There is an Tube package that contains it. For convenience, it is included in the 20-WFQFN Exposed Pad package.A Surface Mount mounting type is assigned to the device.The correct temperature setting is 0°C~85°C TA.In order to provide its functionality, this device uses an analog IC called BATTERY CHARGE CONTROLLER.In order to charge the device, it needs to receive Constant - Programmable current.If you use the base part number LTC4009, you can look for related parts.As you can see, it has 20 terminations in it.In the case of the battery pack, it is 16.4V.This board has 20 pins, making it very simple to construct.There is a preference for devices with 28V maximum supply voltages.In the case of 5V, the output voltage is likely to produce high efficiency.20V is the input voltage for the device.Input voltage must be no less than 6V volts.The part's switching frequency is at most 633kHz.This device accepts a maximum input voltage of 28V.
