Abstract
A low cost half bridge driver IC fabricated in the process technology with a minimum or reduced number of masking steps to implement all the blocks and without the use of the low threshold voltage CMOS. The half bridge driver IC uses a universal 12 Volt supply for all of the blocks with reference to the ground or to the half bridge output. Furthermore, the low differential current from high voltage level shifter transistors of the half bridge driver IC can provide enough voltage swing to set or reset the latch when high threshold voltage DMOS transistors are used in the pulse filter.
