Description:
   HM5110 is a 5-function LED lighting driver chip controlled by a touch switch, especially suitable for LED headlights. It uses a very small SOT23-6 lead-free package and a capacitor device, which saves both PCB space and system cost. Three dry batteries or one lithium battery can drive 1-6W LED. HM5110 realizes function selection through a touch switch.

FEATUREs:
✦ Power on OFF, after light touch, L1L3 lights up and L2L3 lights up
✦ L1L2L3 lights up at the same time and L1L2L3 flashes at the same time, all three lights go out
✦ Working voltage: 2.5V~5V
✦ Working efficiency up to 93%
✦ 120mΩ low on-resistance
✦ L1, L2 both have 1.4A driving current capability
✦ L3 has the effect of indicator light
✦ SOT23-6 green package
✦ Touch the button to achieve function selection
