65 A+ Power/Energy Monitor with Integrated Sense Resistor



The LTC2947-65 is a high precision power and energy monitor with an internal sense resistor supporting up to ±65A*. 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 150µΩ, 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 quanities are stored in internal registers accessible via the selectable I2C/SPI interface. The LTC2947-65 features programmable high and low thresholds for all measured quantities to reduce digital traffic with the host.
