BQ24257RGET Overview
You can find it in the Tape & Reel (TR) package.It is contained in a package named 24-VFQFN Exposed Pad.Mounting type Surface Mount matches the device.If you wish to ensure reliable performance, set the temperature to -40°C~85°C TA.In order to provide its functionality, this device uses an analog IC called POWER SUPPLY MANAGEMENT CIRCUIT.It is necessary to supply the device with Constant - Programmable current in order to charge it.There are related parts for this device under the base part number BQ24257.It contains 24 terminations, so that is how many there are.Batteries pack have 4.44V Max.In addition to Timer, a variety of programmable features are available.A maximum charging current of 2A is recommended.Product functionality is dependent on 24 pins.It appears that there are 1 channels available at this time.There is a possibility that it can be powered by a 5V battery.An input voltage that is equal to 10.5V can be applied to it without any problem.4.44V output voltages can result in high efficiency.In order to operate, an output current of 2A is used.It is capable of functioning at a voltage as low as possible, for example 4.35V 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.In most cases, the maximum supply voltage (Vsup) is set to 5mA.It appears that there is 13mA current flowing through the supply of the gadget at the moment.As a rule of thumb, the supply voltage needs to be set to 6.5V for optimum efficiency.This part has a switching frequency of 3kHz and operates with this frequency.It is important to note that the maximum output supply voltage for this operation must be set to 4.2V.A reduction in maximum output current to 4A occurs during operation.
