AN817 A Discrete Approach to Battery Charging

AN817 Vishay Siliconix A Discrete Approach to Battery Charging for Cellular Phones Guy Moxey and Michael Speed INTRODUCTION All portable cordless appliances must receive power from an external source, whether it’s a wall cube adapter, car charger, or docking station. This external source will then charge, in a predetermined fashion, the equipment’s internal battery. In the case of a portable phone, the power management system will incorporate charging control circuitry to regulate the voltage .

AN817 Features

* choice due to its small size and high energy density. Li+ cells are generally suited to a constant-current/constant-voltage charging strategy and although relatively simple to imple
