What this part does and where it fits
The Texas Instruments BQ296100DSGT is a dedicated over-voltage protection IC for 2-to-4-cell series lithium-ion battery packs. It monitors each cell and triggers a fault output when any cell exceeds the over-voltage threshold — no fuel-gauging, no SMBus communication, just a hardwired protection latch. The part sits on the BMS board between the cell stack and the pack's discharge FET, typically paired with a separate battery monitor or gauge IC that handles cell balancing and state-of-charge reporting.
Package and reflow considerations
The BQ296100DSGT comes in an 8-WSON (2x2) package. The exposed pad requires a solid thermal land and proper stencil aperture.
