LM5100BMAX/NOPB

Overview

The LM5100BMAX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers capable of driving external N-channel power MOSFETs. The device operates with a supply voltage range from 9 V to 14 V and delivers a typical output current of 1 A. Key electrical parameters include a maximum propagation delay of 20 ns, a typical rise time of 990 ns, and a typical fall time of 715 ns. It functions within an operating temperature range of -40°C to +125°C and is housed in an 8-pin SOIC package.

Procurement Notes

Verify the specific suffix 'B' against the official Texas Instruments datasheet to confirm exact electrical characteristics and pinout compatibility. Ensure the ordering part number matches the required package style and RoHS compliance status. Cross-reference the manufacturer's latest documentation to validate any recent design changes or obsolescence notices before finalizing procurement decisions.

Selection Notes

Select this component when a robust half-bridge solution is required for driving external N-channel MOSFETs in high-voltage applications. Consider the 1 A output drive capability and 20 ns propagation delay for switching speed requirements. Evaluate the 9 V to 14 V supply voltage range against the system's available power rails. Confirm that the SOIC-8 package fits the PCB layout constraints and thermal management needs.

Part Context

This device belongs to the LM5100 family of gate drivers from Texas Instruments. It is designed as a cost-effective solution for high-voltage power switching applications. The family typically includes variants with different drive currents and packages, such as the LM5100AM for higher current capabilities. The LM5100BMAX/NOPB specifically targets applications requiring reliable half-bridge control with standard drive strength.

Replacement Considerations

Direct substitutes may include other LM5100 family members like the LM5100CMAX/NOPB or LM5100AMX-NOPB, provided their drive currents and timing parameters meet the design requirements. Verify pin-to-pin compatibility and electrical specifications before substitution.
