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.","metaTitle":"BQ24312DSGT Battery Protection IC, 1-Cell Li-ion","metaDescription":"Texas Instruments BQ24312DSGT battery protection IC for 1-cell Li-ion.
