LM5101CSDX/NOPB

Overview

The LM5101CSDX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for driving N-channel MOSFETs. It operates within a supply voltage range of 9 V to 14 V and provides independent high-side and low-side outputs with a peak output current capability of 1 A. The device utilizes a 10-pin WSON package suitable for surface-mount applications. Key electrical characteristics include a maximum propagation delay of 26 ns, an open-drain output configuration, and non-inverting logic inputs. It functions reliably across an extended junction temperature range from -40°C to +125°C.

Feature Summary

• Independent high-side and low-side drivers configured for half-bridge topologies
• Non-inverting logic input compatibility with TTL standards
• Open-drain output architecture supporting bootstrap or isolated drive schemes

Applications

• DC-DC converter power stages
• Motor control bridge circuits
• Isolated gate drive interfaces

Procurement Notes

Verify the specific suffix 'SDX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and variant designation. Ensure the component matches the required 10-pin WSON footprint and that the 1 A output current rating aligns with the target load requirements. Cross-reference the RoHS compliance status directly with the latest production documentation.

Selection Notes

Select this component when a compact solution for driving N-channel MOSFETs in half-bridge configurations is required. The 1 A drive strength suits moderate-speed switching applications where minimal board space is critical due to the small WSON package. Consider the 9 V to 14 V operating range to ensure compatibility with the system's available supply rails and logic levels.

Part Context

This part belongs to the LM5101 family of half-bridge gate drivers from Texas Instruments. Variants within this series, such as the LM5101A and LM5101B, differ primarily in their peak output current capabilities and switching speed parameters. The LM5101C represents a specific performance tier within this lineup, offering balanced drive strength for general-purpose power management applications.

Replacement Considerations

Compatible substitutes include LM5101ASD/NOPB, LM5101BSD/NOPB, and LM5101AM/NOPB. Verify pinout compatibility and ensure the alternative variant meets the specific current and timing requirements of the design.
