Product Description

The MPT612, a dedicated IC for performing the Maximum Power Point Tracking (MPPT) function, is designed for use in applications that use solar photovoltaic (PV) cells or in fuel cells. To simplify development and maximize system efficiency, the MPT612 is supported by a patent-pending MPPT algorithm, an application-specific software library and easy-to-use application programming interfaces (APIs). Dedicated hardware functions for PV panels, including voltage and current measurement and panel parameter configuration, simplify design and speed development.

The MPT612 is based on a low-power ARM7TDMI-S RISC processor that operates at up to 70 MHz and can achieve system efficiency ratings up to 98 %. It controls the external switching device through a signal derived from a patent-pending MPPT algorithm. The DC source can be connected to the IC through appropriate voltage and current sensors. The IC dynamically extracts the maximum power from the DC source, without user intervention. The IC can be configured for boundary conditions set in software. Up to 15kB of flash memory is available for application software.
