UCS1002 AND PIC16F1503 REFERENCE DESIGN

This UCS1002 and PIC16F1503 Reference Design is a fully functional universal serial bus (USB) charger compatible with a large variety of portable devices. The UCS1002 programmable port-power controller can deliver up to 2.5A charging current. Features like current monitoring and programmable charger emulation profiles make it a good candidate to be used with a PIC® Microcontroller for intelligent USB charging solutions. The algorithm implemented in the PIC microcontroller applies multiple charger emulation profiles and selects the one that provides the highest current to the attached device. For more information regarding the code, refer to AN1827 – "UCS1002 Highest Current Algorithm Using a PIC® Microcontroller” (DS20001827A). The board can be powered from 5V directly or through the MCP16323 Synchronous Buck Regulator which allows 6-18V input.
