Description:
   HM5104 is an LED driver chip that uses a touch switch to realize four modes of cyclic conversion: "100% bright - 25% bright - flashing - off". The chip integrates a key input signal detection circuit with anti-shake function, which can detect the touch switch and control the LED to complete the changes of full brightness, 25% brightness and flashing through the touch switch. The SOS mode can be realized by pressing the switch for more than 3s. Multi-function LED drive application can be realized without MCU programming. HM5104 can directly drive 1~5W LED when powered by three dry batteries or one lithium battery.
