LM5110-2M/NOPB

Overview

The LM5110-2M/NOPB is a dual low-side gate driver manufactured by Texas Instruments in an SOIC-8 surface-mount package. It provides independent control for two channels with output currents of -5 A and 3 A. The device operates within a supply voltage range of 3.5 V to 14 V and supports TTL logic inputs. Key electrical parameters include a rise time of 25 ns, fall time of 12 ns, and maximum delay times of 12 ns. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent low-side drive capabilities
• Asymmetric output current strength supporting varied load requirements
• TTL-compatible input logic for direct microcontroller interfacing
• Extended thermal operation suitable for demanding industrial environments

Applications

• Low-side switching for power MOSFETs in DC-DC converters
• Gate driving for IGBT modules in motor control systems
• Power management circuits requiring isolated or non-isolated low-side control

Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-8 package variant distinct from WSON versions. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering part number matches the required channel configuration and pinout. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement.

Selection Notes

Select this component when asymmetric drive currents are necessary for optimizing switching performance. The dual-channel design simplifies board layout compared to single drivers. Verify that the operating voltage range aligns with the system's power supply rails. Consider the thermal characteristics if high-frequency switching is anticipated in enclosed spaces.

Part Context

This device belongs to the LM5110 family of compound gate drivers designed for robust power switching applications. It complements other variants like the LM5110-2SD/NOPB which utilizes a different package footprint. The series focuses on providing reliable low-side control with integrated features to enhance system efficiency and reduce component count in power stages.

Replacement Considerations

LM5110-2SD/NOPB offers identical electrical specifications but utilizes a WSON-10 package instead of SOIC-8. Substitution requires verifying PCB footprint compatibility and reflow profile adjustments. No functional changes are expected between these package variants.
