I found it in the Tape & Reel (TR) package, which comes with everything you need.The package 8-TFSOJ (0.069, 1.75mm Width) includes a version of it.A Surface Mount mounting type is assigned to the device.If the temperature is set to -40°C~85°C TA, reliable performance will be assured.A analog IC of POWER SUPPLY SUPPORT CIRCUIT has been used in the design of this device.Device charging requires Constant - Programmable current.As far as the terminations are concerned, there are 8.With maximum charging current, its rating is 500mA.You need 8 pins for it to work.Channels are available in a total of 1.Using a 5V battery should be enough to run it.As long as the supply voltage is 7.5V, it is capable of withstanding the voltage.Using a 4.2V output voltage results in high efficiency.There is a constant output current of 500mA when it is operating.If the supply voltage (Vsup) is kept above 4V, the device will be able to operate normally.
