Product details

5A charge current in a 4x4 mm QFN

The I²C interface lets the host controller adjust charge voltage, current, and termination thresholds on the fly — useful for adaptive charging profiles or thermal throttling in tight enclosures.

Housed in a 24-WFQFN Exposed Pad package (4x4 mm body), the BQ25895MRTWT relies on the exposed thermal pad for heat sinking.

USB and I²C interface support

The USB interface handles standard 5V bus power, while the 14V input ceiling covers higher-voltage adapters. I²C programmability allows the system to set charge current, battery regulation voltage, and input current limit — enabling compliance with USB BC1.2 or proprietary fast-charge protocols.

Frequently asked questions

What is the charge current of BQ25895MRTWT?

The maximum charge current is 5A, programmable via the I²C interface. Actual charge current in a design depends on the input source capability, thermal budget, and battery impedance.

Does BQ25895MRTWT support USB Type-C?

The USB interface is compatible with standard USB power sources, but the part does not integrate USB Type-C configuration channel (CC) logic. For Type-C applications, an external CC controller or PD PHY is needed to negotiate the power contract before the charger sees VBUS.

What is the difference between BQ25895MRTWT and BQ25890?

The BQ25895 is a variant within the same MaxCharge™ family. The key difference is the charge current ceiling: the BQ25895 is rated for 5A max, while the BQ25890 is limited to 3A. Both share the same 24-WQFN package and I²C interface, but the higher current rating of the BQ25895 requires more careful thermal design. Pin compatibility should be verified against the respective datasheets before substitution.
