Overview
19-2056; Rev 0; 5/01 Fan Controller/Driver with FactoryProgrammed Temperature Thresholds General Description 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-programmed fan activation threshold temperatures from +40°C to +70°C in 5°C increments.
Accuracy of the fan activation trip point is ±1°C (typ) and ±3°C (max).
The trip point’s hysteresis is pin selectable to 1°C, 4°C, or 8°C.
Two opendrain logic outputs indicate overtemperature conditions:...
