LM5104SDX

Overview

The LM5104SDX is a half-bridge gate driver manufactured by Texas Instruments, designed for high-side and low-side MOSFET or IGBT control. It operates within a supply voltage range of 9 V to 14 V and delivers an output current of 1.8 A. The device features propagation delays up to 56 ns, with rise and fall times of 600 ns. It supports CMOS logic inputs and functions at temperatures from -40°C to +125°C. Packaged in a WSON-10 format, it integrates synchronous drive capabilities for efficient power management applications.

Feature Summary

• Integrates dual drivers for simultaneous high-side and low-side switching control
• Supports synchronous operation with CMOS-compatible logic input thresholds
• Provides robust thermal performance across extended industrial temperature ranges

Applications

• High-frequency DC-DC converter topologies
• Half-bridge power stage driving
• Industrial motor control systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability as distribution channels may list obsolete or discontinued variants. Ensure the component matches the required WSON-10 footprint and electrical specifications for the target design.

Selection Notes

Select this component when a compact half-bridge solution with moderate speed is required. Evaluate the 1.8 A peak current capability against load requirements. Consider the 600 ns transition times for EMI constraints. Verify that the 9 V to 14 V supply range aligns with the system's available power rails.

Part Context

This part belongs to the LM510x family of gate drivers from Texas Instruments. It serves as a non-isolated driver for power stages. The SDX designation indicates a specific reel packaging configuration within the WSON-10 product line, distinct from other suffixes like NOPB which may denote environmental compliance variations.
