LM5111-2M

Overview

The LM5111-2M/NOPB is a dual low-side gate driver from Texas Instruments designed for driving N-channel MOSFETs. It features a compound driver architecture with independent outputs capable of sourcing and sinking up to 5 A peak current. The device operates within a supply voltage range of 3.5 V to 14 V and supports inverting logic inputs with thresholds of 0.8 V (VIL) and 2.2 V (VIH). Typical propagation delays are characterized by rise and fall times of 14 ns and 12 ns, respectively. It is housed in an 8-pin SOIC package and functions reliably across an operating temperature range of -40°C to 125°C.

Feature Summary

• Dual independent low-side channel configuration for simultaneous MOSFET control
• High peak output current capability of 5 A for rapid switching transitions
• Integrated overvoltage protection mechanisms for enhanced circuit reliability

Applications

• Synchronous buck converter topologies requiring precise low-side drive
