BQ2057CTSTR Overview
I found it in the Tape & Reel (TR) package, which comes with everything you need.To make it easier for you, it is included with the 8-TSSOP (0.173, 4.40mm Width) package.Device mounting type Surface Mount is specified.The temperature should be set to -20°C~70°C TA to ensure reliable performance.This device makes use of an analog IC of POWER SUPPLY SUPPORT CIRCUIT.Providing Constant - Programmable current to the device is the only way to charge it.This part number BQ2057 can be used to find its related parts.It contains 8 terminations, so that is how many there are.Pins 8 are included.There are various programmable features, such as Current.This product requires that a total of 8 pins be connected in order for it to work correctly.It appears that there are 1 channels available at this time.It should be able to run off a battery of 5V.As long as the supply voltage is 15V, it is capable of withstanding the voltage.In the case of 4.2V output voltage, there is a possibility of optimal efficiency.When the operation is completed, the output current is 2A.Devices in this category are classified as Power Management Circuits.Using a supply voltage as low as 4.5V will allow it to function.Vsup (maximum supply voltage) is set in the command to 4mA.Input voltage minimum is 4.5V volts, which is a requirement of the device.
