LM5112SD

Overview

The LM5112SD is a low-side gate driver from Texas Instruments designed for driving N-channel MOSFETs. It features a single channel with inverting and non-inverting inputs, housed in a compact 6-WSON package. The device supports a supply voltage range of 3.5V to 14V and delivers peak output currents of 7A source and 3A sink. Typical propagation delays are characterized by rise and fall times of 14ns and 12ns respectively. It operates within a junction temperature range of -40°C to 125°C.

Feature Summary

• Provides dual logic inputs (inverting and non-inverting) for flexible control configurations
• Capable of high-speed switching with controlled rise and fall times
• Designed for robust operation in automotive environments with AEC-Q100 qualification

Applications

• Automotive power management systems
• Low-side MOSFET switching applications
• General-purpose power conversion circuits

Procurement Notes

Verify the specific suffix 'SD/NOPB' against official datasheets to confirm package type and lead-free status. Ensure compatibility with required operating temperatures and input logic levels before integration. Cross-reference part numbers with manufacturer databases to avoid obsolete or variant mismatches.

Selection Notes

Select this component when a single-channel low-side driver with dual inputs is required. Consider the 7A/3A current capability for moderate load switching. Verify that the 6-WSON package fits the PCB layout constraints and that the 3.5V-14V supply range matches the system design.

Part Context

Part of the LM511x series of gate drivers from Texas Instruments. This series focuses on efficient power switching solutions. The LM5112 specifically targets applications requiring isolated or non-isolated low-side drive with high speed and reliability standards.

Replacement Considerations

Check for direct equivalents like LM5112Q1SD/NOPB for automotive grade requirements. Verify pinout and electrical specifications against other low-side drivers in the LM511x family.
