LM5107MA/NOPB

Overview

The LM5107MA/NOPB is a half-bridge MOSFET gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 8 V to 14 V and delivers a peak output current of 1.4 A. The device features independent high-side and low-side drivers with TTL logic compatibility. Key timing parameters include a maximum propagation delay of 56 ns, rise time of 15 ns, and fall time of 15 ns. It functions reliably across an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Provides independent high-side and low-side gate drive outputs for efficient half-bridge configurations
• Supports fast switching speeds with 15 ns rise and fall times to minimize power loss
• Compatible with standard TTL logic input levels for straightforward control interface

Applications

• High-frequency DC-DC converter topologies requiring isolated or bootstrap drive
• Motor control systems driving half-bridge MOSFET stages
• Industrial power supplies utilizing synchronous rectification

Procurement Notes

Verify the specific suffix 'MA' corresponds to the SOIC-8 tube packaging variant when sourcing. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before integration into production designs.

Selection Notes

Select this component when a moderate peak drive current of 1.4 A is sufficient for the target MOSFET gate charge requirements. It is suitable for applications where a wide common-mode voltage range up to 100 V is needed but higher current capabilities are not required. Consider the SOIC-8 package constraints for thermal management and PCB layout space compared to larger packages offering better heat dissipation.

Part Context

This device belongs to the LM5107 family of half-bridge drivers designed for robust performance in noisy industrial environments. It serves as a bridge between low-voltage control logic and high-voltage power switches. The non-inverting configuration simplifies control scheme implementation by maintaining signal polarity through the driver stage.

Replacement Considerations

LM5107MAX/NOPB offers identical electrical specifications but utilizes an MSOP-8 package instead of SOIC-8.
