LM2101DR

Overview

The LM2101DR is a half-bridge gate driver manufactured by Texas Instruments, designed for driving power MOSFETs and GaN FETs. It operates within a supply voltage range of 9 V to 18 V and delivers peak output currents of 0.5 A for the high-side and 0.8 A for the low-side channels. The device is housed in an SOIC-8 surface-mount package and supports non-inverting logic configurations. It functions reliably across an extended temperature range from -40 °C to +125 °C, ensuring robust performance in demanding industrial and automotive applications.

Feature Summary

• Integrated half-bridge topology with asymmetric drive strength for optimized switching
• Robust thermal operation capability across wide ambient temperature extremes
• Surface-mount packaging suitable for automated PCB assembly processes

Applications

• Industrial motor control systems
• Power factor correction circuits
• DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-8 tape-and-reel packaging configuration when sourcing components. Confirm that the operating voltage requirements align with the specified 9 V minimum threshold to ensure proper internal biasing. Validate that the target application environment remains within the stated -40 °C to +125 °C operational limits to maintain device reliability and performance specifications.

Selection Notes

Select this component when a dedicated half-bridge driver is required for medium-power switching applications. Consider the asymmetric current capabilities if distinct high-side and low-side drive strengths are necessary for optimizing switching losses. Ensure the input logic levels are compatible with standard CMOS or TTL interfaces before integration into the control circuitry.
