Abstract:
A gate control circuit for controlling gates of at least a half side of an H-bridge circuit includes: an input terminal configured to connect to a PWM signal; a power terminal configured to connect to a voltage source that supplies a positive voltage; a ground terminal configured to connect to a ground reference; and a control circuit connected with the input terminal, the power terminal, and the ground terminal. The control circuit includes: two high side switches configured to be connected with the voltage source respectively through the power terminal; two low side switches configured to be connected with the ground reference respectively through the ground terminal; a first inverter connecting the two high side switches; a second inverter connecting the two low side switches; and a first resistor and a second resistor connecting the two high side switches to the two low side switches respectively.
