MAXIM INTEGRATED / ANALOG DEVICES MAX6639FAEE Temperature Controller

The MAX6639FAEE+ is a dual-channel temperature monitor and PWM fan speed controller in a 16-pin QSOP package. It monitors its own temperature and measures external diode-connected transistors, typically in CPUs, FPGAs, or GPUs. The device features a 2-wire SMBus interface for reading temperatures, programming alarm thresholds, and managing three programmable alarm outputs for interrupts, throttling, or overtemperature shutdowns. It also controls up to two cooling fans via PWM with adjustable frequency up to 25kHz, optimizing cooling noise and efficiency. Operating from 3V to 3.6V, it supports -40°C to +125°C temperature range, with high accuracy of ±1°C for temperature and ±3% for fan speed. It begins temperature monitoring at power-up, ensuring fail-safe operation, with local and remote sensing options, adaptable SMBus addresses, and integrated fault detection for reliable system protection in desktops, notebooks, servers, and projectors.
