  • BQ24735: Six BQ24735 connected together; timing issue causing surge current through BATFET

    TI Thinks Resolved
    Part Number: BQ24735 We are using six instances of the BQ24735 chip to charge six lithium-ion batteries (minimum 10V, maximum 16.8V). The input to all six chargers is a regulated 24V source from an AC-to-DC power supply. The outputs of all six chargers…

  • BQ24735: BQ24735 can not charge

    TI Thinks Resolved
    Part Number: BQ24735 Hi The customer design with BQ24735. When only the adapter (DC 19V6A) is connected, the ACDET measures 2.8V and the system can be powered on. When the lithium battery(3 series cells) is connected, the first 6s is pre-charge, and…
