Gate Drivers ICs

LM5100AM/NOPB Description

The LM5100AM/NOPB from Texas Instruments is a high-performance half-bridge gate driver IC designed for robust power MOSFET and IGBT control. Operating within a 9V to 14V supply range, it features independent high- and low-side drivers, enabling precise switching in high-voltage applications. With a maximum bootstrap voltage of 118V, it supports high-side driving in demanding power topologies. The device delivers 3A peak output current (source/sink), ensuring fast switching with 430ns rise and 260ns fall times (typical), minimizing switching losses. Packaged in an 8-pin SOIC, it is RoHS3 compliant and suitable for surface-mount applications.

LM5100AM/NOPB Features

• Independent High/Low-Side Drivers: Enables flexible half-bridge or full-bridge configurations.
• High-Side Voltage Support (118V Max): Ideal for high-voltage applications like motor drives and inverters.
• Fast Switching (430ns Rise / 260ns Fall): Reduces power dissipation and improves efficiency.
• 3A Peak Output Current: Ensures strong gate drive for fast turn-on/off of power switches.
• Wide Supply Range (9V–14V): Compatible with standard power supplies.
• Robust Packaging (8-SOIC): Compact and suitable for space-constrained designs.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.

LM5100AM/NOPB Applications

The LM5100AM/NOPB excels in high-voltage, high-frequency switching systems, including:

• Motor Drives: Precision control in brushed/BLDC motor applications.
• Switch-Mode Power Supplies (SMPS): Enhances efficiency in buck/boost converters.
• DC-DC Converters: Optimizes performance in isolated/non-isolated topologies.
• Solar Inverters: Reliable gate driving for photovoltaic systems.
• Industrial Power Systems: Suitable for UPS, welding equipment, and industrial automation.

Conclusion of LM5100AM/NOPB

The LM5100AM/NOPB stands out as a high-reliability gate driver for demanding power electronics, combining fast switching, high voltage tolerance, and strong drive capability. Its independent channel design and compact SOIC package make it versatile for motor control, power conversion, and renewable energy systems. While it is in Last Time Buy status, its performance and compliance with RoHS3/REACH ensure it remains a preferred choice for legacy and new designs requiring robust half-bridge driving solutions.
