Abstract
Abstract A single chip integrated circuit includes a boost regulated DC-to-DC converter and gate drive circuits integrated on the same die with a micro-processor, along with high density digital logic functions, analog functions, etc. The gate drive circuits are used to drive external power FETs, particularly high side NMOS. The micro-processor may also be some type of micro-controller or digital signal processor. By being able to place these functions on a single integrated circuit, a motor or actuator control system can be placed on a single chip. With appropriate sensors to provide feedback to the integrated circuit, a system which is capable of executing actuator move functions, such as position, velocity, velocity profile, torque, etc., and sequencing these events as well is included.
