LTC4009CUF-2#PBF Overview

There is an Tube package that contains it. It comes as part of the 20-WFQFN Exposed Pad package.Mounting type Surface Mount is chosen for the device.Ideally, the temperature should be set to 0°C~85°C TA in order to ensure reliable performance.The device relies on an analog IC called BATTERY CHARGE CONTROLLER to operate.To charge the device, a current of Constant - Programmable is required.The related parts of the base part number LTC4009 can be found by following the order of the base part number.As a whole, it contains 20 terminations.There is a voltage of 16.8V for the battery pack as well.The device consists of 20 pins, which are arranged in a row.In order for the product to function as intended, there are 20 pins that must be connected.To ensure the device works properly, the supply voltage should not exceed 28V.In the case of 28V output voltage, there is a possibility of optimal efficiency.This device can work at as low a voltage as possible, such as 6V.Amounting is in line with Surface Mount.There is 20V voltage input on the device.As well as the additional features of ALSO OPERATES IN ADJUSTABLE MODE FROM 2V TO 28V, this device can also be used to generate the same functionality.At most, the part has a switching frequency of 633kHz.
