    TI Thinks Resolved
    Part Number: BQ25619 Hi team, How much current can deliver to SYS when power path is active(no battery condition)? Regards, Jenitt

  • BQ25619: PMID current with input voltage at VBUS

    TI Thinks Resolved
    Part Number: BQ25619 Hi, We want to use the PMID output to feed an external circuit. We understand that when external voltage is applied to VBUS, the device switches from Boost mode to charging mode. 1- We want to know if is there any current limitation…

  • BQ25619: Radiated emissions over limit at higher frequencies

    Part Number: BQ25619 Hello, We are using I2C controlled 1.5-A single cell buck battery charger BQ25619 and the the radiated emissions are over 47dBuV/m. When testing with BQ25619EVM can see similar results, could you please advise if there is anything…
