1-cell Li-ion protection in a 2x2 mm package
The Texas Instruments BQ24312DSGT is a battery protection IC designed for single-cell Lithium Ion packs. It integrates overcurrent, overtemperature, and over/under-voltage fault protection into one 8-WSON (2x2) package, saving board space in compact portable gear.
Fault protection set — what it covers
The device monitors for overcurrent, overtemperature, and over/under-voltage conditions on the battery line. That covers the three common failure modes in a 1-cell Li-ion design — short-circuit, thermal runaway, and deep discharge or overcharge.
Package and footprint
The pad also serves as the ground connection — layout must match the recommended footprint in the datasheet.
