LM5101AMX

Overview

The LM5101AMX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers in an SOIC-8 package. The device supports supply voltages from 9 V to 14 V and delivers a peak output current of 3 A. Key electrical parameters include a maximum propagation delay of 26 ns, rise time of 430 ns, and fall time of 260 ns. It operates within a junction temperature range of -40°C to +125°C and features TTL-compatible logic inputs.

Procurement Notes

Verify the complete part number including suffixes such as NOPB when sourcing. Confirm the package type is SOIC-8 and ensure compatibility with the required operating temperature range. Check datasheet specifications for supply voltage limits and output current ratings before integration into designs.

Selection Notes

Select this component for applications requiring a single-chip solution for half-bridge driving. Ensure the design accommodates the 9 V to 14 V supply voltage range. Consider the 3 A output current capability for load requirements. Verify that the SOIC-8 package fits the PCB layout constraints and thermal management needs.

Part Context

The LM5101A series includes variants with different output currents, such as 2 A and 1A options. Other packages like WSON-8 are available for space-constrained designs. The family shares similar functional characteristics but differs in performance metrics and physical footprint.

Replacement Considerations

LM5101BMAX/NOPB offers 2 A output current. LM5101ASDX-1/NOPB provides 3 A output in a WSON-8 package with faster switching times.
