LM5101AMRX/NOPB

Overview

The LM5101AMRX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates high-side and low-side drivers capable of controlling external N-channel power MOSFETs in bridge configurations. The device supports supply voltages up to 100 V and delivers peak output currents of 3 A for both the high-side and low-side channels. Key electrical parameters include a maximum propagation delay of 26 ns, rise times of 430 ns, and fall times of 260 ns. It operates within an extended temperature range from -40°C to +125°C and is housed in an 8-pin WSON package.

Feature Summary

• Integrates independent high-side and low-side drivers with bootstrap diode
• Supports wide input voltage range up to 100 V
• Provides high peak drive current for fast switching
• Includes under-voltage lockout protection

Applications

• High-voltage motor control systems
• Industrial power conversion circuits
• Isolated DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'AMRX' against the official Texas Instruments datasheet to confirm the exact tape-and-reel packaging quantity and material specifications. Ensure the component matches the required operating temperature range and pin configuration for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and authenticity.

Selection Notes

Select this component when designing circuits requiring isolated or non-isolated half-bridge driving with high voltage tolerance. Consider the 3 A output current capability for driving larger MOSFETs efficiently. Evaluate the 26 ns propagation delay for timing-sensitive applications. Compare against other LM5101 variants if different packaging options like SOIC are preferred over WSON.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers designed for robust performance in demanding power electronics environments. The family offers integrated solutions for driving external FETs, simplifying design compared to discrete driver implementations. The LM5101 series is widely used in industrial and automotive applications requiring reliable high-side switching capabilities.

Replacement Considerations

Compatible substitutes include LM5101AMX/NOPB and LM5101ASDX-1/NOPB. Verify pin compatibility and electrical specifications before substitution.
