Introduction to IR21814SPBF Application Field and Working Principle
The IR21814SPBF is a Gate Driver, which belongs to the Power Management Integrated Circuit (PMIC) group, and is typically used in applications such as motor control systems, switch mode power supplies, UPS, air conditioning, and other power conversion systems. The IR21814SPBF is an integrated circuit that enables superior gate current control with the intention of driving IGBTs (Insulated Gate Bipolar Transistors) and MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors).Functionality of IR21814SPBF
The IR21814SPBF is an integrated circuit that provides superior gate current control, protection and gate drive circuit capability. It supports a wide operating temperature range from -40°C to +125°C. It has a wide operating voltage range of up to 38V, which supports the standard gate voltage level including the boost voltage level and the floating voltage level. It also supports a wide output current and power level up to 3.2A, which is beneficial for powering IGBTs and MOSFETs in motor control systems, automotive and other power electronics applications. The IR21814SPBF includes integrated features such as an auto-restart mode, a fault-interrupt signal, an input signal conditioner, and adjustable electrical parameters such as gate hysterisis and threshold voltage level to help optimize motor control systems and power conversion systems. Moreover, it also incorporates a wide range of protection features such as over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, and reverse current protection.IR21814SPBF Working Principle
The working principle of the IR21814SPBF is quite simple and straightforward. When the logic signal from its input is at low level, the current output from the Gate Driver will be disabled, inhibiting the switching device from conducting current. On the other hand, when the logic signal from its input is at high level, the current output from the Gate Driver will be enabled, allowing the switching device to conduct current. A wide output current and power level up to 3.2A is supported. The current output from the Gate Driver is protected against multiple events such as over-voltage, under-voltage, over-current, over-temperature, and reverse current. In case of any of these events being detected, the Gate Driver will automatically signal a fault signal and interrupt the logic signal from its output. Furthermore, the IR21814SPBF also has adjustable electrical parameters such as gate hysterisis and threshold voltage level to help optimize motor control systems and power conversion systems.Conclusion
In conclusion, the IR21814SPBF is an integrated circuit that belongs to the PMIC - Gate Drivers group and is used to drive IGBTs and MOSFETs in motor control systems, switch mode power supplies, and other power conversion systems. It offers superior gate current control, protection and gate drive circuit capability and a wide operating temperature range from -40°C to +125°C. Moreover, it also incorporates a wide range of protection features such as over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, and reverse current protection. It has adjustable electrical parameters such as gate hysterisis and threshold voltage level to optimize motor control systems and power conversion systems.The specific data is subject to PDF, and the above content is for reference
