Hi Delaney,
I believe you are looking for some form of UVLO. Unfortunately, TPS22990 does not have integrated UVLO like devices such as TPS22810, TPS22953 and TPS22954.

Part Number: LM3881 Hi Team,
My customer is planning on using our LM3881 to power the enable pin of the TPS22954 . A concern of my customer is that the TPS22954 may turn on due to the Vflag votlage ramping up as it's input voltage ramps as well as seen in the…
Part Number: TPS22917 Other Parts Discussed in Thread: TUSB1210 , TPS22953 , TPS22954 , TPS22951 I am using the TUSB1210 with a Zynq XC7Z010. There is good information on sequencing the 1.8V rail for VDD18 and VDDIO after VBAT/VDD33, which is the opposite…
Hi Helen,
Thanks for your quicky reply.
Please see the below measurement result for one of these NG boards.
The EN is from TPS22954 PG (power good) open-drain pin and it is pulled up to TPS61089 Vin by 100K ohm.
So EN is almost the same as Vin with slightly…
Hi Zhengquan,
What is the voltage and current levels in this application? What kind of UVLO control is needed?
Off the top of my head I would suggest taking a look at TPS22953 and TPS22954 which implement a UVLO similar to TPS22810.
You can also look…
