  • Patent number: 10979032
    Abstract: Circuits and devices are provided for reliably maintaining a normally-off Gate Injection Transistor (GIT), or similar, in a non-conducting state when a gate of the GIT is not driven with a turn-on control signal. This is accomplished using a failsafe pulldown coupled to the GIT's gate. The failsafe pulldown includes a resistance modulation circuit, which varies the effective gate resistance of the GIT, such that a low resistance is provided for an interval immediately after a turn-on transition of the GIT, thereby facilitating a high-current pulse for charging the GIT's gate. Subsequently, a high resistance is provided, such that a much lower current is driven to maintain the GIT in its on state. The failsafe pulldown enables a GIT, or similar, to be driven with a relatively simple driver, which may be provided external to the power switch device or integrated in the same die as the power switch.

  • Patent number: 10958269
    Abstract: A bridge output circuit of the present invention reduces the dead time. Upon receiving an input signal (SIN) for indicating on state of a high-side transistor (1H), a gate control signal generation circuit (4) outputs a low-side gate control signal (LGCTL) for turning off a low-side transistor (1L) to a low-side driver circuit (2L). On the other hand, a high-side gate control signal (HGCTL) for turning on the high-side transistor is generated from a signal delayed the low-side gate control signal and outputted to a high-side driver circuit (2H). The time of delay is controlled by the input signal (SIN), a signal (LGFB) indicating on/off state of the low-side transistor, and a signal (SOUT_L) indicating a level of an output signal.
