Battery Charge Control: Dedicated ICs vs Microcontrollers
Design How-To  
10/25/2011   3 comments
Microcontrollers can be used to directly control battery charger power conversion circuits. However, microcontroller circuits and firmware are normally more expensive to design and test and often cost more to produce than chargers based on dedicated charge control ICs. Here are the tradeoffs to consider when making a choice between microcontrollers and dedicated charge control ICs for battery charge control.
