MAX6650EUB+T

The MAX6650EUB+T is a fan speed regulator and monitor with SMBus/I2C compatible interface in 10 pin µMAX package. This fan controller uses SMBus/I2C compatible interface to regulate and monitor speed of 5VDC/12VDC brushless fans with built-in tachometers. It automatically forces the fan’s tachometer frequency (fan speed) to match pre-programmed value in fan speed register by using an external MOSFET or bipolar transistor to linearly regulate voltage across the fan. The MAX6650 regulates speed of a single fan by monitoring its tachometer output. The device provides general purpose input/output (GPIO) pins that serve as digital inputs, digital outputs or various hardware interfaces. Capable of sinking 10mA, these open-drain inputs/outputs can drive an LED. The MAX6650 is used in RAID servers, workstations, networking and telecommunication applications.
