Semtech has introduced the SX8743, an expansion of its low-power temperature sensing and monitoring platform, which can monitor up to four temperature zones in servers, advanced printers, appliances, and other complex systems. This 8pin device combines one integrated temperature sensor with monitoring electronics to directly connect up to three external temperature diodes. It is suitable for systems with multiple ASICs, hard drives or other heat sources, which need to be monitored for safe operation during normal and sleep modes. The device drives the sensing diodes with a variable current and converts that into digital temperature information. The device can connect to discrete diodes or transistors to monitor the temperature of air flow or active mechanics like hard drives. It can autonomously set or reset alarms if the sensor temperature exceeds programmed thresholds.
