TVS2200: In TPS65988/65987, we suggest customer to add TVS diode on VBUSx, could we suggest customer to replace their original part instead by TVS2200?

Hi Sir,

As the title, customer are using the original part with Amazing Microelectronic TVS "AZ2015-01H", could we replace it instead by TVS2200?

Please help to review it and share us some comments.

You can find their datasheet on their website: http://www.amazingic.com/english/01_products/AZ2015-01H

Thanks,

Hello,

Yes you can use TVS2200 and with it's flat clamp it will be able to clamp[ the voltage on the Vbus to a safe level for the TPS65988

Hi Sir,

Thanks for your confirmation, but how about their original TVS parts "AZ2015-01H", is it meet our TPS65988 TVS requirement?

Thanks,

George

Hi George,

The TVS2200 and AZ2015-01H are different devices that would be used in different system architectures. The AZ2015-01H has a breakdown voltage between 6V - 9V while the TVS2200 have a breakdown voltage between 24.6V - 27.6V.

What is the max voltage that is expected on VBUS? Is it greater than 20V? If so than the AZ2015-01H will not work. If the expected voltage is only 5V, then the TVS2200 is not the best device in comparison to the AZ2015-01H, and you should instead recommend the TVS0500
