Juan,
The TPS3890 will be great assuming you are okay with switching to an open-drain /RESET output. It is a very low Iq device and the delay can be adjusted from 40us up to 30s. If you need a push-pull /RESET output, I recommend the TPS3896 as it supports…
Yoko,
Please see our very hand TI Supervisor and Reset IC:
www.ti.com/.../slyt361d.pdf
If you look in the programmable delay section,
1. TPS3890, TPS3895/97, TPS3896/98 all fit that application. TPS3895/97, TPS3896/98 come in fixed and adjustable…

My customer has a question:
I’m looking at TI supervisor ICs and found TPS3895,96,97,98 series. I need what I think is an active HIGH output (open drain or push-pull would work)…
Max,
Yes, we have several devices that do exactly that. My recommendation is TPS3890. You can also use TPS3808, TPS389x (TPS3895, TPS3896, TPS3897, TPS3898). These devices differ in output type (active low/active high, open drain/push pull) and if…
Oscar,
Couple things I need to comment on.
1. TPS3890 is not in the TPS389x family (TPS3895, TPS3896, TPS3897, TPS3898). Sorry for the confusion there.
2. 6.5V max rating is for the SENSE pin. This means you can detect any voltage so long as…
Hi Vasanthan,
You can calculate this from the charging pin current range and a few other factors.
We actually have a calculator for this one that we made for another customer question:

Hi Guy Yater,
Thanks for the response.
When I was going through http://www.ti.com/lit/sg/sszb130b/sszb130b.pdf this document & I found recommended part as TPD8E003.
So now I'm in confusion to use any one of them, Can you please suggest me , which…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
