LM5108DRCR

Overview

The LM5108DRCR is a robust and compact half-bridge gate driver manufactured by Texas Instruments. It features a high-side and low-side output configuration with a peak output current of 2.6 A. The device supports a bus voltage up to 110 V and operates within a supply voltage range of 5.5 V to 16 V. Key timing parameters include a propagation delay of 20 ns, a rise time of 11 ns, and a fall time of 8 ns. It utilizes TTL-compatible input logic and includes enable and interlock inputs for enhanced control. The component is housed in a 10-VSON package with an exposed pad and is rated for operation between -40°C and +125°C.

Feature Summary

• Integrated high-side and low-side drivers capable of handling negative voltage at the HS pin
• TTL-compatible input logic with dedicated enable and interlock functions
• Fast switching performance with specified rise and fall times

Applications

• High-voltage power conversion systems
• Industrial motor control applications
• Inverter circuits requiring half-bridge topologies

Procurement Notes

Verify the specific ordering suffix 'DRCR' against the manufacturer's official documentation to confirm the tape-and-reel packaging quantity and variant status. Ensure that the selected package type matches the required PCB footprint and thermal dissipation design. Cross-reference the RoHS compliance details provided in the datasheet to meet environmental regulatory requirements for the intended production run.

Selection Notes

Select this component when a single-chip solution for driving both high-side and low-side switches is required. The integrated interlock feature simplifies protection logic compared to discrete driver combinations. Consider the 10-VSON package size and thermal characteristics relative to available board space and heat sinking capabilities during the initial design phase.

Part Context

The LM5108DRCR belongs to the LM5108 family of half-bridge drivers from Texas Instruments. This series is designed for applications demanding high reliability and compact form factors. The DRCR suffix specifically denotes the reel-based packaging format, distinguishing it from other variants such as the DRCT which may have different shipping specifications while maintaining identical electrical performance.

Replacement Considerations

Public confirmed substitute part numbers include LM5108DRCT.
