The EL7222CS-T13 power management integrated circuit provides reliable driving scheme for controlling N-channel power MOSFETs and N-channel IGBTs. This gate driver features wide supply voltage range from 10V to 60V with a maximum output current of 3A, which provides smooth and fast switching speed. The IC also integrated a variety of protective functions such as overcurrent protection, undervoltage lockout, overvoltage protection and shoot-through prevention, which makes it suitable for high-efficiency applications without compromising performance or reliability.

The EL7222CS-T13 is a highly integrated PMIC gate driver which can be used as a single-piece solution in various power electronics applications. It is suitable for a wide range of applications, including motor drives, PV inverters, switching regulators, DC-DC converters and power supplies. It can be used to drive large motors and small motors, DC motors and AC motors, and is also suitable for high frequency switching power systems. In addition, it can be used to drive low power transistors and IGBTs, making it ideal for power control applications.

The working principle of the EL7222CS-T13 is based on the principle of pulse width modulation (PWM). When a signal level changes, a short pulse width is send through the gate of the MOSFET or IGBT. This short pulse will activate the switch and charge the gate to the signal level, then the switch is turned on, applying physical power to the switch. The length of the pulse width is adjustable and can be set to achieve fast switching for high-efficiency operations.

The EL7222CS-T13 also includes a slew-rate control function. This function enables the gate driver to adjust the transition speed of gate drive output, preventing electromagnetic interference in the operating environment and prolonging the lifetime of the MOSFET or IGBT. The slew-rate control function is also helpful in achieving fast, efficient operations.

In summary, the EL7222CS-T13 is a high integration, reliable and efficent PMIC gate drive product by Elionix that offers excellent performance in various power electronics system. It is suitable for a wide range of applications, including power supplies, motor drives, PV inverters, switching regulator and dc-dc converters. Its wide supply voltage range, maximum output current capability and protection functions makes it ideal for high-efficiency operations. It works based on the principle of pulse width modulation, and also includes a slew-rate control function for better electromagnetic interference protection and efficient operations.
