Overview
Description
The Renesas ISL81601-US011REFZ solar battery charger board with MPPT uses energy from a solar panel (user-provided) to charge a standard 12V lead acid battery. The MPPT software maximizes the power drawn from the solar panel, and the RL78/G14 microcontroller (MCU) controls the output voltage to follow a safe charging profile for the lead acid battery.
The ISL81601-US011REFZ reference boards are designed to provide a quick and easy method for creating a solar battery charger using the ISL81601 buck-boost controller, RL78/G14 MCU, ISL80410 linear regulator, and ISL28413 quad operational amplifier.
Features
- The MPPT algorithm maximizes the power drawn from the solar panel
- Integrated protection features include overcurrent, over-temperature, over/undervoltage, and reverse polarity protection
- VIN: 8V to 40V
- VOUT: Bulk charge = 14.5V at up to 7A
- Float mode = 13.6V at <= 0.7A
- Useful in battery-powered industrial applications
