Lithium-ion battery protection in a 2x2 mm package
The Texas Instruments BQ24315DSGT is a dedicated battery protection IC for single-cell Lithium Ion packs. It integrates overcurrent, overtemperature, and over/under voltage fault protection into an 8-WSON (2x2) package, making it a fit for space-constrained portable designs where discrete protection would consume more board area.
Fault protection set and temperature range
The BQ24315DSGT monitors the battery for overcurrent events (short-circuit or excessive load), overtemperature conditions, and over/under voltage thresholds.
