UCC3957M-4G4 Product Details

UCC3957M-4G4 Overview


It belongs to package 16-SSOP (0.154, 3.90mm Width). This system battery uses an analog integrated circuit (IC) called POWER SUPPLY SUPPORT CIRCUIT. Channels available are 4. Total pins are 16. There is a Tube case packaging. The electrical component must be mounted with Surface Mount. A voltage of at least 5V volts is required on this electric component. There is a space in between this electrical part and Surface Mount. In order for this power management IC to function correctly, the supplied voltage can't exceed 20V volts. There is a possibility of delivering functions Battery Protection. To best deliver its performance, the electronic part should be operated at a temperature of -20°C~70°C TA. In this electrical part, the battery chemistry includes Lithium-Ion. It is imperative to keep this transceiver ic set to 16V at all times. UCC3957 is the family underlying it. SELECTABLE THREE OR FOUR CELL OPERATION, OVERCURRENT PROTECTION can be discovered in the smart tools battery when using it. A maximum of 0.04mA current must be available from the supply (Isup). It can only supply 25mA current.
