Part Number: FM2819
Function : LED Control IC
Package: SOT23-6 Type
Manufacturer: SHENZHEN FUMAN ELECTRONICS
This IC is designed for LED miner’s lamp ASIC, using the most advanced control technology and wide voltage design. It can strengthen the durability of IC, can control 3W or 3W the following LED lights, with current limiting protection, over-temperature protection, output short circuit protection, anti-battery reverse function.
Chip by changing the size of the external resistor R1 to change the LED lamp current; through the touch switch button control: bright → dark light → flash, so the cycle; when the long press the button SOS function.
