LM5102SD

Overview

The LM5102SD is a high-voltage half-bridge gate driver manufactured by National Semiconductor. It features programmable dead-time delay to optimize switching performance and prevent shoot-through in half-bridge configurations. The device is designed for driving power MOSFETs or IGBTs with robust output currents. It operates within a specified voltage range suitable for industrial applications.

Feature Summary

• High-voltage half-bridge gate driver architecture
• Programmable dead-time delay control
• Robust output drive capability for power switches

Applications

• Industrial motor drives
• Power supply inverters
• Isolated gate driving circuits

Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the specific suffix (e.g., NOPB) for RoHS compliance if required. Ensure the package type matches the PCB footprint requirements. Check for obsolescence status given the acquisition timeline.

Selection Notes

Select this component when a dedicated half-bridge driver with adjustable dead-time is required. Consider input logic compatibility and operating voltage range against the target power stage. Evaluate thermal management needs based on switching frequency and load conditions.

Part Context

This part belongs to the LM510x series of high-voltage gate drivers. It serves as a bridge driver solution for medium-power applications. The SD package indicates a small outline dual in-line configuration suitable for through-hole mounting.

Replacement Considerations

• LM5102SD/NOPB
• LM5104
