Abstract

This work analyzes the impact of working conditions on the current collapse (CC) phenomenon for an automotive GaN device. For this purpose, some sensing circuits have been compared to find the most suitable for the considered GaN family. Simulations of the testing schematic have been performed, a prototype board has been created, and some measurements have been taken. Finally, the work has investigated the effect on the CC of the input voltage, current level, switching frequency, and duty cycle. The key outcome is that the temperature increment mitigates the CC phenomenon, which implies that the on-state resistance worsening (dynamic/static ratio), which is due to the CC, reduces with increasing temperature. Therefore, the typical increment of the dynamic on-resistance (RDSON) with increasing temperature is ascribable to the increment of the static one with temperature, while it is not at all an exacerbation of the current collapse phenomenon.

18. Monolithic Schottky diode in ST F7 LV MOSFET technology: Performance improvement in application.

Author

Subjects
*METAL oxide semiconductor field-effect transistors, *SCHOTTKY barrier diodes, *SWITCHING power supplies, *DIODES, *ELECTRICITY, *BRIDGES (Computer networks), *MANAGEMENT
Abstract

The article focuses on metal-oxide-semiconductor field-effect transistor (MOSFET) technology and compares it with monolithic Schottky diode as evaluated in switching-mode power supply (SMPS) and motor control environments. Topics include role of dynamic behavior of intrinsic body-drain diode in MOSFET performance; benefits of Mono Schottky in a power management environment; and switching behavior improvement in bridge topologies.
