Tool/software:
Greeting Ti team:
I'm using LM339DR2G Comparator to doing our over current protection. On the negative Input, I put 2.77V as stable voltage. When there is current, our detection model will generate IF voltage scale of current, which will dedicate sending to Input Voltage port. But I find out LM339 Negative Input Voltage drop when IF putting out.
Then I realize that I should put resister on Pin 11, It did work but there are still some voltage dropping and I really don't know why (Add1K Left/ Add 20K Right)
Thank you in advance for your assistance.
Regards,
Ziming Li
