Thank you for your attention!
As the pdf shows, our company manufactures Hall effect current sensors and has been using your RC4580 chips. At the end of 2025, we found that chips from **Lot TI57** were prone to damage, with a failure rate of approximately 20%. Moreover, chips that passed initial screening and testing showed damage again after being stored for 14 days. The failure symptoms include: - **Smoking of the chip** - **Zero output loss** in our current sensors We kindly ask for your support in analyzing the root cause. Thank you very much. We look forward to your reply.
