BQ2057TS Overview

I found it in the Tube package, which comes with everything you need.We've included it in the 8-TSSOP (0.173, 4.40mm Width) package so that it's easier to use.Mounting type Surface Mount matches the device.It is recommended to set the temperature to -20°C~70°C TA for reliable performance.In order to provide its functionality, this device uses an analog IC called POWER SUPPLY SUPPORT CIRCUIT.Charge the device by providing it with Constant - Programmable current.This device's related parts can be found under the base part number BQ2057.There are no terminations in it at all.It is a 4.1V voltage for the battery pack.There are 8 pins on the circuit board.There are several programmable features, such as Current.For the product to work properly, 8 pins must be connected in order to make it work.There are a total of 1 channels available for your use.A battery with 0V would be enough for it to run.In order for the device to operate properly, the supply voltage should not exceed 15V.There is a possibility of achieving optimal efficiency when the output voltage of the device is 8.2V.It is performed with a current output of 2A for the output of the operation.This device belongs to the subcategory of Power Management Circuits.This device can work at as low a voltage as possible, such as 4.5V.4mA is set for Vsup (maximum supply voltage).The input voltage is set to 4.5V volts.During this operation, the maximum output supply voltage should be 8.2V.
