  • Power system inhibit method and device and structure therefor
    Patent number: 7826238
    Abstract: A power control system (25) uses two separate currents to control a startup operation of the power control system (25). The two currents are shunted to ground to inhibit operation of the power control system (25) and one of the two currents is disabled to minimize power dissipation. The two independently controlled currents are generated by a multiple output current high voltage device (12) responsively to two separate control signals (23,24).
