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.

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.

ꢀ Separate OpenꢂDrain OS Output Operates as

Interrupt or Comparator/Thermostat Input

ꢀ Register Readback Capability
