MAX6651 General Description

The MAX6650/MAX6651 fan controllers use an SMBus/I2C-compatible interface to regulate and monitor the speed of 5VDC/12VDC brushless fans with builtin tachometers. They automatically force the fan’s tachometer frequency (fan speed) to match a preprogrammed value in the Fan-Speed Register by using an .
