LM5101AM/NOPB

Overview

The LM5101AM/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of driving N-channel MOSFETs with a peak output current of 3 A. The device operates within a supply voltage range of 9 V to 14 V and supports TTL logic inputs. Key electrical parameters include a maximum propagation delay of 26 ns, rise time of 430 ns, and fall time of 260 ns. It functions reliably across an operating temperature range from -40°C to +125°C TJ.

Feature Summary

• Provides independent high-side and low-side gate drive signals for half-bridge configurations.
• Delivers 3 A source and sink output current capability for fast MOSFET switching.
• Compatible with standard TTL logic input levels for direct interface control.

Applications

• High-side and low-side power stage driving in DC-DC converters
• Half-bridge and full-bridge inverter circuits
• Motor control applications requiring isolated or floating gate drive

Procurement Notes

Verify the specific suffix 'AM' indicates the tube packaging variant rather than tape and reel when ordering. Confirm that the NOPB designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure correct revision level and availability status prior to procurement.

Selection Notes

Select this component when a robust 3 A gate driver is required for high-voltage half-bridge topologies. The wide operating temperature range makes it suitable for industrial environments. Ensure the application voltage does not exceed the 118 V rating and that the logic interface matches the specified TTL requirements for reliable signal transmission.

Part Context

This device belongs to the LM5101 family of high-voltage gate drivers designed for power management applications. It serves as a critical interface between low-voltage control logic and high-power switching elements. The SOIC-8 package provides a compact solution for space-constrained designs while maintaining thermal performance through the exposed pad.

Replacement Considerations

LM5101AMX/NOPB: Identical functional specifications but supplied in tape-and-reel packaging instead of tubes. LM5101ASD/NOPB: Same electrical characteristics but housed in a smaller SDIP-8 package. LM5101ASDX-1/NOPB: Features identical performance metrics but utilizes a WSON-8 package for surface-mount applications.
