The BQ25890HRTWT is a single-cell Li-Ion/Li-Polymer charger from Texas Instruments' MaxCharge™ series, delivering up to 5 A charge current from a 14 V supply. The I²C interface lets the host adjust charge current, termination voltage, and input current limit dynamically — useful for USB-C power negotiation or thermal throttling.
Sourced per RFQ against your target quantity.
The maximum charge current is 5 A, set via the I²C interface or external resistor. At that current, the thermal design must account for the power dissipation in the pass FET and inductor.
No — Texas Instruments lists it as Active. No PCN or EOL notice has been issued, so it remains suitable for production builds.
