LM5112MY/NOPB

Overview

The LM5112MY/NOPB is a tiny, low-side MOSFET gate driver from Texas Instruments. It features compound CMOS and bipolar outputs to reduce output current variation across temperature and voltage ranges. The device operates with a supply voltage of 3.5V to 14V and delivers peak output currents of 7A source and 3A sink. It supports inverting and non-inverting logic inputs with typical rise and fall times of 14ns and 12ns respectively. Designed for automotive applications, it holds AEC-Q100 qualification and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Compound output stage minimizes current variation over operating conditions
• Automotive grade reliability with AEC-Q100 certification
• Compact 6-WSON package for space-constrained designs

Applications

• Low-side switching in automotive power distribution systems
• DC-DC converter output stages
• Motor control applications requiring robust gate drive

Procurement Notes

Verify the specific suffix 'MY' against the official TI datasheet to confirm package type and material compliance. Ensure the 'NOPB' designation aligns with current RoHS standards. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a compact, high-current low-side driver is required for automotive environments. The compound output architecture offers superior performance consistency compared to standard CMOS drivers. Consider the 6-WSON footprint for PCB area optimization. Verify that the input logic levels match the controlling microcontroller or FPGA signals within the specified VIL and VIH thresholds.

Part Context

This device belongs to the LM511x family of gate drivers designed for high-efficiency power conversion. It complements other variants like the LM5111 and LM5112Q1 by offering a specific package configuration suitable for dense layouts. The MY suffix typically denotes a specific tape and reel or package variant within the broader LM5112 product line.

Replacement Considerations

LM5112SD/NOPB: Similar functionality but different package (WSON vs MSOP). LM5112Q1SD/NOPB: Automotive qualified version with similar electrical characteristics.
