Product details

5A charge current in a 4x4 mm QFN

The Texas Instruments BQ25895MRTWT is a single-cell MaxCharge™ battery charger that delivers up to 5A charge current from a 14V supply maximum. 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.

Package and thermal handling

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.

Lifecycle and supply posture

No official second source or successor is listed for this exact order code.

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.
