| AN55102 presents a Lithium-Ion (Li-Ion) battery charger design, with the smallest, low-cost PSoC® 1 device – CY8C21x23. |
Multiple methods such as, self-modulated voltage reference, pin multiplexing, time multiplexing of resources and code optimization have been used to implement the design in this chip. The charger can be embedded into consumer and home appliances or industrial applications. The production level design can be implemented in an 8-pin CY8C21123 device. The development can be done in CY8C21223 to add the digital communication required for charge monitoring. This application note includes a dedicated PC-based software developed to perform real time charge process monitoring and analysis.
