MSP430FR50431: USS drive of external FETs or bridge driver

Boone

Part Number: MSP430FR50431

Hello,

I'd like to know if the USS is capable of driving external FETs or H/F bridges in order to achieve a higher drive voltage (20-30V) on the transducers? If yes, can you point me to any documentation or projects that have implemented this? Any guidance is much appreciated!

Thank you!

Hi,

This appnote may help you. https://www.ti.com/tool/TIDA-01486

However, please be noticed that applying extra components could cause a worse performance on the USS module. Especially, the ZFD performance.

Best regards,

Hello,

what does ZFD performance mean?

Thank you.

Hi,

The ZFD means the zero-flow drift of the dTOF over temperature. You can find more related information about the ZFD through this app note. https://www.ti.com/lit/ug/tiduej6a/tiduej6a.pdf
