The LMG1205YFXT is an integrated Gate Driver designed to drive low-voltage Power MOSFETs and IGBTs. It is specifically designed for high-performance applications such as motor drives, solar inverters, switching power supplies and AC or DC motor controls. This driver has been developed with our world-class proprietary process technology, which preserves signal-to-noise and output-current margins over temperature and time, making it robust and suitable for use in harsh environments.

LMG1205YFXT comes with a wide input voltage range of 4.5V-20V and can switch up to 5A output current, making it suitable for a huge range of applications. It also supports internal self-protection against overcurrent, over temperature and under voltage lock-out (UVLO).

The device has an integrated High Side Fly-Back Diode and an internal clamping circuit which helps reduce complex external components. The LMG1205YFXT also has two external gate resistors which help reduce noise and ringing which can cause gate emissions.

As the gate driver is designed for low-voltage applications, the high-side MOSFET must be protected from various overvoltage damages. To this end, the internal clamping circuit has been designed to ensure that the voltage on the high-side MOSFET is limited to the absolute maximum rating. This helps to ensure the life-time of the MOSFET.

The LMG1205YFXT is also specially designed to reduce EMI radiation, with diode-clamped output pins which reduce signal ringing and noise. It is also equipped with an internal charge pump which provides sufficient voltage to drive the MOSFET. This minimizes the gate capacitance and provides more stable current drive.

The LMG1205YFXT can be controlled by a Logic Input pin, which means that it can be used in both synchronous and asynchronous switching applications. For applications which require high rise and fall times, the integrated phase-shift-controlled PWM circuit offers highly accurate and smooth transitions.

Overall, the LMG1205YFXT is an excellent solution for motor drive systems, solar inverters and AC or DC motor controls. It is designed for high-performance applications and offers an internal self-protection against overcurrent, over temperature and under voltage lock-out.

This gate driver also comes with a wide input voltage range, a high output current and a variety of features designed to reduce EMI radiation and ensure a long life-time for the MOSFETs. It is a reliable and robust solution for any number of applications.
