MAX6602

Five-Channel Precision Temperature Monitor

Highly Accurate, Space-Saving, Multichannel Temperature Sensor


Please check latest availability status for a specific part variant.

Description

The MAX6602 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to four external diode-connected transistors. All temperature channels have programmable alert thresholds. Channels 1 and 4 also have programmable overtemperature thresholds. When the measured temperature of a channel exceeds the respective threshold, a status bit is set in one of the status registers. Two open-drain outputs, active-low OVERT and active-low ALERT, assert corresponding to these bits in the status register.

The 2-wire serial interface supports the standard system management bus (SMBus™) protocols: write byte, read byte, send byte, and receive byte for reading the temperature data and programming the alarm thresholds.

The MAX6602 is specified for a -40°C to +125°C operating temperature range and is available in a 16-pin TSSOP package.
