LM5110-1M

Overview

The LM5110-1M is a dual low-side gate driver manufactured by Texas Instruments, designed for high-performance power switching applications. It features two independent drivers with a peak output current of 5 A per channel. The device operates within a supply voltage range of 3.5 V to 14 V and supports non-inverting logic configurations. Key electrical parameters include a typical rise time of 14 ns and a fall time of 12 ns. It is rated for an operating temperature range from -40°C to +125°C. The component is housed in a WSON-10 package, providing a compact solution for driving MOSFETs in synchronous rectification and isolated converter topologies.

Feature Summary

• Dual independent low-side gate driver channels
• Negative output voltage capability for bootstrap operation
• Non-inverting logic input configuration
• Compact surface-mount packaging

Applications

• Synchronous buck converters
• Isolated DC/DC converters
• Half-bridge and full-bridge topologies
• Motor drive circuits

Procurement Notes

Verify the specific suffix 'M' against the official datasheet to confirm material composition and lead-free status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm availability and any potential design changes or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a dual low-side driver with moderate speed and 5 A peak current is required. It is suitable for applications where negative voltage handling at the output is necessary for reliable bootstrap capacitor charging. Consider thermal performance and package size constraints relative to the WSON-10 footprint. Evaluate if the 14 ns rise time meets the switching frequency requirements of the target power stage.

Part Context

The LM5110 belongs to the family of compound gate drivers from Texas Instruments, often associated with National Semiconductor heritage products. It serves as a complementary driver to high-side counterparts like the LM5112. The 'M' suffix typically denotes a specific material or package variation within the broader LM5110 series, distinguishing it from other variants such as the LM5110-1SD.
