High Efficiency Solar MPPT Battery Charger Using LT8611 and AD5245

Perry Faubert - FAE Jul 10th 2017
Introduction Outdoor applications that use solar panels in the range of a few watts often use a microcontroller-based MPPT (Maximum Power Point Tracking)  function to extract the maximum power available over the full range of environmental operating conditions. Many microcontroller-based MPPT solutions designed for ...

Wireless Current Sense Circuit Floats with Sense Resistor

Kris Lokere - Strategic Applications Manager Apr 25th 2017
Introduction Measuring the current that flows through a sense resistor seems easy. Amplify the voltage, read it with an ADC, and now you know what the current is. But it gets more difficult if the sense resistor itself sits at a voltage that is very different from system ground. Typical solutions bridge that voltage difference ...

High-Voltage Amplifier Extends Coulomb Counter Range to +/-270V

Kris Lokere - Strategic Applications Manager Jan 22nd 2016
Introduction A coulomb counter can measure charge that flows into or out of a battery. Small, dedicated devices such as LTC2941 or LTC2943 can directly interface with low to medium battery voltages, up to about 20V. You can extend the input operating range of the measurement circuit by using a high-voltage amplifier as a level ...

Techniques to Maximize Solar Panel Power Output

Trevor Barcelo - Product Line Manager - Battery Management Feb 3rd 2014
Two recent articles, "Energy Harvesting With Low Power Solar Panels" and  "Solar Battery Charger Maintains High Efficiency at Low Light", discuss how to efficiently harvest energy with low power solar panels. Both of these articles mention a concept known as maximum power, which in the context of solar panels is the ability ...
