I found it in the Tape & Reel (TR) package, which comes with everything you need.The package 28-WFQFN Exposed Pad 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.The base part number MAX1909 represents its related parts.As far as the terminations are concerned, there are 28.This battery pack has a voltage of 17.65V Max.The device has 28 pins in total.With maximum charging current, its rating is 4A.Channels are available in a total of 2.Using a 18V battery should be enough to run it.The device you are looking at belongs to the subcategory of Power Management Circuits.It was determined during the design process that Vsup (maximum supply voltage) should be set to 6mA.If the supply voltage (Vsup) is kept above 8V, the device will be able to operate normally.
