Product details

Single-cell Li-Ion charger with USB interface

It integrates fault protection against over-temperature, over-voltage, reverse current, and short-circuit conditions, reducing external component count on the charge path.

Charge current and thermal design

The 1.5 A maximum charge current is set via an external resistor, and the timer is programmable — useful for tailoring the charge profile to different cell capacities without firmware intervention. The 3×3 mm 16-VQFN package with exposed pad dissipates heat into the PCB copper plane; at 1.5 A continuous charge current, the pad area and thermal vias determine the junction temperature rise, especially above 85°C ambient.

Frequently asked questions

What is the maximum charge current for BQ24074RGTT?

The maximum charge current is 1.5 A, programmable via an external resistor. The constant-current charge phase is set by this resistor; the timer is also programmable.

Is BQ24074RGTT compatible with 4.2 V lithium-ion batteries?

Yes. The battery pack voltage is 4.2 V, matching the standard termination voltage for single-cell Li-Ion cells. The charger terminates when the battery reaches this voltage.

What is the difference between BQ24074RGTT and BQ24075RGTT?

Both are single-cell Li-Ion chargers in the same package and pinout. The BQ24074 uses a USB interface; the BQ24075 typically includes additional features such as power-path management. Confirm the specific BQ24075 variant datasheet for the exact feature delta.
