LM5107SD

Overview

The LM5107SD/NOPB is a high-voltage half-bridge gate driver designed for driving N-channel power MOSFETs. It features a wide supply voltage range of 8 V to 14 V and delivers a peak output current of 1.4 A. The device operates within an extended temperature range from -40 °C to +125 °C. Key electrical parameters include rise and fall times of 15 ns. It is housed in an LLP-8 package.

Feature Summary

• Integrated bootstrap diode for high-side drive
• Dedicated dead-time control input
• Under-voltage lockout protection

Applications

• High-frequency synchronous rectification
• Isolated DC/DC converter front ends
• Motor control bridge drivers

Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's official datasheet to confirm RoHS compliance and exact pinout configuration. Ensure the ordering part number matches the required package variant, as minor suffix changes can indicate different reel specifications or regional certifications.

Selection Notes

Select this component when a compact solution for high-side and low-side MOSFET driving is required. The integrated bootstrap diode simplifies bill of materials by removing external components. Verify that the 1.4 A peak current capability meets the gate charge requirements of the target power switches at the intended switching frequency.

Part Context

This device belongs to the LM510x family of high-voltage gate drivers from Texas Instruments. It shares functional similarities with other members like the LM5101 but offers optimized integration for specific half-bridge topologies. The series is characterized by robust protection features and fast switching speeds suitable for modern power electronics.
