A LOW COST HALF BRIDGE DRIVER INTEGRATED CIRCUIT__

摘要

The present invention introduces a low cost half bridge driver IC that overcomes the drawbacks of the prior art. In particular this invention introduces a half bridge driver IC, which is fabricated in the process technology with minimum or reduced number of masking steps to implement all the blocks and without the use of the low threshold voltage CMOS. The inventive half bridge driver IC uses a universal 12 Volt supply for all 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 inventive half bridge driver IC, can provide enough voltage swing to set or reset the latch when high threshold voltage DMOS are used in the pulse filter.
