ABSTRACT:
An integrated driver with improved load current sense capability includes a first transistor, a first amplifier, a second transistor, a third transistor, a second amplifier and a fourth transistor. The integrated driver allows for significantly better fault handling capability, provides accurate thermal and current sensing capability and reduces I/O pin count over prior designs.
