Part Details
- Eight Channels to Measure Seven Remote and One Local Temperature
- 11-Bit, 0.125°C Resolution
- High Accuracy of ±1°C (max) from +60°C to +100°C (Remote Channels)
- -64°C to +150°C Remote Temperature Range
- Programmable Undertemperature/Overtemperature Alerts
- SMBus/I²C-Compatible Interface
- Two Open-Drain Alarm Outputs (Active-Low ALERT and Active-Low OVERT)
- Resistance Cancellation on All Remote Channels
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 (active-low ALERT and active-low OVERT) 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.
The MAX6581 is specified for an operating temperature range of -40°C to +125°C and is available in a 24-pin, 4mm × 4mm thin QFN package with an exposed pad.
