Introduction

The ISL6620AIRZ-T is a high-performance, low-power gate driver targeted at Goggle networks, industrial or automotive application fields. It consists of two high-side and low-side P-Channel MOSFET drivers, designed to operate from an input voltage range of 4.5V to 24V, with a low on-resistance (RDS(on)) of 0.30Ohm. The device is capable of sourcing and sinking up to 4.5A with typical rise and fall times of 1.2µs.

Working Principle

The ISL6620AIRZ-T gate driver utilizes a dual power stage design to provide a lower RDS(on) for driving high power applications. By constructing a low RDS(on) MOSFET power stage, the gate drivers are able to provide better transient performance with lower losses while still maintaining excellent thermal capabilities. Additionally, the gate drivers are able to efficiently drive the high capacitance of receivers with little to no ringing and higher output accuracy as compared to single power stage drivers.

The gate drivers also incorporate an integrated voltage regulator that enables the device to operate over a wide range of input voltages without any external regulation. This allows for additional design flexibility and is a key benefit to customers looking to use the gate drivers in a wide range of applications. Additionally, the gate drivers are capable of driving slew rate requirements of up to 100V/µs, providing for a faster response time and greater switching efficiency.

Heat Dissipation Considerations

Excessive heat can cause a variety of problems with voltage regulators and gate driver components. To minimize this, the ISL6620AIRZ-T is designed to dissipate the heat quickly and efficiently. This is done by using thermal pad technology to facilitate heat transfer away from the device to the board quickly. Additionally, the gate drivers are protected with a built-in undervoltage monitoring feature as well as over-temperature protection. This ensures that the components are constantly at their ideal temperature, even in the toughest operating environments.

Package Design

The ISL6620AIRZ-T is designed to fit the industry standard 5.5mmx6mm package. This allows for a wide range of applications with little concern for board space. It also makes it easier for customers to find suitable components to match the package size. The gate drivers also utilize a standard pin-out configuration to make the design process smooth and simple.

Conclusion

The ISL6620AIRZ-T is a high-performance, low-power gate driver targeted at Goggle networks, industrial or automotive application fields. It features a low RDS(on) of 0.30Ohm, allowing it to drive high power applications efficiently. Additionally, the built-in voltage regulator and over-temperature protection enable the device to operate in the toughest of environments. The gate drivers are also available in a standard 5.5mmx6mm package, making them easy to use in a variety of designs.
