Part Number: TPS22971 Hello,
Two kinds of package information are listed in the data sheet. One of the YZP(R-XBGA-N8) in P21, Another of YZP008 in PACKAGE OUTLINE.
Which is correct YZP (R-XBGA-N8) or YZP008? Regards Taichi Nakamura
Part Number: TPS22971 Dear all.
The turn on control calculation is written in 8.3.2 of datasheet. Do you have min/max value of this calculation?

Hi Technocrat,
Schematic looks good to me. I'd like to bring your awareness to TPS22970 or TPS22971 , which are slightly bigger but improved versions of the device - if they work for you.
Thanks,
Patrick
Hi Toshihiro,
We have load switches that can control the rise time to this value. I would recommend going through the product portfolio. http://www.ti.com/power-management/power-switches/load-switches/overview.html
Many of our load switches are…
Part Number: TPS22971 Hi all :)
my customer wants to expand the turn on time, which is speced with a max of 1520µs (bei CT=10000pF)@3.6V.
Would this be possible with increasing CT?
Thank you, kind regards,
Marion
Hi Alan,
Correct, the TPS22961 does not have Thermal Shutdown/Overtemperature Protection.
However, the TPS22971 does have it, which triggers at 170C and de-asserts after 30C hysteresis.
Thanks,
Patrick
Hi Redick,
I don't know where you see 0.6msec. With that one, you could leave SS/TR floating and get a fast startup time. This may still be longer than 30 usec.
I think the best solution is using any DC/DC, followed by a fast load switch. The TPS22971…
Hello Zirui,
A load switch with quick output discharge could work well for your customers needs:
Our price efficient solution: TPS22919
Our lowest Ron solution: TPS22971
If you take a look at the load switch product folder you can find other load…
Hello Hayato-san,
Is there any reason you're specifically using TPS22914C here? I think the best option would be to switch to a device with either a higher current rating, or with an adjustable slew rate (or fixed slow enough to lower inrush current…
