LM5100M/NOPB

Overview

The LM5100M/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers capable of sourcing and sinking 2 A peak output current. The device operates within a supply voltage range of 9 V to 14 V and supports bootstrap operation for the high-side switch. Key electrical parameters include a typical rise time of 570 ns, fall time of 430 ns, and maximum propagation delay of 20 ns. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge configurations
• Provides 2 A peak source and sink output current capability
• Supports bootstrap operation for floating high-side drive
• Features CMOS-compatible logic inputs

Applications

• High-voltage power switching applications
• Industrial motor control systems
• Power supply designs requiring isolated or floating gate drive

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the component meets RoHS compliance requirements as indicated by the NOPB suffix. Cross-reference the ordering part number with official Texas Instruments documentation to validate availability and revision status before procurement.

Selection Notes

Select this component when a robust half-bridge driver with 2 A output capability is required for high-voltage applications. Ensure the design accommodates the 9 V to 14 V supply voltage range and utilizes a bootstrap circuit for the high-side driver. Verify that the SOIC-8 package fits the PCB layout constraints and thermal requirements of the target system.

Part Context

The LM5100M/NOPB belongs to the LM5100B series of high-voltage gate drivers from Texas Instruments. This series is designed for driving N-channel power MOSFETs in half-bridge topologies. The M suffix indicates an SOIC-8 package variant, distinguishing it from other package options like WSON or MSOP within the same functional family.

Replacement Considerations

Compatible alternatives within the same family include LM5100BSD/NOPB and LM5100BMA/NOPB. These parts share identical electrical specifications but differ in package type (WSON-10 and SOIC-8 respectively). Verify pinout compatibility and thermal performance when substituting.
