TPS22922: Power Switch - Transistor-Like Device

Part Number: TPS22922

Hi Team,

May I ask for help? My customer want a transistor part number for his application. He want a transistor switch which can be connected to the battery to stop the battery leakage. His battery voltage is 3.3 v.

I am checking TPS22922 if this will be of use for this type of application; but I am not sure. If this wont fit for this application, can you suggest a device that will fit for our customer requirement?

Thank you and regards,

  • Hello Gerald,

    We have numerous devices with very low shutdown currents that would help extend battery life. I've placed two links below- one to our load switch portfolio and another to a technical article that explains a bit more on how load switches can help extend battery life. The device you've mentioned is good; however, it has a larger shutdown current than numerous other devices. As I don't know the other parameters for their system I can't help pick out the best device, but in the product folder you can sort by shutdown current and eliminate the ones that fall outside of your parameters to find the best one for your application.
