Product details

What this protection IC covers

The Texas Instruments BQ24351DSGR is a Li-Ion battery protection IC that monitors and protects against overcurrent, over-temperature, over/under voltage, and short-circuit faults. It is designed for single-cell lithium-ion battery packs in portable equipment where a compact, integrated protection solution is needed.

Fault protection set — what it catches

The device integrates four protection functions: overcurrent, over-temperature, over/under voltage, and short-circuit. This means a single chip replaces discrete comparators and sense resistors for the battery cell monitoring, shrinking the BOM and board area on a battery management PCB.

Temperature grade and reflow reality

The 8-WSON (2x2 mm) exposed-pad package demands a solder stencil aperture covering at least 50% of the pad area for thermal transfer; check the MSL rating before the reflow profile is locked.

Lifecycle and sourcing posture

No official second source or pin-compatible alternate is documented in the TI cross-reference database, so the BOM should treat this as a sole-source line item.

Frequently asked questions

What is BQ24351DSGR used for?

It is a Li-Ion battery protection IC that guards against overcurrent, over-temperature, over/under voltage, and short-circuit faults in single-cell lithium-ion battery packs.

Does BQ24351DSGR have overcurrent protection?

Yes, overcurrent protection is one of the four integrated fault protections, alongside over-temperature, over/under voltage, and short-circuit.

What is the difference between BQ24351DSGR and BQ24350DSGR?

The BQ24350DSGR is a sibling in the same protection family; the key difference is typically the overvoltage threshold setpoint or enable logic. Check the respective datasheets for the exact trip voltages — the BQ24351DSGR is the variant with a specific threshold tailored for certain cell chemistries.
