Introduction

AI Translation

SE9017 is a complete constant-current & constant voltage linear charger for single cell lithium-ion and Lithium-Polymer batteries. Its SOT - 23 package and low external component count make SE9017 ideally suited for portable applications. Furthermore, the SE9017 is specifically designed to work within USB power specification. At the same time, SE9017 can also be used in the standalone lithium-ion and Lithium-polymer battery chargers.
