General Description
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 I
2
C
-compatible 2-wire serial interface. The
MAX7500/MAX7501/MAX7502 integrate a timeout fea-
ture that offers protection against I
2
C bus lockups.
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 I
2
C-
compatible interface make them ideal for a wide range
of applications, including personal computers (PCs),
electronic test equipment, and office electronics.
The MAX7500/MAX7501/MAX7502 are available in 8-
pin μMAX
and SO packages and operate over the
-55°C to +125°C temperature range.
