Product details

What is the maximum charge current for BQ24161BRGER?

The BQ24161BRGER delivers a programmable charge current up to 2.5 A max for a single-cell Li-Ion or Li-Polymer pack. The current is set via the I²C bus.

Is BQ24161BRGER still in active production?

Texas Instruments is still manufacturing the part and accepting new orders. The 24-VQFN (4x4) package is a current footprint.

Package and interface for layout planning

The BQ24161BRGER is supplied in a 24-VFQFN Exposed Pad package, Tape & Reel (TR) for automated assembly. The 4 mm × 4 mm body includes a thermal pad for heat dissipation. The I²C interface uses two pins (SCL, SDA) for control. The charger's input voltage supply max is 10 V.

Frequently asked questions

How can I order BQ24161BRGER or check current pricing and availability?

The BQ24161BRGER is Active and available through our distribution network. Submit an RFQ with your target quantity and lead-time window; we will confirm pricing and stock availability at quote time. No stock-holding claim is made — availability is confirmed per order.

Does BQ24161BRGER have power path management?

The evidence does not list power path management as a feature. The part provides constant programmable charge current and fault protection for over-temperature and over-voltage, but the presence of dynamic power path (DPPM) is not confirmed in the cited data. Review the full datasheet for system-load support during charging.
