Product details

The I²C interface lets a host controller set charge current, termination voltage, and safety timer — useful when the charge profile must adapt to battery chemistry or temperature in real time.

1.25 A charge current and fault protection

The constant-current charge phase is programmable via I²C up to 1.25 A. Built-in over-voltage and over-temperature protection shut down the charger if the battery or die exceeds safe limits. The safety timer is also programmable, so a stuck battery or failed thermistor won't leave the charger pumping current indefinitely.

The DSBGA bumps are on a 0.5 mm pitch — a stencil with 0.3 mm aperture and a reflow profile matching the JEDEC MSL-1 rating are recommended for assembly yield.

Frequently asked questions

What is the maximum charge current of the BQ24150AYFFR?

The maximum charge current is 1.25 A, programmable via I²C. The actual current in a design depends on the thermal resistance of the PCB layout — the DSBGA package needs a good ground plane to dissipate the heat from a 1.25 A charge cycle.

What package is the BQ24150AYFFR in?

It comes in a 20-bump DSBGA (20-UFBGA, DSBGA) package, also designated as 20-DSBGA.

Can the BQ24150AYFFR charge a 2-cell battery?

No. The device is designed for single-cell Li-Ion/Polymer batteries only (1 cell). The maximum battery pack voltage is 4.44 V, which matches a single-cell termination voltage. For 2-cell packs, look at a multi-cell charger from the BQ2415x family.
