Introduction

A gate driver is a system that controls the gate of a power device directly. It interfaces a low-power control circuit to a high-power circuit and helps with the smooth transition of power to the device, as well as providing protection in case of a fault. IXDE504D2 is a high performance gate driver of IXYS Corporation. It offers surge capability up to 15A per device, wide operating temperature range of -40 to + 105°C, and high voltage range (900V) rating.

IXDE504D2 Application Field

IXDE504D2 is widely used in industrial wiring box power, UPS (Uninterruptable Power Supply) systems, energy storage and other fields of power electronics. It provides shutdown protection in condition of high temperature, and adjustable UVLO (Under Voltage Lockout) function . The pulsed inputs of this chip are ideal for industrial level control, providing wide dynamic range of control with fast and solid switching.Primarily, IXDE504D2 is used in various switched mode power supplies (SMPS) and DC-DC converters. It helps in providing clean and glitch-free power with perfect transient behaviour, eliminating the need for traditional linear regulators.IXDE504D2 is also ideal for photovoltaic and solar energy converters, where it helps in controlling the output voltage, current and frequency of the circuit. Moreover, it\'s suitable for low power applications, like light dimmers and motor speed controllers.

IXDE504D2 Operating Principle

The IXDE504D2 has a simple yet versatile internal architecture. It consists of two independent drivers for controlling the gate drive of the power device, such as power MOS, FETS, IGBT, BJT and triacs.The active components included in the circuit are an NDMOS half bridge and two RDSon-regulated charge pumps. The NDMOS half bridge is responsible for the upper half of the driver\'s output while the RDSon-regulated charge pump generates the current necessary to drive the gate of the power device.The IXDE504D2 operates by using input signals like gate-source voltage, source-drain voltage, gate current and device capacitance, to control the output voltage and current. It ensures the adjustment of the dedicated power transistors without excessive switching losses.In addition, the IXDE504D2 also provides an over-temperature shutdown feature. This feature protects against overheating of the circuit, and helps in avoiding potential damage to the switching device.

Conclusion

In conclusion, IXDE504D2 is a high performance gate driver from IXYS Corporation that can be used in a wide range of power applications. It provides surge capability up to 15A per device, wide operating temperature range of -40 to + 105°C, and adjustable UVLO function. It can be used in various switched mode power supplies (SMPS) and DC-DC converters, as well as photovoltaic and solar energy converters. It also offers an over-temperature shutdown feature for protection against overheating.
