LM5111-1MX/NOPB

Overview

The LM5111-1MX/NOPB is a low-side MOSFET gate driver from Texas Instruments, housed in an 8-SOIC package. It features a single channel with inverting logic configuration. The device supports a supply voltage range of 3.5 V to 14 V and delivers peak output currents of 5 A source and 3 A sink. It operates within a temperature range of -40°C to +125°C TJ.

Feature Summary

• Provides high-current drive capability for efficient switching of N-channel MOSFETs
• Features inverting logic input for flexible control interface integration
• Designed for robust operation across extended industrial temperature ranges

Applications

• Low-side power switching in DC-DC converters
• Motor control applications requiring direct MOSFET drive
• General-purpose power management circuits

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status as per official datasheets. Confirm the '1M' designation corresponds to the single-channel variant rather than dual-channel versions like '2M'. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a single low-side driver with moderate current capability is required. Compare against dual-channel variants if space efficiency allows for multiple drivers in one package. Verify that the 14 V maximum supply voltage aligns with your gate drive circuit design constraints.
