... About the external FET, the parasitic Capacitor may cause the gate voltage to change, when the drain voltage is switching. Make sure to leave adequate margin for this IC variation. １０. By STB voltage, BD9217FV are changed to 2 states. Therefore, do not input STB pin voltage between one state and the other state (0.8～ 2.0V). ...
