GATE DRIVER CIRCUIT and CHIP

A chip, comprising:

• a gate driver circuit, wherein the gate driver circuit comprises:
• a first current output circuit, a channel selection circuit, and an output stage circuit;
• wherein
• an output terminal of the first current output circuit is electrically connected to a first terminal of the channel selection circuit, a second terminal of the channel selection circuit is configured to receive a control signal, the control signal being used for controlling the gate driver circuit to drive a switch transistor to be turned on or turned off, a third terminal of the channel selection circuit is electrically connected to a first input terminal of the output stage circuit, a fourth terminal of the channel selection circuit is electrically connected to a second input terminal of the output stage circuit, and an output terminal of the output stage circuit is electrically connected to a gate electrode of the switch transistor, wherein one control circuit is arranged in the channel selection circuit;
• the first current output circuit is configured to transmit a first current to the channel selection circuit, the first current serving as a reference current;
• the channel selection circuit is configured to select a transmission channel for the first current based on the control signal, and transmit the first current to the output stage circuit over the transmission channel;
• and
• the output stage circuit is configured to output a second current based on the first current to drive the switch transistor to be turned on or turned off, the second current being used for pulling up or pulling down a gate voltage of the switch transistor.
