LM5106SD Description

The LM5106SD from Texas Instruments is a high-voltage half-bridge gate driver designed for synchronous power MOSFET and IGBT applications. Housed in a compact 10-WSON package, it supports a voltage supply range of 8V to 14V, making it suitable for high-efficiency power conversion systems. With a maximum bootstrap voltage of 118V, it ensures robust high-side switching performance. The device is obsolete but remains relevant for legacy designs requiring high-speed switching with 15ns rise and 10ns fall times, minimizing switching losses.

LM5106SD Features

• Dual-Channel Driver: Two independent drivers (1.2A source, 1.8A sink) for precise control of high- and low-side switches.
• Fast Switching: Optimized 15ns/10ns rise/fall times enhance efficiency in high-frequency applications.
• Wide Voltage Range: Supports 8V–14V logic supply and 118V bootstrap capability for high-voltage designs.
• Robust Logic Interface: 0.8V (VIL) and 2.2V (VIH) thresholds ensure compatibility with low-voltage controllers.
• Surface-Mount Packaging: 10-WSON (Tape & Reel) enables space-constrained PCB layouts.
• REACH Unaffected: Compliant with environmental regulations, suitable for industrial use.

LM5106SD Applications

• Motor Drives: Ideal for brushless DC (BLDC) and stepper motor control due to fast switching and high current drive.
• Switch-Mode Power Supplies (SMPS): Enhances efficiency in synchronous buck/boost converters.
• Solar Inverters: High-voltage tolerance suits photovoltaic MPPT and inverter stages.
• Industrial Power Systems: Used in UPS, welding equipment, and industrial automation for reliable switching.

Conclusion of LM5106SD

The LM5106SD excels in high-voltage, high-speed switching applications, offering low propagation delays and strong gate drive currents. While obsolete, its synchronous half-bridge architecture and compact form factor make it a viable choice for legacy or niche designs requiring robust performance in motor control, power conversion, and renewable energy systems. Engineers should evaluate alternatives for new designs but can leverage its proven reliability in existing implementations.
