LM5101M/NOPB

Overview

The LM5101M/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-pin SOIC package. The device supports N-channel MOSFETs with a supply voltage range of 9 V to 14 V. It delivers a peak output current of 1.8 A. Key timing parameters include a maximum propagation delay of 56 ns, rise time of 600 ns, and fall time of 600 ns. The operating junction temperature range spans from -40°C to +125°C.

Feature Summary

• Integrates independent high-side and low-side drivers for half-bridge configurations
• Supports N-channel power MOSFETs with robust 1.8 A peak drive capability
• Features non-inverting logic inputs compatible with TTL standards
• Includes under-voltage lockout protection for reliable operation

Applications

• Industrial motor control systems
• Power supply topologies requiring half-bridge switching
• Battery management system (BMS) switch drivers

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-8 narrow package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.

Selection Notes

Select this component for applications requiring isolated or floating high-side driving without external bootstrap complexity constraints. Compare against the LM5101AMX/NOPB if higher speed performance with 3 A current and faster transition times is necessary. Evaluate the LM5101ASD-1 variants if a smaller WSON footprint is preferred over the standard SOIC-8 package size.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers designed for industrial and automotive environments. It provides a cost-effective solution for driving power switches in bridge configurations. The family includes variations with different drive strengths and package options to suit diverse board space and performance requirements.

Replacement Considerations

LM5101AMX/NOPB offers higher drive current and faster switching speeds. LM5101MX/NOPB is a direct functional equivalent within the same series.
