MAX6665 Fan Controller/Driver with Factory- Programmed Temperature Thresholds

The MAX6665 is a fully integrated thermal switch with an internal power transistor for driving a cooling fan rated up to 24V and 250mA. When the MAX6665’s temperature rises above a factory-programmed threshold, the FANOUT pin becomes active and powers the fan. The MAX6665 is available with factory-p.

MAX6665 Features

* can be used to safely power down systems that are overheated. The MAX6665 operates from a +2.7V to +5.5V power supply, and the associated fan can be powered from 4.5V to 24V. It is available in an 8-pin SO package and operates from -40°C to +125°C. o On-Chip 250mA Fan Switch o No External Components
