LM5100CMAX

Overview

The LM5100CMAX is a half-bridge gate driver manufactured by Texas Instruments, designed for driving N-channel MOSFETs. It 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. The device features independent drive channels in an 8-pin SOIC package. Typical switching performance includes a rise time of 990ns and a fall time of 715ns. It supports surface-mount installation and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side drive outputs for half-bridge configurations
• Supports direct interface with standard logic levels including TTL compatibility
• Engineered for robust operation in industrial and automotive environments

Applications

• Industrial motor control systems
• Automotive power management circuits
• DC-DC converter topologies requiring half-bridge drivers

Procurement Notes

Verify the specific suffix 'MAX' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration. Cross-reference the component marking code with the latest production data to avoid counterfeit risks. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a dedicated half-bridge driver with independent channel control is required for N-channel MOSFETs. The 9V to 14V supply range suits applications powered by standard 12V systems. Consider the 990ns rise time for switching frequency limitations in the target design. Verify that the SOIC-8 package dimensions fit the available PCB footprint constraints.
