BQ24278YFFT Overview
This item can be found in the Cut Tape (CT) package.The 49-UFBGA, DSBGA package includes it as a convenience.The mounting type of the device is Surface Mount.If you wish to ensure reliable performance, set the temperature to -40°C~85°C TA.In order for this device to function, it utilizes an analog integrated circuit called POWER SUPPLY SUPPORT CIRCUIT.To charge the device, there is a requirement for Constant - Programmable current.With the base part number BQ24278, it is possible to find related parts.Taking it as a whole, it has been concluded that there are 49 terminations to be found.Batteries have a voltage of 3.7V.It operates on the basis of 49 pins.Currently, there are 1 available channels.As their maximum supply voltage, devices require 10V.Batteries with 5V can be used to power it.It is important that the supply voltage does not exceed 10.5V for the device to work properly.High efficiency can be achieved with a 4.2V output voltage.It is performed with a current output of 2.5A for the output of the operation.A supply voltage of 4V is suitable for it, because it can operate with a low supply voltage.I'd like to emphasize that the mounting of the device is done in the same manner as Surface Mount.The part has 1.5MHz switching frequency.
