... BD2204GUL *3 When the switch changes from VIN1 to VIN2 or from VIN2 to VIN1 possible that VOUT voltage drops. Dropped voltage of VOUT is specified as Voutdrop1 and Voutdrop2. That voltage drop is caused by the function which prevents VIN1 and VIN2 from turning on simultaneously. This function generates the period which both VIN1and VIN2 are turned off, and prevents the penetration current between VIN1 and VIN2. VOUT=VIN2→ ...

... BD2204GUL ●Operational Notes (1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc ...
