The MAX7500–MAX7504 temperature sensors accurately
measure temperature and provide an overtemperature
alarm/interrupt/shutdown output. These
devices convert the temperature measurements to digital
form using a high-resolution, sigma-delta, analog-todigital
converter (ADC). Communication is through an
I2C-compatible 2-wire serial interface. The MAX7500/
MAX7501/MAX7502 integrate a timeout feature that
offers protection against I2C bus lockups. The
MAX7503/MAX7504 do not include the timeout feature.
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 overtemperature shutdown output.
The MAX7500 features three address select lines, while
the MAX7501–MAX7504 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.
The MAX7500–MAX7504 are available in 8-pin μMAX?
and SO packages and operate over the -55°C to
+125°C temperature range.
