Power Management Integrated Circuits (PMICs) play an increasingly important role in the development of modern electronics. Gates drivers are essential components within PMICs, providing the necessary control signals to turn transistors or other parts of the circuit “on” and “off”, in order to deliver the correct levels of current and/or voltage to different areas of the circuit. The LM5110-1SD/NOPB is a high-performance gate driver which can be used in a wide range of applications.

Designers rely on the LM5110-1SD/NOPB to accurately control the drive voltage and current to the power MOSFETs and IGBTs used in various environments. The device features energy efficient, low-voltage operation, low quiescent current, and a fast switching time of 60ns - enabling a wide range of applications while reducing power consumption and delivering accurate and reliable thermal management.

The robust LX, Shutdown Control (SD) and Enable (EN) inputs feature an integrated high-side protection against short-circuits, enabling the device to safely operate across a wide range of voltage levels. The high-frequency PWM support feature eliminates the spectrum of switching noise, allowing for direct connection to the device.

The chip comprises of two low-side drivers and two high-side drivers, suitable for forward/reverse-biased applications up to 20V. These low-side drivers comprise of two independent low-side drivers with TTL compatible logic input and two output options, enabling the installation of different MOS-FETs according to load requirements. The high-side drivers feature the same logic input, providing high-side control signals up to 10V with low soft-start current.

In addition to its solid driver capability, the LM5110-1SD/NOPB also features a voltage regulator circuitry to precisely control the voltage level at the low side. This allows for greater control of the power output, in terms of both current and voltage, which is necessary for several power management applications. The enhanced protection circuitry also works in tandem with the voltage regulator to ensure a reliable and stable operation of the device.

The LM5110-1SD/NOPB is a highly versatile gate driver with a wide range of applications. In addition to controlling power outputs from the DC/DC converter to the main processor, the LM5110-1SD/NOPB can also be used for phase shifting applications, controlling the pulse duration in cases of DC to AC conversion, regulating light intensity in LED drivers, and actuating modern engine control systems. Due to its low-power performance and accuracy, the LM5110-1SD/NOPB is frequently used in the discrete field, where it precisely controls the flow of current to the power MOSFETs or IGBTs.

The LM5110-1SD/NOPB is a strong gate driver that can easily control high-side and low-side drivers without excess current consumption. Furthermore, its voltage regulator capability makes it an ideal solution for applications requiring precise, regulated power delivery.
