The BQ296228DSGT is a battery protection IC for lithium-ion packs of 2 to 4 series cells. Its protection function is overvoltage detection.
The BQ296228DSGT comes in an 8-WSON package measuring 2x2 mm. Tape & Reel and Cut Tape options are available.
The BQ296228DSGT is Active per TI's product status. No discontinuation or last-time-buy notice is in effect, so it remains suitable for new designs and production builds.
The BQ296228DSGT supports 2 to 4 series lithium-ion cells. It provides overvoltage protection for each cell in the stack.
No direct pin-compatible replacement is listed in the official records. The BQ79612PAPRQ1 is a different device — it is an automotive-grade battery monitor with SPI/UART interface, functional safety features, and a 1-cell input, not a 2-4 cell overvoltage protector. The BQ2084DBT-V143 is a battery monitor with SMBus interface for 2-4 cells, but it is a monitor, not a dedicated overvoltage protector, and comes in a different package (TSSOP). Neither is a drop-in substitute. Verify your protection requirements before selecting an alternate.
