LM5101BSD/NOPB

Overview

The LM5101BSD/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers designed for driving N-channel power MOSFETs in hard-switching applications. The device operates with a supply voltage range of 9 V to 14 V and delivers a peak output current of 2 A. Key electrical parameters include a maximum propagation delay of 26 ns, a rise time of 570 ns, and a fall time of 430 ns. It functions within an operating temperature range of -40°C to +125°C and is housed in a WSON-10 package.

Feature Summary

• Integrates independent high-side and low-side drivers for half-bridge topologies
• Provides robust drive capability with 2 A peak source and sink currents
• Features non-inverting logic inputs for straightforward control interface

Applications

• Hard-switching DC/DC converters
• Synchronous rectification circuits
• Motor control systems

Procurement Notes

Verify the specific suffix 'BSD' against the manufacturer's official documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the WSON-10 package. Cross-reference the datasheet revision date to confirm the validity of the electrical characteristics provided.

Selection Notes

Select this component when a compact solution for driving N-channel MOSFETs in half-bridge configurations is required. The 2 A output current is suitable for medium-power applications. Consider the WSON-10 package size constraints and the thermal performance requirements for the intended operating environment.

Part Context

This part belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. The family includes variants with different output currents (1 A, 2 A, 3 A) and packages (SOIC-8, WSON-8, WSON-10). The LM5101BSD/NOPB specifically denotes the 2 A version in the WSON-10 package.

Replacement Considerations

LM5101ASD/NOPB: 3 A output in WSON-8 package. LM5101AMX/NOPB: 3 A output in SOIC-8 package. Verify pinout and package dimensions before substitution.
