EV6914DN-00A 10A Ideal Diode for Solar Panel Bypass The Future of Analog IC Technology DESCRIPTION FEATURES The MP6914 is an ideal diode for solar panel bypass application. It integrates a 30V, 5.5mΩ power MOSFET which will be turned on to conduct a current up to 10A when the corresponding photovoltaic panel is shaded to act as a consuming load. When the shade is released and the panel starts to produce energy, the MOSFET will be turned off. The power loss can be significantly reduced with the MP6914 due to its low voltage drop and low reverse leakage current. The part is available with SOIC8-EP package. Integrated 5.5mΩ 30V Power Switch Very Low Reverse Leakage Current Rugged Design for Long Lifetime SOIC8-EP APPLICATIONS Bypass diode for photovoltaic panels All MPS parts are lead-free and adhere to the RoHS directive.

The photovoltaic battery should have a load within 0-10A range. If a power supply is used to simulate the photovoltaic battery, Vb+ and Vb- should be connected to the power with current limited to absolute value 0-10A, regardless of the port polar. Assume the latter method used to evaluate MP6914: 1. Preset the VDD power supply between 6V and 24V, and turn off the power supply. 2. Connect the positive and negative terminals of the VDD power supply to the VDD and GND pins on the board, respectively. 3. Connect the photovoltaic battery emulate power to Vb+ and Vb-, regardless of the polar. If connect the pos. of emulate power to Vb+ and the neg. of emulate power to Vb- to simulate a solar panel in normal work, the internal MOSFET will be turned off. If connect the pos. of emulate power to Vb- and the neg. of emulate power to Vb+ with current limited to 0-10A to simulate a shaded solar panel which consumes energy from other solar panels, the internal MOSFET will be turned on. 4. Turn on the VDD power supply. NOTICE: The information in this document is subject to change without notice.
