General Description
The MAX7500MAX7504 temperature sensors accu-
rately measure temperature and provide an overtem-
perature alarm/interrupt/shutdown output. These
devices convert the temperature measurements to digi-
tal form using a high-resolution, sigma-delta, analog-to-
digital converter (ADC). Communication is through an
I
2
C-compatible 2-wire serial interface. The MAX7500/
MAX7501/MAX7502 integrate a timeout feature that
offers protection against I
2
C 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 MAX7501MAX7504 feature two address select
lines and a RESET input. The MAX7500/MAX7501/
MAX7502s 3.0V to 5.5V supply voltage range, low
250礎 supply current, and a lockup-protected I
2
C-com-
patible interface make them ideal for a wide range of
applications, including personal computers (PCs), elec-
tronic test equipment, and office electronics.
The MAX7500MAX7504 are available in 8-pin 礛AX

and SO packages and operate over the -55癈 to
+125癈 temperature range.
