2024-01-10, Integrating ideal diodes, source selectors, and eFuse helps enhance system robustness

This paper studies ideal diodes with back-to-back MOSFETs as well as other more advanced devices. An ideal diode solution that integrates multiple functions to provide overall system protection is also presented. Diodes are very useful devices and are important for many applications. Standard silicon diodes have a voltage drop of 0.6V to 0.7V. The Schottky diode has a voltage drop of 0.3V. In general, the voltage drop is not a problem, but in high current applications, the individual voltage drops can produce significant power losses. Ideal diodes are ideal devices for such applications.
