  • BQ2002: For PVD, does it operate as "VBAT is lower than any previously measured value by 0mV~5mV, then fast charge is terminate"?

    TI Thinks Resolved
    Part Number: BQ2002 Hi team, Datasheet says; For PVD (TM = low or mid), a decrease of 2.5mV ±2.5mV terminates fast charge . The PVD and -∆V tests are valid in the range 1V < VBAT < 2V. Does it mean that "VBAT is lower than any previously measured…

  • BQ2002: Lower Charge Current

    Part Number: BQ2002 Hi team, What are the concerns when charging NiMH with bq2002 at 0.1C? Will it not be possible to detect full charge? Best Regards,
