RT9536 pdf资料下载The RT9536 is a fully integrated single cell Li-ion battery charger IC ideal for portable applications. The RT9536 optimizes the charging task by using a control algorithm including pre-charge mode, fast charge mode and constant voltage mode. The input voltage range of the VIN pin can be as high as 28V. When the input voltage exceeds the OVP threshold, it will turn off the charging MOSFET to avoid overheating of the chip. In RT9536, the maximum charging current can be programmed with an external resistor. For USB application, the user can set the current to 100mA/500mA through the EN/SET pin. For the factory mode, the RT9536 can allow 4.2V or 4.35V/2.3A power pass through to support system operation. It also provides a 50mA LDO to support the power of peripheral circuit. The internal thermal feedback circuit regulates the die temperature to optimize the charge rate for all ambient temperatures. The RT9536 provides protection functions such as under voltage protection, over voltage protection for VIN supply and thermal protection for battery temperature.Datasheet pdf资料数据表下载
