RT9467,PDF数据表下载

RT9467 pdf资料下载The RT9467 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 RT9467 also features USB On-The-Go (OTG) support. RT9467 integrates D+/D- pin for USB host/charging port detection. The RT9467 optimizes for charging task by using a control algorithm to vary the charge rate for different modes, including pre-charge mode, fast charge mode (constant voltage and constant current). The key charge parameters are programmable through an I2C interface. The RT9467 will resume the charge cycle whenever the battery voltage falls below an internal recharge threshold, and can automatically enter sleep mode if the input power supply is removed.Datasheet pdf资料数据表下载
