At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. SI4840DY-Y1-E3 on stock Power-Down Mode During a rapid power-down condition,as would occurwith a power-supply short circuit orwith a poorlyfiltered power supply, the energy stored in Cx could discharge into Pin 2 or 14. To avoid possible device damage in this mode, when Cx is > 0.5 microfarad, a protection diode with a l-ampere or higher rating (1N5395 0r equivalent) and a separate ground return for Cx should be provided as shown in Fig. Panasonic is endeavoring to continually improve the quality and reliability of these materials but there is always the possibility that further rectifications will be required in the future. Therefore, Panasonic will not assume any liability for any damages arising from any errors etc. that may ap- pear in this material. |
