® RT9465 3A Single Cell Li-on Battery Slave Switching Charger General Description 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.
