Frequently Asked Questions
How many lithium-ion cells can the BQ24304DSGRG4 protect simultaneously?
The BQ24304DSGRG4 protects 1 lithium-ion cell at a time as a single-channel protection IC, integrating overcharge, overdischarge, and overcurrent detection functions in a single 8-pin SON package, reducing external component count in single-cell battery pack designs.
What package does the BQ24304DSGRG4 use and what advantage does it offer for board layout?
The BQ24304DSGRG4 uses an 8-pin SON (S-PDSO-N8) leadless package with a 0.08 mm pitch and a SOLCC8 equivalence code, providing a very small PCB footprint of approximately 2 mm × 2 mm that is ideal for thin lithium-ion battery pack PCBs in wearables and mobile devices.
Is the BQ24304DSGRG4 suitable for designs requiring RoHS compliance?
Yes, the BQ24304DSGRG4 is fully Pb-free and RoHS-compliant per JESD-609 e4 code with a plastic/epoxy package body, meeting global environmental regulations for consumer electronics and industrial products sold in European and Asian markets.
In what scenarios is the BQ24304DSGRG4 preferred over a discrete MOSFET-based protection circuit?
The BQ24304DSGRG4 integrates all Li-Ion cell protection functions into a single 8-pin IC, eliminating the need for 2 to 4 discrete MOSFETs and resistors, lowering BOM cost and reducing assembly complexity for high-volume single-cell battery pack production runs.
