  • Bootstrap gate driver
    Patent number: 8710875
    Abstract: A bootstrap gate driver including a load indication unit, a bootstrap gate-drive unit and a drive-control unit is provided. The load indication unit is configured to generate a load indication signal in response to a state of a load. The bootstrap gate-drive unit is configured to drive a switch-transistor circuit in response to an inputted pulse-width-modulation (PWM) signal, wherein the switch-transistor circuit has a high-side driving path and a low-side driving path. The drive-control unit is coupled to the load indication unit and the bootstrap gate-drive unit, and configured to enable or disable the high-side driving path in response to the load indication signal. In the invention, the operation of the low-side driving path is not affected by enabling or disabling the high-side driving path.
