MAX6650EUB+ Description

Short technical summary and product information.

The MAX6650EUB+ is an integrated circuit from Analog Devices designed for efficient fan speed control. It utilizes an SMBus/I2C-compatible interface to regulate and monitor the speed of 5VDC and 12VDC brushless fans equipped with built-in tachometers.

 

This device automatically adjusts fan speed to a preprogrammed value by regulating the voltage across the fan using an external MOSFET or bipolar transistor. The MAX6650 variant specifically monitors the tachometer output of a single fan. It offers features such as general-purpose input/output (GPIO) pins for additional hardware control, a programmable alert output for fault detection, and a hardware full-on override for software failures.

 

The MAX6650EUB+ operates from a supply voltage of 3V to 5.5V and has an operating temperature range of -40°C to 85°C. It is available in a compact 10-pin μMAX package, making it suitable for space-constrained applications in servers, workstations, desktop computers, networking, and telecommunications equipment.
