OM13007

OM13007 is a reference board for photovoltaic MPPT battery charge controller using MPT612 IC . The IC is developed for Maximum Power Point Tracking (MPPT) applications to extract the maximum power from a source such as a PV panel or fuel cell. The ICs primary function is to track the MPP of the source based on the voltage and current. The resulting PWM output is sent to MOSFET to control the device switching, enabling the system to operate at MPP. Utilizing a patent pending MPPT algorithm defined in the embedded software, the MPT612 provides up to 15kB of on chip high speed flash memory enabling enhanced functionality using user software. Serial communication interfaces such as UART, SPI, SSP and I2C bus make the MPT612 ideally suited for integrating with real world systems. MPT612 is based on ARM7TDMI-S 32bit RISC core which operates at up to 70MHz and MPT612 provides a number of standard software libraries for implementing PV MPPT function and several other optional functions.

• 128bit wide interface and accelerator enabling 70MHz operation
• One 32bit timer and external event counter with four capture and four compare channels
• One 16bit timer and external event counter with four compare channels
• Low power RTC with independent power supply and dedicated 32kHz clock input
• Vectored interrupt controller with configurable priorities and vector addresses
• Up to 28, 5V tolerant fast general purpose I/O pins
• Three levels of flash Code Read Protection
• Power saving modes included
• In System/In Application Programming (ISP/IAP) via on chip bootloader software
