MAX31760AEE+ Product Details
The MAX31760 integrates temperature sensing along with precision PWM fan control. It accurately measures its local die temperature and the remote temperature of a discrete diode-connected transistor, such as a 2N3906, or a thermal diode commonly found on CPUs, graphics processor units (GPUs), and other ASICs. Multiple temperature thresholds, such as local high/overtemperature (OT) and remote high/overtemperature, can be set by an I2C-compatible interface.
Fan speed is controlled based on the temperature reading as an index to a 48-byte lookup table (LUT) containing user-programmed PWM values. The flexible LUT-based architecture enables the user to program a smooth nonlinear fan speed vs. temperature transfer function to minimize acoustic fan noise. Two tachometer inputs allow measuring the speeds of two fans independently. The FF/FS pin multiplexes an open-drain fan-failure output with a full-speed fan-drive input. When the local or remote OT threshold is exceeded, the SHDN pin is asserted low and can be used to shut down the system. A dedicated ALERT pin reports that either a local or remote hightemperature threshold has been exceeded. ALERT can be programmed to work in either fault indicator mode or interrupt mode. These features make the device a compact and complete solution for a single-fan or two-fan cooling system.
