The working principle of IXK611S1 gate driver is based on a charge pump circuit to generate a floating gate voltage Vgs, which is used to drive IGBTs and MOSFETs.A charge pump is used to step up the input voltage by switching the charging current from one capacitor to the other, thus achieving a high gate voltage at lower input voltage.The charge pump circuit is combined with a driver stage which amplifies the gate voltage up to the necessary level for driving the MOSFET or IGBT.

The IXK611S1 features adjustable dead-time that allows an adjustable delay of the rising and falling gate voltages to ensure that both devices are not switched on simultaneously. This helps to reduce switching losses, enhances system efficiency and improves system reliability.The IXK611S1 also features adaptive shoot-through protection, which ensures that the gate voltage is always within the safe operating range, even under extreme conditions.It also includes an internal buffer which helps to reduce EMI and makes it suitable for high switching frequency applications.

The IXK611S1 gate driver module from IXYS Integrated Circuits is an excellent solution for driving IGBTs and MOSFETs in high switching frequency applications such as control systems, motor drives, bridge-type DC-AC inverters, power supply systems, and automotive, medical, communications and consumer electronics. It offers standard logic level drive, matched on-resistance, adjustable gate voltage, low-gate capacitance, adjustable dead-time, and adaptive shoot-through protection, making it an ideal solution for high performance, reliable and efficient performance.
