3-to-6 cell Li-Ion protection in a 16-TSSOP
The Texas Instruments BQ77PL157APW-4225 is a battery protection IC designed for Lithium Ion/Polymer packs with 3 to 6 series cells, monitoring for over-voltage faults across the stack.
Sourcing and lifecycle: active, single-source
For BOM risk mitigation, the BQ296217DSGT covers a different cell count (2 to 4) and comes in a smaller 8-SON package, which would require a board layout change.
