MAX6651EEE+T

The MAX6651EEE+T is a fan speed regulator and monitor with SMBus/I2C compatible interface in 16 pin QSOP 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 fan’s tachometer frequency 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 MAX6651 regulates the speed of a single fan but it contains additional tachometer inputs to monitor up to four fans and control them as a single unit when they are used in parallel. The device provides GPIO pins that serve as digital inputs, digital outputs or various hardware interfaces. The MAX6651 is used in RAID servers, workstations, networking and telecommunication applications.
