ABSTRACT:
A system-on-a-chip (SOC) in CMOS technology capable to support high voltage applications has been achieved. The single chip system of the present invention comprises high-voltage circuitry, a complete micro-controller system including all timing control, interrupt logic, flash EEPROM program memory, RAM, flash EEPROM data memory and I/O necessary to implement dedicated control functions, and a core and system peripheral bus. A preferred embodiment of the invention is shown driving a DC-motor in a H-bridge configuration, having an AMR-position detection and control. A pulse width modulation (PWM) is applied to high-voltage (30 to 60 Volts or in lower ranges less than 30 Volts) CMOS buffers for steering CMOS-FETs or relays of the motor H-bridge.
