LM5101MX/NOPB

Overview

The LM5101MX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers in an 8-SOIC package. The device supports supply voltages from 9 V to 14 V and delivers peak output currents of 1.8 A for sourcing and sinking. Key electrical parameters include a maximum propagation delay of 56 ns, rise and fall times of 600 ns, and operating temperatures ranging from -40°C to +125°C. It features TTL-compatible logic inputs and operates without inversion.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge configurations
• Supports high-voltage operation with integrated bootstrap functionality
• Features TTL-compatible logic inputs for direct interface with standard control signals

Applications

• High-side and low-side MOSFET driving in power conversion circuits
• Half-bridge and full-bridge converter topologies
• Motor drive applications requiring isolated gate control

Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging options such as cut tape or reel. Confirm the SOIC-8 package dimensions and thermal characteristics match your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a single IC solution is required for driving both high-side and low-side N-channel MOSFETs in a half-bridge arrangement. It is suitable for designs needing independent control of each side with minimal external components. Ensure the input logic levels are compatible with the TTL specification provided in the datasheet.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers from Texas Instruments. Variants within the family may offer different current capabilities or propagation delays, such as the LM5101A series which provides higher peak currents. The MX/NOPB designation specifically indicates the SOIC-8 package and RoHS-compliant manufacturing process.

Replacement Considerations

Direct substitutes within the same family include LM5101AMX/NOPB and LM5101BMAX/NOPB, which share the SOIC-8 package but differ in output current specifications and timing parameters. Verify pin compatibility and electrical ratings before swapping.
