TPS389C03-Q1: Alternative for MAX20478BATBH/VY+

Part Number: TPS389C03-Q1

Tool/software:

Hi team, 

Would like to check with you if we have P2P alternative for MAX20478BATBH/VY+. If not, please also recommend our non-P2P alternative.

Thanks!

    Hello Ethan, 

    I see the MAX20478 device is a ASIL D multichannel supervisor with watchdog. Currently we have TPS389C03-Q1 released which is a ASILD multichannel supervisor with Q&A watchdog. We are able accommodate multiple channel counts, though we are not directly pin to pin. If a window watchdog is required this will fall under our TPS388C0x-Q1 device, which is ASILB at a device level. 

    1. What is the desired ASIL rating?

    2. What application is this in? 

    Please feel free to email me directly if response contains sensitive information. 

    Regards,

    Hi Oscar, 

    Thanks for the feedbacks. 

    The desired ASIL rating is ASIL-B. The application is the cockpit, and use for monitoring MCU's safety related power rail(2 to 3 rails, 1.2V/1.8V/3.3V). 

    I don't find detailed information/schedule for TPS388C0x-Q1 information in ti.com. May you kindly provide that?
