UCC3957M-2 Overview
A 16-SSOP (0.154, 3.90mm Width) package would be appropriate for this. This device uses an analog IC called POWER SUPPLY SUPPORT CIRCUIT. We have 4 channels available. 16 pins are present on it. Tube cases are used for packaging. The part must be mounted with Surface Mount. There should be a minimum supply voltage of 5V volts for this part. This electrical component is from the Power Management Circuits family. There is a mounting point for this part in the direction of Surface Mount. There should be 20V voltage over 20V volts on the supply to this chip. There is a possibility of delivering functions Battery Protection. For the part to perform properly, it should be operated at temperature -20°C~70°C TA. This part includes Lithium-Ion in its battery chemistry. It is important to keep this device set to 16V at all times. This is a family based on UCC3957. When using this device, SELECTABLE THREE OR FOUR CELL OPERATION, OVERCURRENT PROTECTION can be discovered in the device. Supply current (Isup) must not exceed 0.04mA.
