MCP73871T-3CAI/ML Overview

If you are looking for it in the Tape & Reel (TR) package, then you have found it.Located in package 20-VFQFN Exposed Pad, it can be found there.Mounting type Surface Mount matches the device.A temperature setting of -40°C~85°C TA would be the best thing to do.To operate the device, an analog IC called POWER SUPPLY MANAGEMENT CIRCUIT is used.It is necessary to supply the device with Constant - Programmable current in order to charge it.The related parts of the base part number MCP73871 can be found by following the order of the base part number.It has 20 terminations.It is equipped with 20 pins.In addition to the standard features, a number of programmable functions are available to the user, such as Timer.The charging current of the part is 1.1A at maximum.You need 20 pins for it to work.The system currently provides 1 channels for the user to use.In theory, it should be able to run on a battery that has a voltage of 5.35VV.A supply voltage of no more than 6V is required for the device to operate properly.It is possible to achieve optimum efficiency in the case of a given output voltage of 4.35V.Operation is achieved by providing a 1A output current.There is a subcategory of Power Management Circuits for this device.It is capable of functioning at a voltage as low as possible, for example 4.65V voltage for this circuit is used.I'd like to emphasize that the mounting of the device is done in the same manner as Surface Mount.It was determined during the design process that Vsup (maximum supply voltage) should be set to 3.75mA.It is set to 5V when it comes to the power supply for the part.
