Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A driver circuit, comprising:
at least one current source coupled between a supply voltage terminal and a first output node of the driver circuit, the at least one current source configured to supply a charge current during a pre-charge monopulse time period during and less than a driver disable time period when the driver circuit is disabled, the charge current being less than a current supplied by the at least one current source when the driver circuit is enabled;
another current source coupled to a ground terminal of the driver circuit, the another current source configured to be disabled during the driver disable time period;
a charge current source coupled between the supply voltage terminal and a second output node of the driver circuit, the charge current source configured to be enabled during the pre-charge monopulse time period;
a first current switch coupled to the first output node, the first current switch having a control terminal and configured to be charged during the pre-charge monopulse time period;
a second current switch coupled to the second output node, the second current switch having a control terminal and configured to be charged during the pre-charge monopulse time period;
a first pull-down switch coupled between the control terminal of the first current switch and ground, the first pull-down switch configured to be activated during the pre-charge monopulse time period; and
a second pull-down switch coupled between the control terminal of the second current switch and ground, the second pull-down switch configured to be activated during the pre-charge monopulse time period.
