Product details

It handles charge currents up to 2.5 A, programmable via I²C, and includes fault protection for over-current, over-temperature, and over-voltage conditions. The I²C interface lets a host microcontroller set the charge current, termination threshold, and read status — useful in designs that need dynamic charge profiles or fuel-gauge integration.

The 2.5 A max charge current is the peak the power stage can deliver to a single-cell pack at 4.2 V. That current drives the inductor and MOSFET sizing on the PCB.

The base product number is BQ24195, so any PCN or successor announcements would share that root.

Package and footprint — what to watch on the layout

The VFQFN with exposed pad (4x4 mm body) is a common power-management footprint. Surface-mount only; no through-hole variant exists.

Frequently asked questions

Does BQ24195LRGER support 4.2V battery packs?

Yes — the battery pack voltage is listed as 4.2V, which is the standard full-charge voltage for a single-cell Li-Ion or Li-Polymer pack.

Can BQ24195LRGER charge 2-cell Li-Ion?

No — this charger is designed for a single cell only (Number of Cells: 1). For a 2-cell stack you would need a different charger IC rated for series-cell charging.
