The DEIC421 is a CMOS high speed high current gate driver specifically designed to drive MOSFETs in Class D, E, and RF applications at up to 45MHz, as well as other applications requiring ultrafast rise and fall times or short minimum pulse widths.
The DEIC421 is an improved version of the DEIC420. The DEIC421 incorporates a Kelvin ground connection on the input side to remove potential ground bounce induced by the large currents present in the output stage ground path. If needed, the Kelvin connection also allows use of a common mode choke as an additional measure in preventing false triggering. The internal layout of the package has been improved to reduce inductance. The DEIC421 can source and sink 20A 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 compatible with +5V or CMOS and is fully immune to latch up over the entire operating range. Its features and wide safety margin in operating voltage and power make the DEIC421 unmatched in performance and value. The DEIC421 is packaged in DEI’s new 7 leaded low inductance RF package. The DEIC421 is a surface-mount device, and incorporates patented RF layout techniques to minimize stray lead inductances for optimum switching performance.
