  • High voltage switch pre-driver circuit
    Patent number: 8222929
    Abstract: Switch pre-driver systems and methods are described. The present switch pre-driver systems and methods facilitate switch driver breakdown protection, reduction of leakage current, and avoidance of false switching. In one embodiment, a switch system includes a switch driver, a switch pre-driver, and a mode detection circuit. The switch driver drives a voltage. The switch pre-driver controls the switch driver. The mode detection circuit notifies the switch pre-driver of a mode condition.
