Part Number: TPS65981
Other Parts Discussed in Thread: TPS65982, , TPS65987, TPS65982DC

Hello E2E team,

I have two quick questions!

Q1.

Now I'm looking for USB type C PD w integrated SBU, USB MUX & MCU like CYPD5225-96BZXI.

Is there any other part to replace this?

Q2.

I want to figure out differences between TPS65981 and TPS65982.

As I checked the passive switch is a key difference so far. and also I hope to know passive switches role in here too.

Best regard,

Ben Cho

Hi Ben,

Q1: Both TPS65981 and TPS65982 have the SBU/USB mux integrated but not MCU. One note these devices are USB PD2 compliant, we have TPS65987/88 which are PD3 compliant but it doesn't have the mux integrated.

Q2: If you need Thunderbolt then TPS65982 is the part to use, TPS65981 does not support Thunderbolt.

Regards,

Peter

Hello.

I have a bit of a similar question to E2E team.

Is there difference between TPS65982AB, TPS65982DA, TPS65982DC ?

I see them in the market. Prices may vary.

Thanks.

Does this mean they are not interchangeable?

Hi Vitaliy,

They are not interchangeable for AB and Dx, DA-DC are PD2 and PD3 compliant devices.

Hello Peter.

Thank you for information.

I have not found that in datasheet on TPS65982.

Hi Vitaliy,

The datasheet is for AB and it's an early PD device which is PD 2.0 compliant. The newer products will have specified PD3.0 compliant in the datasheet.

The other devices are custom so not available in ti.com.

USB-IF has stopped certifying PD2.0 product, so we don't recommend 82AB for new designs.

Regards.

Peter
