The LM5101CMAX/NOPB is an advanced gate driver integrated circuit (IC) from Texas Instruments Incorporated. The LM5101CMAX/NOPB is designed to drive power MOSFETs and IGBTs in low- and high-power systems. This gate driver is ideal for applications such as variable speed drive systems and isolated converters. The LM5101CMAX/NOPB includes integrated logic gates and a simple programmable latch circuit, which allow it to be used as a stand-alone gate driver or as part of a larger system. The LM5101CMAX/NOPB is available in a compact 8-pin Small Outline IC (SOIC) package, making it suitable for use in space-constrained applications.

The LM5101CMAX/NOPB’s key features include a wide operating voltage range of 7.5V to 100V, a programmable output gain range of 0.25V/V to 2.4V/V, an output slew rate of 0.8V/µs, and an adjustable over-current limit of 0.15V to 8V. The LM5101CMAX/NOPB also offers high-speed operation, with a propagation delay of 65ns, and high-frequency switching of 2MHz. The LM5101CMAX/NOPB is available in four operating configurations: “Enable”, “High-Side”, “Low-Side”, and “Non-Inverting”.

The LM5101CMAX/NOPB is a PMIC - Gate Driver that offers a wide range of features, making it an ideal choice for sophisticated power MOSFET and IGBT power converter applications. The LM5101CMAX/NOPB’s programmable output gain and over-current limit enable it to be adjusted for different design requirements. Additional features such as its wide operating voltage range and high-speed switching make it well suited for high-power applications.

The LM5101CMAX/NOPB is a single-channel IC, which includes a logic gate and latch circuitry that are used to drive power MOSFETs and IGBTs. The logic gate and latch circuitry allow the gate driver to serve as a stand-alone driver, or as part of a larger system. The LM5101CMAX/NOPB provides up to 500mA of gate drive current and up to 4kV of transient peak voltage, making it suitable for low- and high-power applications.

In order to use the LM5101CMAX/NOPB gate driver, it is necessary to connect its input and output pins. The inputs consist of two control pins (EN and CS) and three gate pins (Hi, Lo, and Ni). The EN and CS pins are used to control the gate driver’s output, while the Hi, Lo, and Ni pins are used to configure the output drive signal. The output of the LM5101CMAX/NOPB is delivered through two output pins (VO and GND), which are connected to the power MOSFET or IGBT.

The working principle of the LM5101CMAX/NOPB is based on the fact that its inputs can be used to control its outputs. When the EN and CS pins are not in a low state (logic 0), the gate driver is enabled and its outputs can be used to drive an IGBT or power MOSFET. The Hi, Lo, and Ni pins can then be configured to provide the desired output drive signal.

The LM5101CMAX/NOPB is an advanced gate driver IC that is suitable for a wide range of applications, making it an excellent choice for high-power systems. Its programmable output gain and over-current limit enable it to be adjusted for different design requirements. The LM5101CMAX/NOPB also offers a wide operating voltage range and high-speed switching, making it well suited for a variety of power MOSFET and IGBT applications.
