Modern electronic systems are complex and have various components such as Field Programmable Gate Arrays (FPGAs), Batteries and Motors -all of which require their own power supply systems and demand specific voltages.To generate these voltages, designers use either a Pulse Width Modulation (PWM) or Linear Solution, both of which have their own set of advantages and disadvantages. The PWM solutions are generally more efficient and suitable for low load applications; however, they can introduce alternate harmonic distortions of the supply frequency, referred to as switching noise, which can interfere with other components in the system.

In order to eliminate switching noise and ensure a robust and stable power supply system, designers use a gate driver.An efficient gate driver helps avoid the high voltage losses often seen in linear solutions by enabling low voltage, high current pulses that switch devices at a high speed.This article will focus on the IR2235JPBF gate driver from International Rectifier and its application field and working principles.

IR2235JPBF Gate Driver

The IR2235JPBF is a high performance, bipolar, dual MOSFET gate driver.It has an integrated boost circuit that allows it to withstand high-voltage transients and supply voltage ranges of 6V to 20V.The maximum peak output current is 1.5A and the minimum peak-to-peak output voltage is 4.5V.This allows the gate driver to deliver consistent switching speed and accurate logic thresholds, even at extreme temperatures.

The driver also features a built-in low voltage sensing circuit which monitors the supply voltage and automatically adjusts the threshold for the input logic.This ensures that the gate driver will remain functional even when the supply voltage drops below the threshold value.In addition, the IR2235JPBF gate driver has an integrated over current protection feature, which limits the output current when the supply voltage exceeds the absolute maximum rating.

Application Field of IR2235JPBF Gate Driver

Due to its robust design and high performance, the IR2235JPBF is suitable for a wide range of industrial and automotive applications.It is particularly suited for motor control, lighting control, power distribution, switch mode current control and embedded systems.It is also well-suited for driving high side MOSFETs and IGBTs in a variety of power supply and motor control circuits, such as three-phase inverters, AC-DC converters and switched-mode power supplies.

Working Principles of IR2235JPBF Gate Driver

The IR2235JPBF gate driver integrates a high-speed low-saturation dual-channel MOSFET driver and two logic level detector circuits.The driver enables low voltage and high current signals to be fed into a MOSFET gate, while the logic level detectors sense the logic levels of the signals and adjust the thresholds accordingly.The integrated high-side and low-side drivers are self-coregulated and are capable of switching at high speed with minimal dead-time.

The gate driver supports a wide range of MOSFET types and is configurable for either single-ended or split-supply operation.The built-in adjustable dead-time control ensures optimized operation of the MOSFETs, while the internal voltage sensing circuit provides protection against over-current, short circuits and other faults.In addition, the integrated thermal shutdown circuit helps prevent damage to the gate driver from excessive temperatures.

Conclusion

The IR2235JPBF is an efficient, high-performance gate driver which is well-suited for a variety of industrial and automotive applications.It features an integrated boost circuit to withstand high voltage transients, a low voltage sensing circuit to monitor supply voltage, and an over-current protection feature.The driver integrates a high-speed low-saturation dual-channel MOSFET driver and two logic level detectors, enabling it to switch at high speeds with minimal dead-time.Finally, it has an integrated thermal shutdown circuit, which helps prevent damage to the driver from excessive temperatures.
