MAX6581TG9C+

The MAX6581TG9C+ is a ±1°C accurate 8-channel temperature sensor in 24 pin TQFN package. The MAX6581 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to seven external diode-connected transistors. All temperature channels have programmable alert and overtemperature thresholds. When the measured temperature of a channel crosses the respective threshold, a status bit is set in one of the status registers. Two open-drain alarm outputs assert corresponding to these bits in the status register(s). Resistance cancellation is available for all channels and compensates for high series resistance in circuit-board traces and thermal diodes. The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte and receive byte) for reading the temperature data and programming the alarm thresholds.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from -40°C to 125°C
• Eight channels to measure seven remote and one local temperature
• 11bit, 0.125°C resolution
• High accuracy of ±1°C (max) from +60°C to +100°C (remote channels)
• Measured temperature range from -64°C to +150°C
• Programmable undertemperature/overtemperature alerts
• SMBus/I2C-compatible interface
• Resistance cancellation on all remote channels
