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. If a fan failure is detected, the active-low FAN_FAIL output is asserted.
The 2-wire serial interface accepts standard system
management bus (SMBus™) write byte, read byte,
send byte, and receive byte commands to read the
temperature data and program the alarm thresholds.
The programmable alarm output can be used to generate
interrupts, throttle signals, or overtemperature shutdown
signals.
The MAX6616 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.
