App note: Matching MOSFET drivers to MOSFETs

Posted on Sunday, November 11th, 2012 in app notes by DP

Here’s an app note from Microchip detailing how to match MOSFET drivers to MOSFETs. There are many variations of MOSFETs out there, and matching one to your driver and vice-versa is essential to getting the most out of your system.

This Application Note discusses the details of MOSFET driver power dissipation in relation to MOSFET gate charge and operating frequency. It also discusses how to match MOSFET driver current drive capability and MOSFET gate charge based on desired turn-on and turn-off times of the MOSFET.
