® RT9532 Linear Single Cell Li-Ion Battery Charger IC for Portable Applications General Description The RT9532 is a fully integrated single cell Li-ion battery charger IC ideal for portable applications. The RT9532 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 RT9532, 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 RT9532 can allow 4.2V/2.
