Abstract
An output driver includes a switching device having a first node coupled to a gate of a power switch and pulling down a voltage level of the gate of the power switch to prevent a premature turn-on of the power switch. A pull-down circuit is coupled to the switching device and keeping the switching device from being turned on to prevent the premature turn-on of the power switch.
Claims20
An output driver, comprising:
- a switching device having a first node coupled to a gate of a power switch and pulling down a voltage level of the gate of the power switch to prevent a premature turn-on of the power switch;
- and
- a pull-down circuit coupled to the switching device and keeping the switching device from being turned on to prevent the premature turn-on of the power switch.
An apparatus, comprising:
- a controller;
- and
- an output driver including
- a switching device having a first node coupled to a gate of a power switch and pulling down a voltage level of the gate of the power switch to prevent a premature turn-on of the power switch, and
- a pull-down circuit coupled to the switching device and keeping the switching device from being turned on to prevent the premature turn-on of the power switch.

A method for controlling an output driver, the method comprising:
- pulling down a level of a voltage at a first node to prevent a premature turn-on of a power switch coupled to the output driver, the first node being coupled to a switching device and a gate of the power switch;
- turning off the switching device using a pull-down circuit;
- and
- outputting a driving signal to the power switch.
