TPS2051C: Control signal input when no VIN

Part Number: TPS2051C
Other Parts Discussed in Thread: TPS65132S

Dear team,

When there is no VIN, is the input/output of the control signal(EN,FLT) possible?
Please teach me the rough value if the current has a limit.

Regards,
PAN-M

  • Hi Pan,

    1. What's the meaning of control EN/FLT?

    As without VIN, both pins won't work.

    2. it's 0.85A typical value. Please refer to section 7.7 Ios.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.

  • Hi,

    Is there the problem even if I input a signal into EN and FLT when VIN is not supplied?
    (VIN=0V, EN=High or Low, FLT=pull-up)
    I get an answer to be less than 5mA before in TPS65132S.
    I want to confirm even this device.
