MAX6660 Datasheet (Maxim Integrated) - Remote Junction Temperature Controlled Fan Speed Regulator

MAX6660, Remote Junction Temperature Controlled Fan Speed Regulator

The MAX6660 is a remote temperature sensor and fanspeed regulator that provides a complete fan-control solution.

The remote temperature sensor is typically a common-collector PNP, such as a substrate PNP of a microprocessor, or a diode-connected transistor, typically a low-cost, easily mounted 2N390
