>Designed to simplify board-level energy measurements, the LTC2947 power and energy monitor for 0V to 15V DC supply rails eliminates the need for an external sense resistor to measure current. by Graham Prophet @ edn-europe.com

Choosing a sense resistor, Linear says, is not an easy task, especially when dealing with high currents, where available sense resistors can dissipate too much power, occupy a lot of board space or have a large impact on measurement accuracy. The LTC2947 integrates a 300 µΩ temperature-compensated sense resistor to alleviate these concerns, providing users with a simple 24 mm² solution that provides up to 1.2% accurate energy readings at up to ±30A.
