LM5111-4MX/NOPB

Overview

The LM5111-4MX/NOPB is a dual-channel low-side gate driver from Texas Instruments, designed for driving N-channel MOSFETs. It operates within a supply voltage range of 3.5 V to 14 V and delivers peak output currents of 5 A source and 3 A sink. The device features an inverting logic configuration with rise and fall times of 14 ns and 12 ns, respectively. It is housed in an 8-SOIC package and supports junction temperatures from -40 °C to +125 °C.

Feature Summary

Dual-channel architecture providing independent control for two low-side switches
High peak drive capability supporting fast switching transitions
Inverted input logic simplifies interface with standard control signals

Applications

Low-side switching in synchronous buck converters
Half-bridge and full-bridge power stage drivers
General-purpose high-speed MOSFET control circuits

Procurement Notes

Verify the specific suffix '4MX' against official Texas Instruments documentation to confirm pinout and electrical characteristics match the standard LM5111 family. Ensure the NOPB designation confirms lead-free and RoHS compliance status as per current manufacturing standards before finalizing procurement specifications.

Selection Notes

Select this component when dual isolated low-side drive is required with moderate speed requirements. The 8-SOIC package offers a balance between thermal performance and board space. Consider the 14 ns/12 ns transition times for applications where EMI constraints allow faster switching than slower alternatives.

Part Context

Part of the LM5111 series, which provides robust low-side gate driving solutions. This series is commonly integrated into power management ICs for DC-DC conversion systems. The device complements other TI components like the LM5119 controller for complete power stage design.
