Digital Temperature Sensors and Thermal  
Watchdog with Bus Lockup Protection  
General Description  
Features  
The MAX7500/MAX7501/MAX7502 temperature sen-  
sors accurately measure temperature and provide an  
over-temperature alarm/interrupt/shutdown output.  
These devices convert the temperature measurements  
to digital form using a high-resolution, sigma-delta, ana-  
log-to-digital converter (ADC). Communication is  
through an I2C-compatible 2-wire serial interface. The  
MAX7500/MAX7501/MAX7502 integrate a timeout fea-  
ture that offers protection against I2C bus lockups.

ꢀ µMAX, SO Packages Save Space  
The 2-wire serial interface accepts standard write byte,  
read byte, send byte, and receive byte commands to  
read the temperature data and configure the behavior  
of the open-drain over-temperature shutdown output.  
The MAX7500 features three address select lines, while  
the MAX7501 and MAX7502 feature two address select  
lines and a RESET input. The MAX7500/MAX7501/  
MAX7502s’ 3.0V to 5.5V supply voltage range, low  
250µA supply current, and a lockup-protected I2C-  
compatible interface make them ideal for a wide range  
of applications, including personal computers (PCs),  
electronic test equipment, and office electronics.
