GD3162 gate driver ADC

[Akshat_VE02376]

Hi NXP,
In our project, We are using AMUXIN for reading DC bus voltage and TSENSE for power device phase temperature. But we are planning to use TSENSE for AMUXIN reading. Is it possible? Will the ADC counts varry from what was read through AMUXIN? Please clarify

Hello Akshat

The internal configuration and description says that the AMUXIN could be used as GPI with a primary purpose for the ADC, this connection has additional control to the total error variation and other features.

The TSENSE includes possible current driver for temp sense network

If you use the TSENSE for the AMUXIN it might not cause an electrical error but these changes might affect the correct measurement.

If you want more details about these connections please read our official page GD3160: GD3160 Advanced IGBT/SiC Gate Driver - Data Sheet, this document is a secure file, so I cannot share it for this way.

I hope this information has helped you, please let me know if you need help with anything else.

Have a great day and best of luck.
