The ACP1263/ACP1263D is a general USB power switch with 0.4A to 2.5A programmable current limiting to protect the power source from over current and short circuit damage. It also integrates the over temperature protection. If the die temperature exceeds +150°C, thermal shutdown active to shut off the output MOSFET. Until the die temperature drops to +130°C, The output MOSFET then start turn onagain. Otherwise the ACP1263D individually hasbuilt-in discharge function to release the output capacitorcharge at the moment of shutdown. The devices also canblock the current flowing from the output to theinput in case of the output is pulled higher thanthe input voltage under the shutdown. Other featuresinclude input under voltage lockout and soft start functions.The device is available in common SOT25 package.
