Expanding the voltage range of the HIP1020 FET driver

Posted: 18 Sep 2009 ?? ?Print Version ?Bookmark and Share

Keywords:HIP1020 driver FET? voltage range? expand voltage range?

The HIP1020 is a flexible FET driver designed to support up to 12V and down to 3.3V supplies. Yet, using a simple network, you can expand the FET driver's voltage range. This application note offers a solution for controlling 24V, 5V and -5V supplies. We used the HIP1020, but the concepts can be applied to many FET controllers of this type.

The solution is divided into three FET designs, first starting with the simple +5V controller, then addressing the +24V controller and finishing up with the -5V controller. This application note addresses most of the common MOSFET types and discusses why each MOSFET was selected for the particular supply voltage.
