THS6222: 125degree ambient

Hello Brian,

Could you elaborate on what aspects of the THS6222 you would need in a higher temp amp?

For example:

Package Size

Differential Signal Line Driving (both amps used together differentially)

High Power supplies

Current drive target

Distortion target

Please share if any of these, or other specs, are of interest to the solar inverter application.  In the meanwhile I will review our portfolio for options to share.

Best,

Alec

Thanks Alec.

In the solar system of 350KW power rating, the ambient temp in the system box would be expected up to 75degree. Customer is adapting TIDA design as below. In which, the THVD8000 + THS6222 are plan to implment. 

Application: PLC in 350KW PV Inverter system. 

Supply voltage: 12V for THS6222.

Driving capability: The power cable distance between PLC TX and PLC RX is about 400M., it would need higher driving capability. 

Diff. LINE: PLC signal is coming from THVD8000

There are two questions here.

1. Is there device with better thermal capability? Do you think THS6222 is able to design on this system? 

2. How to estimate the power consumption of the THS6222? and how to estimate its junction temp?

TIDA-010935

Hello Brian,

Thank you for the expanded details.  I will check with our experts on process technologies and design to see if we have any internal guidance on the thermal ceiling for operating the THS6222 as described.  As for the estimation of power draw and junction temp, allow me a bit of time to provide a method of doing so.

Best,

Alec
