typical requirement for thermal monitoring in industrial and telecom equipment where the sensor sits on the same PCB as the heat source. The I²C bus voltage must match the supply rail or use a level translator if the host controller runs at a different voltage.
Package, features, and board integration
Housed in a 6-WDFN with exposed pad (6-TDFN 3x3 mm), the package provides a low thermal resistance path from the die to the PCB copper plane. Built-in features include an output switch, programmable temperature limit, and shutdown mode. The programmable limit can be set via I²C to assert an interrupt or trigger a system shutdown when the temperature crosses a threshold. Surface-mount mounting is standard for high-volume production.
Lifecycle and compliance status
RoHS3 compliant, meeting the latest EU restriction of hazardous substances directive. No additional compliance documentation (REACH, UL, IEC) is listed in the available record.
