Abstract

A gate driver circuit applicable to an inductive load, an inverter module, and an inverter apparatus are provided. The gate driver circuit includes a high side driver having a first output side and a first control side and generating a high side gate signal; and a low side driver generating a low side gate signal, wherein the high side driver includes a first VS pad formed on the first output side; a first output pad formed on the first output side, a first VB pad formed on the first control side; and a second VS pad formed to be adjacent to the first VB pad on the first control side and electrically connected to the first VS pad; and a first circuit unit connected to the plurality of pads to provide the high side gate signal through the first output pad.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0071844 filed with the Korean Intellectual Property Office on July 2, 2012, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a gate driver circuit, an inverter module, and an inverter device applied to an inductive load such as a motor. Background technique [0004] In general, in order to supply a drive signal to an inductive load used in electronic products such as electric vehicles, an inverter (inverter) that converts DC voltage to AC voltage is used, and in order to drive the inverter, it is necessary to generate a gate signal to the gate driver. Here, the inductive load may include a motor, a heating coil, and the like. [0005] In general, an inverter includes a high-side switch and a low-side switch to generate an AC voltage. The high-side switch and the low-side s...
