General Description
The MAX6655/MAX6656 are precise voltage and tem-
perature monitors. The digital thermometer reports the
temperature of two remote sensors and its own die tem-
perature. The remote sensors are diode-connected
transistors—typically a low-cost, easily mounted
2N3906 PNP type—that replace conventional thermis-
tors or thermocouples. Remote accuracy is ±1°C for
multiple transistor manufacturers with no calibration
necessary. The remote channels can also measure the
die temperature of other ICs, such as microprocessors,
that contain a substrate-connected PNP with its collec-
tor grounded and its base and emitter available for tem-
perature-sensing purposes. The temperature is
digitized with 11-bit resolution.
The MAX6655/MAX6656 also measure their own supply
voltage and three external voltages with 8-bit resolution.
Each voltage input’s sensitivity is set to give approxi-
mately 3/4-scale output code when the input voltage is
at its nominal value. The MAX6655 operates at +5V
supply and its second voltage monitor is 3.3V. The
MAX6656 operates on a +3.3V supply and its second
voltage monitor is 5V.
The 2-wire serial interface accepts standard SMBus
Write Byte, Read Byte, Send Byte, and Receive Byte
commands to program the alarm thresholds and to
read data. The MAX6655/MAX6656 also provide
SMBus alert response and timeout functions. The
MAX6655/MAX6656 measure automatically and
autonomously, with the conversion rate programmable.
The adjustable rate allows the user to control the supply
current.
In addition to the SMBus ALERT output, the MAX6655/
MAX6656 feature an OVERT output, which is used as a
temperature reset that remains active only while the
temperature is above the maximum temperature limit.
The OVERT output is optimal for fan control or for sys-
tem shutdown.
