Other Parts Discussed in Thread: TPS40170

Customer will control TPS40170's Enable for Reset IC (SVS) High/Low output.

But VDIS of TPS40170 is too low(100mV), I didn't find match Reset IC.

Is there recommended SVS parts for match VDIS threshold?

Or originally, can't Enable-pin connect to Reset IC for reasons of TPS40170 spec?

Any update on this?

I think that there is no match SVS device, and better solution is SVS-output to UVLO-input, is it correct?

Best regards,

Hi Sotashi,

Sorry for late reply. Can you consider to use a FET to control TPS40170 EN pin?
When FET is turn on, the TPS40170 EN pin can be pulled lower than 100mV.

Thanks
Qian
