PMIC - Gate Drivers have become an integral part of modern electronics. They provide an interface between the high driving currents required to efficiently operate power transistors and the low voltages and levels delivered by logic systems. IXJ611S1T/R application field and working principle is an example of such a PMIC. It is an integrated power driver and an integrated impedance matching circuit specifically designed for high current applications such as driving MOSFETs, insulated gate bipolar transistors (IGBT), and triacs. It has a typical operating voltage range of 3V to 18V and is designed to operate at a maximum input frequency of 8MHz.

Ground Breaking Design

The IXJ611S1T/R is designed with a ground breaking three-mode control configuration which not only allows for fast switching of MOSFETs, IGBTs and triacs, but also provides the user with added measures of protection from hardware faults. The three-mode control configuration works as follows: first, the logic is enabled when the Enable pin is high; second, the GATE pin is driven high when the logic is enabled; and third, the logic is disabled when the Enable pin is low. The IXJ611S1T/R integrates a level-shifting circuit, which allows the user to control the output voltage using the Enable pin. Furthermore, the IXJ611S1T/R features a built-in protection circuit that monitors the drain-to-source peak current. As such, it will automatically shut off the gate driver when the peak current of the MOSFET exceed the pre-set limits.

Applications

The IXJ611S1T/R is widely used to provide power in large scale DC-DC converters, motor controllers and other applications where the performance and reliability of the system depends on fast switching of power devices. It is also ideal for applications that require high-current, high-voltage, and high-power performance. Its built-in advanced protections such as reverse-current protection and over-current protection make it a great choice for applications such as phase-shifted full-bridge converters, half-bridge converters, and active-clamp zero-voltage switching converters. Additionally, its advanced control system allows for fast, efficient and reliable switch control over a range of power devices.

Working Principles

The IXJ611S1T/R works on both the positive and negative power polarity and is designed to provide efficient drive switching for devices such as MOSFETs and IGBTs. The positive power polarity works as follows: when the logic signal is enabled, the gate of the device is driven to its high voltage level and when the logic signal is disabled, the gate of the device is driven to its low-voltage level. This ensures that the device’s switching times are optimized while protecting it from over-current faults. The negative power polarity utilizes the same basic principle, but instead of driving the gate of the device to a high-voltage level, it drives it to a low-voltage level when the logic signal is enabled.

The IXJ611S1T/R is an advanced power driver, which features superior performance and reliability. Its integrated level-shifting circuit, peak current monitoring circuit, and three-mode control configuration make it an ideal choice for applications that require fast switch control and protection.
