LM5100CMA/NOPB

Overview

The LM5100CMA/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features two independent outputs for driving N-channel MOSFETs with a typical output current of 1 A. The device operates within a supply voltage range of 9 V to 14 V and accepts non-inverting logic inputs with a minimum high-level voltage of 2.3 V. Key timing parameters include a typical rise time of 990 ns, a fall time of 715 ns, and a maximum propagation delay of 26 ns. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides independent high-side and low-side drive capabilities for N-channel MOSFETs
• Supports non-inverting logic input compatibility
• Operates reliably across extended industrial temperature ranges

Applications

• High-side and low-side gate driving for power electronics
• Motor control applications requiring isolated switching
• Industrial power conversion systems

Procurement Notes

Verify the specific suffix 'N/PB' confirms lead-free compliance and RoHS status. Confirm the 'MA' designation corresponds to the standard SOIC-8 tube packaging variant rather than tape-and-reel options. Ensure the component matches the exact pinout and thermal characteristics defined in the official datasheet before integration.

Selection Notes

Select this component when a 1 A peak drive current is sufficient for the target load. Consider the 9 V to 14 V supply requirement against available system rails. Evaluate the 26 ns propagation delay against switching frequency needs. Compare against higher-current variants like the LM5100B or LM5100A if faster transitions or greater drive strength are required.

Part Context

This part belongs to the LM5100 family of high-voltage half-bridge drivers designed for robust power switching. It complements other variants such as the LM5100B (2 A) and LM5100A (3 A), offering a balanced solution for moderate current requirements. The series provides flexible packaging options including tube and reel configurations to suit various manufacturing processes.

Replacement Considerations

LM5100CMAX/NOPB: Identical electrical specifications but supplied in tape-and-reel packaging instead of tubes.
