Overview
19-2225; Rev 0; 10/01 Remote-Junction Temperature-Controlled Fan-Speed Regulator with SMBus Interface General Description The MAX6660 is a remote temperature sensor and fanspeed regulator that provides a complete fan-control solution.
The remote temperature sensor is typically a common-collector PNP, such as a substrate PNP of a microprocessor, or a diode-connected transistor, typically a low-cost, easily mounted 2N3904 NPN type or 2N3906 PNP type.
The device also incorporates a closed-loop fan controller that regulates fan speed with tachometer feedback.
The MAX6660 compares temperature data to a fan threshold temperature and gain setting, both programmed over the SMBus™ by the user.
