A chip to meet all the features of mobile power, cleaner look, less BOM cost, which greatly improved the production efficiency provide D + D- pin compatible with Apple mobile phones and Samsung Tablet PC with integrated high current charging power display , flashlights, load recognition depends on the MCU to achieve the original function without lithium protection IC and MOSFET and any other active devices, which greatly simplifies the design of mobile power output short program does not lock problem DW01 discharge 1A, 2A boost efficiency of 90%, Small to 2.2uH inductance original single LED, "heartbeat light" display LED power, energy consumption reduced by 80% power display with integrated high-power LED flashlight lighting function perfect short-circuit protection, short circuit no fever, since the resumption of lithium over overcharge, over discharge, short circuit automatically shut down to protect the load is removed after the boost, go into standby mode, the no-load standby power 6uA 1A linear charge, and with input overvoltage protection overcharge, over discharge, output short circuit protection, short-circuit self-recovery charging circuit protection touch switch inputs: Standby - button once - Boost On - / battery indicator on - load 20 seconds - Automatic Standby boost on - button once - Flashlight lights - power display Off - button once - Flashlight off / power display open; after repeated Xiangxi more information, please contact Miss Long: 18565879459
