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 ...



30A Power and Energy Monitor with Integrated Sense Resistor

Aug 29th 2016
With more and more importance attributed to reduce energy consumption, power monitoring at various points of a system becomes mandatory. Precise power monitoring requires to measure the voltage drop over a current sense resistor as alternative concepts such as hall sensors or flux gate suffer from imperfections due to offset ...



Four-Channel PMBus Power System Manager with Input Energy Monitoring for Comprehensive Power System Management

Wayne Porter - Design Engineer Jan 30th 2015
Systems with multiple power rails are becoming more efficient, but increasingly complex and difficult to design. In such systems, operating costs and complexity have shifted the power system design paradigm. To adapt, groups of power supplies need to be controlled and monitored to manage efficiency, to coordinate sequencing, ...



80V Wide Range I2C Power Monitor Simplifies Challenging System Monitoring Tasks

Mark Thoren - Staff Scientist Mar 20th 2013
Accurate monitoring of power is an essential part of a reliable and energy efficient (green) system design. Measuring voltage and current of low voltage (1.8V to 36V) supplies is straightforward, but higher voltages present additional challenges. In this video, we will show the LTC2945 wide range I2C system monitor. This device ...



LTC2990 I2C Temperature, Voltage and Current Monitor - Video Product Brief

Chris Gobok - Product Marketing Engineer Feb 23rd 2011
The LTC2990 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the device can be configured to measure many combinations of internal temperature, remote temperature, remote voltage, remote current and internal VCC. The internal 10ppm/°C reference minimizes the number of supporting ...



LT2940 Power and Current Monitor - Video Product Brief

Kevin B. Scott - Senior Strategic Marketing Engineer Feb 11th 2010
The LT2940 measures a high side current and a differential voltage, multiplies them and outputs a current proportional to instantaneous power. Bidirectional high side currents and bipolar voltage differences are correctly handled by the four-quadrant multiplier and push-pull output stage, which allows the LT2940 to indicate ...
