  • TPS6521825: Does PWR_EN control nPFO?

    Resolved
    Part Number: TPS6521825 Hello TI Forums, On TPS6521825, can anyone confirm if the nPFO signal is controlled by PWR_EN? If PWR_EN is low, does that force nPFO to go low as well? Or is PFI the only pin that controls the state of nPFO? Thanks!
