Overview

The RT9465 is a switch-mode single cell li-Ion/Li-Polymer battery charger for portable applications. It integrates a synchronous PWM controller and high accuracy voltage regulation. Besides, the charging current is regulated through the integrated sensing MOSFET. The RT9465 optimizes the charging task by using a control algorithm to vary the charge rate via different modes, including fast charge mode and constant voltage mode. The key charge parameters are programmable via the I²C interface. The junction temperature is monitored by ADC. Other features include under-voltage protection, overvoltage protection (including VBAT and VIN side), thermal regulation and MIVR. The RT9465 is available in a WQFN-16L 3x3 package.
