Frequently Asked Questions
What accuracy does MAX6628MKA+T achieve for remote temperature sensing in server thermal management?
MAX6628MKA+T achieves ±1°C accuracy for remote temperature sensing under typical conditions, with a maximum error of 5.5°C across the full range. This precision is sufficient for implementing fan speed control algorithms and thermal throttle thresholds in server and desktop processor thermal management.
How does MAX6628MKA+T communicate with a host processor for temperature data readout?
MAX6628MKA+T uses an I2C and SMBus compatible 2-wire serial interface, allowing it to share a bus with other I2C peripherals at standard 100 kHz or fast 400 kHz speeds. The device outputs temperature data as a digital word, eliminating the ADC and reference circuitry needed for analog sensor solutions.
For a high-density server blade PCB, how small is the footprint of MAX6628MKA+T?
The 8-pin SOT-23 package of MAX6628MKA+T measures 2.9 mm × 1.62 mm with a body height of 1.1 mm, making it one of the smallest digital temperature sensor options for surface-mount assembly. Multiple sensors can be placed near heat sources on a single 1U server blade without consuming meaningful board area.
Can MAX6628MKA+T monitor the junction temperature of a remote power transistor using its diode interface?
Yes. MAX6628MKA+T is designed to measure temperature through an external diode-connected transistor or the substrate diode of a power device, using a forced-current technique. This allows accurate junction temperature reading of power FETs or IGBTs at distances up to several centimeters, provided the cable capacitance stays below a few hundred pF.
What is the lifecycle outlook for MAX6628MKA+T, and are there recommended second-source alternatives?
MAX6628MKA+T has a YTEOL value of 9, indicating active production status with several years of expected supply. For designs requiring a second source, the LM84 or TMP451 offer comparable ±1°C remote sensing accuracy, I2C interface, and 8-pin SOT-23 packaging with compatible register maps.
