LM5110-2MX/NOPB

Overview

The LM5110-2MX/NOPB is a dual-channel low-side MOSFET gate driver manufactured by Texas Instruments. It features two independent drivers with peak output currents of 5A and 3A, respectively. The device operates within a supply voltage range of 3.5V to 14V and supports TTL logic inputs. It is housed in an 8-SOIC package (0.154" width) and is designed for surface-mount installation. The component functions as an inverting driver with rise and fall times of 14ns and 12ns, operating across a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel configuration providing independent control for two low-side N-channel MOSFETs
• Asymmetric output current capability delivering 5A source and 3A sink currents
• Inverting logic interface compatible with standard TTL input levels
• Robust thermal performance supporting operation up to 125°C junction temperature

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring independent channel drive
• General-purpose power management applications utilizing N-channel MOSFETs

Procurement Notes

Verify the specific suffix 'MX' corresponds to the 8-SOIC package variant when sourcing. Confirm that the '-NOPB' designation ensures compliance with RoHS standards and absence of hazardous substances. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and traceability for industrial-grade components.

Selection Notes

Select this component when asymmetric drive strength is required for different load characteristics on separate channels. The inverting configuration necessitates careful consideration of input signal polarity relative to the control logic. Verify that the 14V maximum supply voltage aligns with the system's available rail and that the SOIC footprint fits the target PCB layout constraints.

Part Context

This part belongs to the LM5110 series of dual low-side gate drivers from Texas Instruments. It shares functional similarities with other members like the LM5110-1SD but differs in package type and pinout. The series is designed for efficient driving of external N-channel MOSFETs in power conversion systems, offering a balance between drive strength and simplicity for cost-sensitive designs.

Replacement Considerations

LM5110-1SD/NOPB offers similar electrical performance in a WSON-10 package. LM5110-3SD/NOPB provides non-inverting logic options in a WSON-10 package. Cross-reference pinouts and thermal pads carefully when substituting packages.
