In 1989, International Rectifier (IR) introduced the first monolithic HVIC gate driver product, the high-voltage integrated circuit (HVIC) technology uses patented and proprietary monolithic structures integrating bipolar, CMOS, and lateral DMOS devices with breakdown voltages above 700 V and 1400 V for operating offset voltages of 600 V and 1200 V. An integrated gate-driver solution reduces design complexity, development time, bill of materials (BOM), and board space while improving reliability over discretely-implemented gate-drive solutions. A gate driver IC serves as the interface between control signals (digital or analog controllers) and power switches (IGBTs, MOSFETs, SiC MOSFETs, and GaN HEMTs). In essence, a gate driver consists of a level shifter in combination with an amplifier. Gate drivers can be provided either on-chip or as a discrete module. JSTOR ( October 2015) ( Learn how and when to remove this template message)Ī gate driver is a power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as an IGBT or power MOSFET.Unsourced material may be challenged and removed.
