Claim 0:
1. A circuit comprising:
a controller having a driver control output
an electrostatic discharge (ESD) circuit having an ESD input, a driver control input, a first ESD output, a second ESD output, and a driver power input, wherein the driver control input is coupled to the driver control output;
a driver circuit having a first driver input, a second driver input, a driver output, a first voltage terminal, a second voltage terminal, a pull-up circuit coupled between the first voltage terminal and the driver output, a pull-down circuit coupled between the driver output and the second voltage terminal, wherein the first driver input is coupled to the first ESD output, the second driver input is coupled to the second ESD output, a pull-up control terminal of the pull-up circuit is coupled to the first driver input, and a pull-down control terminal of the pull-down circuit is coupled to the second driver input;
the ESD circuit is configured to provide a pull-down control signal at the second ESD output responsive to a state of the driver power input; and
the pull-down circuit is configured to disconnect the driver output from the second voltage terminal responsive to the pull-down control signal.
