TPS22976: TPS22916N alternative for high current setup

Part Number: TPS22976
Other Parts Discussed in Thread: TPS2116, TPS2121, TPS22953, TPS2120

Hi,

In releation to this thread:

https://e2e.ti.com/support/power-management/f/power-management-forum/939957/tps22976-equivalent-part-with-no-body-diode

We are looking for a similar solution and was initially exploring using the TPS22976, but understands the issues related to this.

The proposed solution with a dual setup of the TPS22916N sounds promising, but we need a load switch with above 3.5A continious current.

Is there a similar solution, supporting the higher current requirement?

Thanks.

  • Hi User,

    In the time since that post, we have prototyped a new Power MUX device. The TPS2116 is a low voltage powerMUX (voltage rail selector) that takes two inputs and supplies one output. Unfortunately, this device is only rated for 2.5A but integrates all features like reverse current blocking, channel to channel conduction prevention and so on.

    I think an option may be TPS22953 but please note that the reverse current protection for this part only works when the device is disabled (EN low). If your voltages is higher than 2.6V, you may also look into using TPS2121.

  • Hi Shreyas,

    Thank you for your reply. The TPS2116 seemed like a good candidate, but unfortunately the current rating is too low.

    We did have a look at the TPS2121, unfortunately the SEL pin is not available on this component, but only on the TPS2120. This does, however, not have high enough current rating.

    Is there other options?

    Thanks

    /Peter

  • Hi Peter,

    Please take a look at TPS22953. I think this is a good candidate and it does meet specification. If you are okay with a device that only does reverse current blocking when disabled, this should work for you in a MUXing topology.

  • Thanks Shreyas, we willl try it out.

    Appriciate the assistance.

    /Peter
