I found it in the Tape & Reel (TR) package, which comes with everything you need.The package 20-SOIC (0.295, 7.50mm Width) includes a version of it.A Surface Mount mounting type is assigned to the device.If the temperature is set to 0°C~70°C TA, reliable performance will be assured.A analog IC of BATTERY CHARGE CONTROLLER has been used in the design of this device.Device charging requires Constant - Programmable current.The base part number UC3909 represents its related parts.As far as the terminations are concerned, there are 20.The device has 20 pins in total.You need 20 pins for it to work.Using a 15V battery should be enough to run it.As long as the supply voltage is 40V, it is capable of withstanding the voltage.There is a constant output current of 100mA when it is operating.The device you are looking at belongs to the subcategory of Power Management Circuits.The device can operate at as low a supply voltage as possible, such as 7.5V.It was determined during the design process that Vsup (maximum supply voltage) should be set to 19mA.A power supply setting of 0 has been assigned to the part.There is 15V voltage input on the device.242kHz switching frequency is used by the part.
