[FAQ] TPS659037: TPS6590376ZWSR vs TPS6590378ZWSR

Part Number: TPS659037

Customer is referring to AM5728 EVM schematic & using TPS6590376ZWSR. TPS6590378ZWSR is available & I see three differences between both devices from user guide:

1. GPIO_2 was added to the sequences at the same time as SMPS3

2. SMPS3 moved from slot 3 to slot 2 in power-down sequence

3. The delay between slot 2 and slot 3 in power-down sequence was increased from 500 µs to 1000 µs

Is it advised to use TPS6590378ZWSR device instead of TPS6590376ZWSR ? 

Are both p2p replacements ?

Checking as TPS6590376ZWSR free samples support has been stopped & customer needs samples so can support samples of TPS6590378ZWSR.

Best Regards,

Prahlad

  • Hi Prahlad,

    I have assigned this post to Nastasha, who supports this device directly so please allow for some delay in answering your question as she will not be back until January 3rd.

    Thank you,

  • Prahlad,

    TPS6590378 is pin to pin compatible with TPS6590376. In this newer version (TPS6590378), the power sequence was optimized. It still meets all requirements of the AM572x processors with the added option of GPIO2 being available for enabling external devices if needed.

    I recommend using the TPS6590378 for the samples. There should be no issues transitioning to the newer OTP.


    Thanks,
    Nastasha
