Measurement of a system’s power consumption during a final factory test (before deployment into the field) is a prudent part of a test program for any product. But there is an increasing emphasis to bring this functionality into the product itself for “run-time” monitoring of power, current, supply voltage, ...

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 ...
