Home|FAQ Search| For the BU48xx/BU49xx/BD48xx/BD49xx series, is continuous operation possible even with the introduction of instantaneous surge waveforms?
For the BU49xx series with CMOS output, the output will be based on the surge voltage, while in the BU48xx series with open drain output the pull-up voltage will be output continously. Regarding the reaction time in response to surges, please refer to the reference data for tPHL and tPLH on page 5 of the technical notes.
