It triggers a fault output when any cell exceeds the over-voltage threshold, giving the system controller or charge FET a signal to interrupt charging. The part is housed in an 8-WFDFN with exposed pad (supplier device package 8-WSON, 2x2 mm), a compact footprint suited for space-constrained battery pack PCBs where board area is at a premium. ## Temperature range and deployment context Rated for -40°C to 110°C ambient, the BQ294702DSGT covers the full operating envelope of consumer, industrial, and some automotive-grade battery packs. The 110°C upper limit provides margin above typical 85°C pack interiors, important when cells are under fast-charge or in a sealed enclosure. Surface-mount assembly on the 8-WSON package follows standard lead-free reflow profiles. Sourcing is confirmed against an RFQ — lead time and pricing are established at quote time, with the BOM quantity as the basis.","metaTitle":"TI BQ294702DSGT Battery Protection IC, 2-4 Cell Li-Ion","metaDescription":"Texas Instruments BQ294702DSGT battery protection IC for 2-4 series Li-ion cells.
