发明名称 GATE DRIVER
摘要 A gate driver is provided. The gate driver amplifies an input control signal to drive gates of high and low side transistors. A high side driving chip amplifies a high side control signal for controlling the high side transistor and outputs the amplified high side control signal to the gate of the high side transistor. A low side driving chip amplifies a low side control signal and outputs the amplified low side control signal to the gate of the low side transistor. An emitter terminal of the gate of the high side transistor is connected to a collector terminal of the low side transistor. The high side driving chip is separately prepared from the low side driving chip.

主权项 1. A gate driver amplifying an input control signal to drive gates of high and low side transistors, comprising: a high side driving chip amplifying a high side control signal for controlling the high side transistor and outputting the amplified high side control signal to the gate of the high side transistor; and a low side driving chip amplifying a low side control signal and outputting the amplified low side control signal to the gate of the low side transistor, wherein an emitter terminal of the gate of the high side transistor is connected to a collector terminal of the low side transistor, the high side driving chip is separately prepared from the low side driving chip, and the low side driving chip comprises a dead time control unit dead-time controlling the low side control signal and generating the dead-time controlled low side control signal, and an output driver amplifying the dead-time controlled low side control signal and outputting the amplified signal.
