Abstract
A driving device is disclosed, which relates to a technology for reducing consumption of a leakage current unnecessary for a driver circuit. The driving device includes: a pre-driver configured to output a drive control signal upon receiving a power-supply voltage in response to an input signal, and change a voltage level of the drive control signal in response to a control signal so as to selectively provide the changed voltage level; an output driver configured to receive the power-supply voltage in response to the drive control signal, and output the received power-supply voltage to an output terminal; and a bulk-voltage controller configured to selectively control bulk-voltage levels of the pre-driver and the output driver in response to the control signal.
Claims21
A driving device comprising:
- a pre-driver configured to output a drive control signal upon receiving a power-supply voltage in response to an input signal, and change a voltage level of the drive control signal in response to a control signal so as to selectively provide the changed voltage level;
- an output driver configured to receive the power-supply voltage in response to the drive control signal, and output the received power-supply voltage to an output terminal;
- and
- a bulk-voltage controller configured to selectively control bulk-voltage levels of the pre-driver and the output driver in response to the control signal,
- wherein the bulk-voltage controller includes:
- a pull-up bulk controller configured to output a pull-up bulk voltage and change a voltage level of the pull-up bulk voltage in response to the control signal;
- and
- a pull-down bulk controller configured to output a pull-down bulk voltage and change a voltage level of the pull-down bulk voltage in response to the control signal.
