UC3909NG4 Product Details

UC3909NG4 Overview


There is a package called Tube that contains this item.An included version of it is available in the package 20-DIP (0.300, 7.62mm).In this case, the device is mounted in the way of Through Hole.Ensure reliable performance by setting the temperature to 0°C~70°C TA.This device makes use of an analog IC called BATTERY CHARGE CONTROLLER in order to provide its functionality.To charge the device, a current of Constant - Programmable is required.It is possible to find the related parts of this device by looking at its base part number UC3909.As you can see, it has 20 terminations in it.A total of 20 pins are present on it.There are 20 pins required in order for the product to function.In theory, it should be able to run on a battery that has a voltage of 15VV.With a 40V supply voltage, it is capable of withstanding the operation of the device.A device of this type will have its output current set to 2A in this case.This device is classified as Power Management Circuits under the subcategory.A power supply voltage as low as 7.5V can be used for it and it will work as well as possible.There is 19mA voltage set in Vsup (maximum supply voltage).When it comes to the part's power supply, it is set to 15V.The device has 15V voltage input at the moment.As far as switching frequency is concerned, the part runs at 242kHz.As a result of the reduction in maximum output current, the output current should be kept below 4.5mA during operation.
