Overview
The LM5100MX is a high-voltage half-bridge gate driver manufactured by Texas Instruments, designed to drive N-channel MOSFETs in power conversion applications. It features independent high-side and low-side outputs with a peak output current of 2 A. The device operates within a supply voltage range of 9 V to 14 V and supports logic input levels compatible with CMOS standards. Key electrical parameters include a typical rise time of 570 ns and fall time of 430 ns, with propagation delays under 20 ns. It functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Provides independent high-side and low-side gate drive capabilities for half-bridge configurations.
- Delivers 2 A peak source and sink current to ensure fast switching transitions.
- Supports high-voltage operation suitable for driving N-channel MOSFETs in demanding environments.
Applications
- High-frequency DC-DC converters
- Motor control systems
- Industrial power supplies
Procurement Notes
Verify the specific suffix 'MX' against the official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status if required by the end product regulations. Cross-reference ordering information directly with Texas Instruments documentation to avoid discrepancies.
Selection Notes
Select this component when a robust 2 A driver is needed for high-voltage half-bridge topologies. Consider the SOIC or similar surface-mount package availability for assembly. Evaluate the 9 V to 14 V operating range against the system's available supply rails. Verify that the propagation delay characteristics meet the timing constraints of the application.
Part Context
The LM5100 series includes variants such as LM5100A (3 A) and LM5100B (2 A), offering different drive strengths. The LM5100MX specifically denotes a variant within this family, likely featuring specific packaging or testing criteria defined by TI. It serves as a core component in power management IC portfolios for industrial and automotive sectors.
Replacement Considerations
LM5100BSDX/NOPB: Verified alternative with identical 2 A drive capability and WSON-10 packaging. LM5100CMAX: Verified alternative with 1 A drive capability and SOIC-8 packaging. Check pinout and package dimensions before substitution.
