Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An application requires a gate drive circuit with a capacitance of 1nF and needs to switch at a rate of 100 kHz. Calculate the necessary gate drive current. Then, discuss potential effects of slower switching times.

💡 Hint: Think about how fast or slow voltage transitions impact temperature.

Challenge 2 Hard

Design a bootstrap circuit to work with a 12V high-side NMOS. Describe the component roles and how you'd ensure VGS remains above Vth.

💡 Hint: Consider what happens during switching and the required voltage levels.
