Features & Applications

The OM13007,598 is a high-performance MPT612 IC reference board.

The MPT612, the first 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.


  • ARM7TDMI-S 32 bit RISC core operating at up to 70 MHz
  • 128-bit wide interface and accelerator enabling 70 MHz operation
  • 10-bit ADC providing
    • Eight analog inputs
    • Conversion times as low as 2.44 μs per channel and dedicated result registers minimize interrupt overhead
    • Five analog inputs available for user specific applications
  • One 32-bit timer and external event counter with four capture and four compare channels
  • One 16-bit timer and external event counter with three compare channels
  • Low power Real-Time Clock (RTC) with independent power supply and dedicated 32 kHz clock input
  • Serial interfaces including:
    • Two UARTs (16C550)
    • Two Fast I2C-buses (400 kbit/s)
    • SPI and SSP with buffering and variable data length capabilities
  • Vectored interrupt controller with configurable priorities and vector addresses
  • Up to twenty eight (28), 5 V tolerant fast general purpose I/O pins
  • Up to 13 edge or level sensitive external interrupt pins available
  • Three levels of flash Code Read Protection (CRP)
  • 70 MHz maximum clock available from programmable on-chip PLL with input frequencies between 10 MHz and 25 MHz and a settling time of 100 ms
  • Integrated oscillator operates with an external crystal at between 1 MHz and 25 MHz
  • Power saving modes include:
    • Idle mode
    • Two Power-down modes; one with the RTC active and with the RTC deactivated
  • Individual enabling/disabling of peripheral functions and peripheral clock scaling for additional power optimization
  • Processor wake-up from Power-down and Deep power-down mode using an external interrupt or the RTC


  • DC application charge controller for solar PV power and fuel-cells. The use cases are
    • Battery charging for home appliances such as lighting, DC fans, DC TV,DC motor or any other DC appliance
    • Battery charging for public lighting and signaling - LED street lighting, garden/driveway lighting, railway signaling, traffic signaling, remote telecom terminals/towers etc
    • Battery charging for portable devices
  • DC-DC converter per panel to provide improved efficiency
  • Micro inverter per panel removes the need for one large system inverter
