... BD4154FV ●Notes for Use 1.Absolute maximum ratings Although quality is rigorously controlled, the device may be destroyed when applied voltage, operating temperature, etc. exceeds its absolute maximum rating. Because the source (short mode or open mode) cannot be identified once the IC is destroyed important to take physical safety measures such as fusing when implementing any special mode that operates in excess of absolute rating limits ...
