LM5100CMA

Overview

The LM5100CMA is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features two independent channels designed to drive N-channel MOSFETs. The device operates within a supply voltage range of 9V to 14V and accepts non-inverting logic inputs with a minimum high-level input voltage of 2.3V. It utilizes an 8-pin SOIC package for surface mount installation. Electrical characteristics include a typical rise time of 990ns and a fall time of 715ns. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side gate drive capabilities for half-bridge configurations
• Supports direct interface with standard logic families including TTL-compatible inputs
• Engineered for robust operation across extended industrial temperature ranges

Applications

• High-side and low-side power switching applications
• Half-bridge converter topologies
• Industrial motor control systems

Procurement Notes

Verify the specific suffix 'CMA' against the manufacturer's current datasheet to confirm package type and availability status. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration. Cross-reference the date code and RoHS compliance details with the latest production announcements to guarantee component authenticity and regulatory adherence before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel driver for N-channel MOSFETs is required in a compact SOIC-8 footprint. It is suitable for designs needing independent control of high-side and low-side switches without complex bootstrap circuitry constraints. Consider the 9V to 14V supply requirement and the specific rise/fall times when evaluating compatibility with target switching frequencies and load conditions.

Part Context

The LM5100 series belongs to Texas Instruments' portfolio of high-voltage gate drivers, often grouped with variants like LM5101 and LM5100A which offer different output current capabilities. These devices are commonly used in power management integrated circuits (PMIC) subsystems. The CMA suffix typically denotes a specific mass-production variant within the broader LM5100 family, sharing core functional architecture while differing in packaging or testing specifications.
