The BQ24168RGET from Texas Instruments is a single-cell Li-Ion/Polymer battery charger with a 2.5 A maximum charge current and an I²C interface for programmable charge parameters.
Built-in over-temperature and over-voltage fault protection reduce the need for external supervisory circuitry, simplifying the BOM and board area.
The maximum charge current is 2.5 A, programmable via I²C. The actual current the design can sustain depends on the thermal dissipation of the 24-VQFN package and the PCB copper area under the exposed pad.
The evidence does not list USB OTG support. The part is specified as a single-cell Li-Ion/Polymer charger with I²C control and over-temperature/over-voltage protection. For OTG capability, check the BQ24168 family datasheet or consider a dedicated boost/OTG charger variant.
