Question: I am designing a small portable device and using a TPA2036D1 amplifier. My application requires that I detect the case where the amplifier shuts down due to overload (over current). Do you have any suggestions?
Answer: Since switching period of the amplifier is 4uS and it is shutdown for approximately 40uS, simply design a missing pulse detector. There is, in theory, a 10 to 1 ratio between the switching period and the shutdown period; however, it will take the amplifier 3 to four cycles of overload to sense the condition and shutdown. Still there is adequate time to sense shutdown with a simple analog missing pulse detector.
