MAX6655/MAX6656  
Dual Remote/Local Temperature Sensors and  
Four-Channel Voltage Monitors  
General Description  
Features  
Three Temperature Channels  
• Two Remote PN Junctions  
• One Local Sensor  
The MAX6655/MAX6656 are precise voltage and  
temperature monitors. The digital thermometer reports  
the temperature of two remote sensors and its own die  
temperature. The remote sensors are diode-connected  
transistors—typically a low-cost, easily mounted 2N3906  
PNP type—that replace conventional thermistors 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 collector  
grounded and its base and emitter available for temperature-  
sensing purposes. The temperature is digitized with 11-bit  
resolution.  
Four Voltage Channels  
• +12V, +5V, +3.3V, +2.5V  
• Three External Monitors  
• One Internal Supply Monitor  
11-Bit, 0.125°C Resolution  
High Accuracy: ±1°C Over +60°C to +100°C  
Temperature Range  
Programmable Under/Over-Threshold Alarms  
Programmable Power-Saving Mode  
No Calibration Required  
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 approximately  
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.

TEMP RANGE  
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 con-  
version rate programmable. The adjustable rate allows  
the user to control the supply current.

Typical Application Circuit appears at end of data sheet.  
Pin Configuration  
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  
system shutdown.
