Linear's LTC2995 high accuracy temperature and dual voltage monitor

Linear Technology Corporation has introduced the LTC2995 high accuracy temperature sensor and dual supply monitor for low voltage systems.

The LTC2995 provides a voltage proportional to absolute temperature (VPTAT) output, as well as individual under temperature, over temperature, under voltage and over voltage alert outputs defined by user adjustable thresholds. No code is required to configure the device. The LTC2995 combines the functionality of a temperature monitor and dual voltage monitor in a space-saving, micropower solution.

The LTC2995 is suitable for applications such as system thermal control, energy harvesting, desktop and notebook computers, network servers and environmental monitoring.

The LTC2995 draws 220µA of supply current over the full operating temperature range.
The device is offered in commercial, industrial and automotive versions, supporting operating temperature ranges from 0°C to 70°C, -40°C to 85°C and -40°C to 125°C, respectively.
