overview

1. Purpose

<p class="MsoNormal">The RT9468 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for portable applications. It integrates a synchronous PWM controller, power MOSFETs, input current sensing and regulation, high-accuracy voltage regulation, and charge termination. The charge current is regulated through integrated sensing resistors. The RT9468 also features USB On-The-Go (OTG) support. The RT9468 integrates an easy-to-use direct charge function, simply driving an external MOSFET to enable a direct charge path, as well as over-voltage protection, over-current protection, and watchdog functions. This document explains the function and use of the RT9468 evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to suit individual requirements.</p>
