TPS2051C: Control signal input when no VIN

PAN-M

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.

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.
