MAX1669 Datasheet (Maxim) - Fan Controller and Remote Temperature Sensor with SMBus Serial Interface

MAX1669, Fan Controller and Remote Temperature Sensor with SMBus Serial Interface

The MAX1669 fan controller includes a precise digital thermometer that reports the temperature of a remote sensor.

The remote sensor is a diode-connected transistor *typically a low-cost, easily mounted 2N3906 PNP type *replacing conventional thermistors or thermocouples.

MAX1669 Features

* include general-purpose inputs/outputs (GPIOs) for fan presence detection and a thermostat output intended as a fan override signal in case the host system loses the ability to communicate. The internal ADC has a wide input voltage range and gives overrange readings when too large an input voltage i
