Product details

Single-cell Li-ion charger with integrated protection

The 10-WSON package (3x2 mm) suits space-constrained PCBs in wearables, handheld instruments, and single-cell battery packs.

Charge current and supply headroom

Maximum supply voltage is 10.2 V, which gives margin above the 4.2 V battery target for a 5 V USB rail or a 9 V wall adapter — the linear regulator drops the difference as heat, so the 1 A charge current demands a thermal pad layout to keep junction temperature below the 125°C ceiling.

Surface-mount on a 10-WFDFN exposed-pad footprint.

Frequently asked questions

Does the BQ25050DQCR have overvoltage protection?

Yes, over-voltage protection is included on-chip, along with over-temperature protection. No external comparator is needed.
