Part Number: TPS22942 The referred thread is from 5 years ago.
The current datasheet is from August 2021.
The datasheet only mentions Top Markings (BJ, BN).
Why did TI not update the Top Markings to all four in the version August 2021 of the datasheet? …

Hi Mo,
As per the datasheet, TPS22942 has a current limit of 100mA.TPS2294 1 has a current limit of 40mA. Can you confirm which exact device you are using?
Thanks.
Regards Ankush
Kevin,
The specification shows a minimum current limit of 100mA. You are correct that the typical value is higher than that. However, the typical value can not be guaranteed across all conditions.

Other Parts Discussed in Thread: TPS22942 My customer asks:
We are having issues with the TPS22942 not turning on. It seems that when the device is first powered up there is a current draw that causes the over-current pin to trip. We read this OC on our…
Hi Vikas,
The only issue you may find is that the TPS22942 does not block reverse current when it is turned off. Therefore, if you had a higher output voltage than input voltage, current would flow from VOUT to VIN through the body diode. If the TPS22942…
This probelm was solved by adding a current limit controller to the CC1101 power input. Part used was TPS22942. When the CC1101 latches up it starts to draw excessive current >100ma. The current limit controller interupts power for 80 ms which resets…
