LM5108DRCT

Overview

The LM5108DRCT is a robust half-bridge gate driver manufactured by Texas Instruments, designed for high-voltage power applications. It features a VSON-10 surface-mount package and supports dual-channel operation with independent high-side and low-side outputs. The device delivers a peak output current of 2.6 A, enabling efficient switching of external MOSFETs. It operates within a supply voltage range of 5.5 V to 16 V and withstands bus voltages up to 110 V. Key timing parameters include a rise time of 11 ns and a fall time of 8 ns. The component functions reliably across an extended temperature range from -40 °C to +125 °C, utilizing CMOS logic inputs.

Feature Summary

• Integrated interlock input prevents simultaneous conduction of high-side and low-side switches
• High-voltage tolerance at the high-side pin handles negative transients down to -5 V
• CMOS-compatible input logic ensures compatibility with standard control interfaces

Applications

• Isolated DC-DC converter topologies
• Half-bridge inverter circuits
• Motor drive systems requiring high-side switching

Procurement Notes

Verify the specific suffix DRCT corresponds to the reel or cut tape packaging configuration as defined by Texas Instruments. Confirm that the ordering part number matches the required package type and thermal characteristics. Ensure compliance with RoHS standards and check for any specific handling requirements related to moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when designing circuits requiring a compact solution for driving high-voltage half-bridge configurations. The integrated interlock feature simplifies protection logic compared to discrete solutions. Consider the 2.6 A peak current capability against the gate charge requirements of the target MOSFETs to ensure adequate switching speed without excessive drive losses.

Part Context

This part belongs to the LM5108 series of half-bridge drivers from Texas Instruments. It shares functional similarities with variants such as LM5108DRCR, differing primarily in packaging format and reel specifications. The series is categorized under PMIC power management ICs, specifically within the gate drivers subcategory for isolated power conversion applications.

Replacement Considerations

LM5108DRCR serves as a direct substitute within the same product family, offering identical electrical performance but potentially differing in reel packaging specifications.
