BQ2057WSNTR Product Details

BQ2057WSNTR Overview


This can be found in the Tape & Reel (TR) package.In the package 8-SOIC (0.154, 3.90mm Width), there is a version of it.Mounting type Surface Mount is chosen for the device.Temperature -20°C~70°C TA is recommended for reliable performance.Using an analog IC of type POWER SUPPLY SUPPORT CIRCUIT, this device is able to communicate with the outside world.To charge the device, you need Constant - Programmable current.Identify its related parts based on the base part number BQ2057.There are no terminations in it at all.8 pins are attached to it.In addition to Current, there are several other programmable options.For it to work, 8 pins are required.Currently, there are 1 available channels.A battery with 0V would be enough for it to run.The board is capable of handling a voltage input of zero volts.A 8.4V output voltage provides high efficiency.It is in this instance that the device's output current is set to 2A.There is one subcategory of this device, and it is Power Management Circuits.At a low supply voltage, such as 4.5V, it can operate to the best of its ability.During the design process, Vsup (maximum supply voltage) was set to 4mA.Input voltage must be at least 4.5V volts in order to function.
