Integrated gate drivers have become a popular choice among engineers when using power control integrated circuits (PMICs) to control power in electronic systems that require a fast, robust and reliable signal to switch the power device between an on and off state. The IX2R11S3 is one such integrated gate driver device that provides a cost-effective solution to power control issues and allows the user to control the power on/off switching with minimal effort.

The IX2R11S3 is a two-channel, high-speed, high-current and low-power, low-profile MOSFET/IGBT gate driver. This gate driver can be used for driving N-Channel power MOSFETs and IGBTs with a maximum peak current of ~3.6A, and a typical turn-on rise time of ~12ns. It also offers brief current protection circuitry, along with short circuit and over voltage protections.

This integrated gate driver device is designed to be used in a wide range of application fields, such as in medium voltage motor drives and solar inverters, Uninterruptible Power Supplies (UPS), power supplies and battery management systems, automotive powertrain, and industrial control systems. It also finds application in low and medium voltage AC-DC and DC-DC converters.

The IX2R11S3 offers several features that enable it to provide quick and reliable operation in power control applications. It has two independent integrated high-side low-side driver stages, each capable of driving a 600V power device. These stages, combined with a low-noise charge pump, all reduce the external components required and help in achieving high efficiency and cost savings. The IX2R11S3 also offers fault lockout protection to keep the system safe. Moreover, it offers programmable dead-time and adjustable current threshold.

The working principle of the IX2R11S3 is; each of the two channels contain a low-side driver and a high-side driver. The low-side driver is used to turn on the power device by providing an appropriate voltage to the gate of the power device. Similarly, the high-side driver is used to turn off the power device by providing an appropriate voltage to the gate of the power device. This switching action is regulated and framed by the low-noise charge pump and fault lockout protection circuit. The adjustable current threshold and programmable dead-time are used to control the switching action of the gate driver.

In conclusion, the IX2R11S3 gate driver offers an innovative, cost-effective, and reliable solution for power control applications. It has a small form factor, convenient PIN configuration, and sophisticated fault protection which makes it ideal for high power applications. The adjustable current threshold and programmable dead-time are beneficial features that improve the device’s performance in critical applications. Therefore, the IX2R11S3 gate driver is an ideal choice for power control applications in various fields such as automotive, industrial, and solar energy.
