Vishay Siliconix AN804 P-Channel MOSFET Application Note

About this manual

The document explains that while n-channel MOSFETs are often preferred due to lower resistivity, p-channel devices are essential for specific high-side switching tasks. It details how a p-channel MOSFET can be used with an n-channel device to simulate a high-current, high-power CMOS arrangement.

What's inside

• High-Side Switching
• Switching Ground-Return Loads
• Totem-Pole Arrangement
• Gate Drive Techniques
• Crossover Current Reduction

Frequently asked questions
