For our wrist watch project we have selected "bq51050B"  wireless charger chip to charge 3.7V  160mAh battery, could you please share me any reference schematic with proper current limiting resistor. Let me know I have selected right part or not ?, hope this chip is capable to charge 160mAh battery. As per data sheet its shows minimum charge current limit is 500mA, let me know how to charge 160mAh battery

    Hello

    The BQ51050B is designed for higher charge currents, at lower charge currents the regulation accuracy decreases.

    A better solution for 160mAh would be BQ51003 and BQ25100, see TIDA-00318.  The BQ25100 will support low charge current.
