Overview
The LM5111-1MYX is a dual 5A compound gate driver from Texas Instruments, designed for driving N-channel MOSFETs in low-side configurations. It operates within a supply voltage range of 3.5V to 14V and supports logic input thresholds of 0.8V (VIL) and 2.2V (VIH). The device features an inverting configuration with rise and fall times of 14ns and 12ns, respectively. It is housed in an 8-pin MSOP PowerPAD package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Dual channel output capability providing independent control for two low-side switches
- High peak output current of 5A for efficient MOSFET switching
- Integrated overvoltage protection mechanisms
- Compact thermal-enhanced MSOP PowerPAD packaging
Applications
- Low-side switching in DC-DC converter topologies
- Motor control circuits requiring robust gate drive
- Power management systems utilizing N-channel MOSFETs
Procurement Notes
Verify the specific suffix 'MYX' against the official datasheet to confirm pinout and package dimensions match your PCB footprint. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the ordering information with Texas Instruments documentation to avoid confusion with similar variants like the MX or MY packages.
Selection Notes
Select this component when a compact dual low-side driver with high current capability is required. The MSOP PowerPAD package offers a balance between size and thermal performance. Consider the inverting logic requirement and the 3.5V minimum supply voltage during system design. Verify that the 14ns/12ns switching speeds align with your target frequency and EMI constraints.
Part Context
The LM5111 series serves as a specialized gate driver solution within Texas Instruments' power management portfolio. It is part of the broader LM511x family, which includes variants with different features such as negative voltage capability. This specific model focuses on standard low-side applications, offering a cost-effective and space-efficient alternative to discrete driver solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Texas Instruments application notes or distributor databases for cross-references based on specific electrical and mechanical requirements.
