The present invention provides a general purpose controller chip that can be used for remotely monitoring and/or controlling plurality of devices that require current and/or voltage adjustment. In an embodiment, the general purpose controller chip is capable of performing multiple algorithmic functions such as monitoring current and voltage, adjusting and controlling them, switching power, performing detection algorithms, such as arc detection, LED dimming and the like, as well as communication functions. The general purpose controller chip provides a significantly higher level of integration and thereby makes the design of the devices simpler and dramatically reduces the cost of implementation, while providing ease of maintenance.
