Device identity and fault coverage
The BQ24381DSGRG4 is a lithium-ion battery protection IC from Texas Instruments, integrating overcurrent, over-temperature, over/under-voltage, and short-circuit fault protection into a single 8-WSON package.
Supplied in an 8-WFDFN with exposed pad (8-WSON, 2x2 mm), the package requires a thermal land pattern on the PCB to conduct heat from the die to the board plane. Surface-mount assembly with Tape & Reel packaging supports standard pick-and-place and reflow profiles. The small 2x2 mm footprint fits space-constrained battery management circuits on a single-layer or multi-layer board.
The base product number BQ24381 identifies the family; the DSGRG4 suffix denotes the 8-WSON package and Tape & Reel quantity. RoHS compliance is standard for this TI catalog line.
