MAX6665 Overview
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 bees active and powers the fan. The MAX6665 is available with factory-programmed fan activation threshold temperatures from +40°C to +70°C in 5°C increments.
