BQ2057CTS Overview

There is a version of it included in the package Tube.The 8-TSSOP (0.173, 4.40mm Width) package includes it as a convenience.Mounting type is Surface Mount.The temperature should be set to -20°C~70°C TA to ensure reliable performance.In order for this device to function, it utilizes an analog integrated circuit called POWER SUPPLY SUPPORT CIRCUIT.In order to charge the device, it needs to receive Constant - Programmable current.If you use the base part number BQ2057, you can look for related parts.There are no terminations in it at all.Due to the 8 pins on it, it is a very simple circuit.The unit is equipped with a number of programmable features, including Current.In order for the product to function as intended, there are 8 pins that must be connected.The number of channels available is 1.Power can be provided by a battery with 5V.With a 15V supply voltage, it is capable of withstanding the operation of the device.In the case of 4.2V output voltage, there is a possibility of optimal efficiency.A device of this type will have its output current set to 2A in this case.This device is a member of subcategory Power Management Circuits.A power supply voltage as low as 4.5V can be used for it and it will work as well as possible.During the design process, Vsup (maximum supply voltage) was set to 4mA.There is a 4.5V volt minimum input voltage requirement.
