Dual Input Prioritizers with Built-In Battery Monitoring

Rajesh Venugopal - Sr Design Engr Dec 8th 2016

Selecting the appropriate input supply to power a system with multiple input power sources is not a trivial task. This video discusses challenges associated with the supply selection process, also known as prioritization. The LTC4419 and its features are introduced to show case how the product solves key prioritization challenges to provide a simple, low cost, power efficient solution. Special cases where input sources are rechargeable batteries require backup battery monitoring. The LTC4420, which is designed for these applications, and provides this function and more is introduced. The video concludes with a quick summary of a prioritization application using the LTC4419.
