Home | FAQ Search | On an evaluation board there are 2 BU4327g ICs mounted, connected to 1000pF and 3300pF capacitors, using a common 3.3V power supply. For the BU42xx/BU43xx series, the capacitors are used for delay time setting. However, will the tPHL time be affected by a drop in supply voltage? And regarding the tPHL time, after V<sub>DET</sub> detection, switching is performed in how how much time?
