Frequently Asked Questions
How many lithium-ion cells can the UCC3957MTR-1G4 protect?
The UCC3957MTR-1G4 supports selectable operation for either 3-cell or 4-cell lithium-ion battery packs. A single configuration pin controls the cell count, eliminating the need for separate ICs in multi-SKU battery pack designs.
What protection features does the UCC3957MTR-1G4 include?
The IC provides overcurrent protection for the battery discharge path, preventing cell damage during excessive load events. It also monitors individual cell voltages across up to 4 channels, enabling overvoltage and undervoltage protection to maximize battery longevity and safety.
What package does the UCC3957MTR-1G4 use?
The UCC3957MTR-1G4 is packaged in a 16-pin SSOP (Shrink Small Outline Package) with 0.25-inch body width. This compact package is well suited for integration into slim battery pack PCBs where board space is limited.
Is the UCC3957MTR-1G4 RoHS compliant?
Yes, the UCC3957MTR-1G4 carries a Pb-free (lead-free) designation and is manufactured in compliance with RoHS environmental directives, making it suitable for consumer electronics and other applications with strict hazardous substance restrictions.
