5 Conclusion

The surge in AI processing power has driven a critical shift toward 800VDC power delivery in AI server racks to accommodate the increasing power requirements of advanced AI processors and support high compute density. This shift creates new challenges for system protection and monitoring, particularly during hot-swap events.

TI is at the forefront of development with the LMI800PS high-voltage hot-swap controller, which effectively manages inrush currents, offers comprehensive telemetry for system diagnostics and safety, and maintains reliable operation.
