Description
The DEIC515 is a CMOS high speed high current gate
driver specifically designed to drive MOSFETs in Class
D, E, and HF, RF applications at up to 45MHz, as well as
other applications requiring ultrafast rise and fall times or
short minimum pulse widths. The DEIC515 can source
and sink 15A of peak current while producing voltage
rise and fall times of less than 4ns, and minimum pulse
widths of 8ns. The input of the driver is fully immune to
latch up over the entire operating range. Its features and
wide safety margin in operating voltage and power make
the DEIC515 unmatched in performance and value.
The DEIC515 is packaged in DEI's low inductance RF
package incorporating DEI's patented (1) RF layout
techniques to minimize stray lead inductances for
optimum switching performance. The DEIC515 is a
surface-mount device. (1) DEI U.S. Patent #4,891,686
