LM5111-2MYX

Overview

The LM5111-2MYX 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-pin MSOP PowerPAD 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 current capability to ensure fast switching transitions
• Integrated overvoltage protection mechanisms

Applications

• Synchronous buck converter designs
• Point-of-load (POL) power stages
• Industrial motor drive circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and thermal pad requirements. Ensure the selected variant matches the required operating temperature range and packaging specifications for the target application environment.

Selection Notes

Select this component when high-speed switching performance is required for low-side applications. Consider the MSOP PowerPAD package for improved thermal dissipation compared to standard SOIC packages. Verify input logic levels align with the controller's output voltage standards.

Part Context

This part belongs to the LM5111 series of compound gate drivers. It shares functional similarities with other members like the LM5111-1MY but offers dual-channel integration. The series is optimized for high-frequency power conversion topologies requiring robust gate drive signals.
