A method for overvoltage protection of a motor driver IC

This paper describes a circuit technique that allows semiconductor power devices to be safely used in an IC whose worst-case voltage requirements exceed the breakdown voltages of the power devices. The supply voltage is sensed and the circuit is placed into a non-operational but safe mode of operation (Turtle Mode/spl trade/). Device data is shown for a hard disk drive servo IC implementing this technique.
