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.
