1 Introduction

Besides the common charger parameters such as the input voltage range, the battery charge voltage limit, the maximum charging current, the package size and so on, a single-cell charger designer needs to consider system-level architecture including but not limit to the input current limit detection scheme, the system control methodology, the system monitoring and protection scheme and boost mode operation.
