Part Number: TIDA-00528
Other Parts Discussed in Thread: INA290, INA293, LM5056A

Dear team,

My customer are looking for 100V voltage monitoring solution for their application,

I found TIDA-00528 which is close to their spec.

Did we have 100V voltage monitoring reference design can share with customer?

thanks!

Hi Ben,

The reference design you mentioned should work for 100V. What other features are required but are missing from this design? If you could elaborate on the specifics, maybe we can look into whether it can be tweaked to fit the requirements.

If analog output current sense amplifier is an option, you may want to look into INA290 and INA293. These devices can work with common mode input of up to 110V. the circuit would be much simpler.

Hi Guang,

thanks for your comments. we move our solution to LM5056A since Vbus voltage is down to 60V.
