MAX6616 Datasheet Dual-channel Temperature Monitors And Fan-speed Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3713; Rev 2; 10/08 .. Dual-Channel Temperature Monitors and Fan-Speed Controllers with Thermistor.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX6615/MAX6616 monitor two temperature channels, either the internal die temperature and the temperature of an external thermistor, or the temperatures of two external thermistors.

The temperature data controls a PWM output signal to adjust the speed of a cooling fan, thereby minimizing noise when the system is running cool, but providing maximum cooling when power dissipation increases.

The fans’ tachometer output signals are monitored by the MAX6615/MAX6616 to detect fan failure.

Key Features

  • six GPIOs to provide additional flexibility. All of the GPIOs power-up as inputs, with the exception of GPIO0, which powers up as either an input or an output as determined by connecting the PRESET pin to ground or VCC. The MAX6616 is available in a 24-pin QSOP package, while the MAX6615 is available in a 16-pin QSOP package. Both devices operate from a single-supply voltage range of 3.0V to 5.5V, have operating temperature ranges of -40°C to +125°C, and consume just 500µA of supply current. o T.
