LTC2947 ±30A Power/Energy Monitor with Integrated RSENSE - Video Product Brief

Chris Gobok - Product Marketing Engineer Sep 8th 2016


The LTC2947 is a high-precision power and energy monitor with an internal sense resistor supporting up to ±30A. Three internal No Latency Δ∑™ ADCs ensure accurate measurement of voltage and current, while highbandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.

An internal 300µΩ, temperature-compensated sense resistor minimizes efficiency loss and external components, simplifying energy measurement applications while enabling high accuracy current measurement over the full temperature range.

All measured quantities are stored in internal registers accessible via the selectable I2C/SPI interface. The LTC2947 features programmable high and low thresholds for all
