LM5101ASDX

Overview

The LM5101ASDX is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers capable of sourcing and sinking 3 A peak output current. The device supports supply voltages from 7.5 V to 14 V and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a rise time of 10 ns and a fall time of 10 ns. It utilizes TTL-compatible logic inputs and is housed in an 8-pin WSON package.

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation, as variations such as NOPB or ASDX may indicate distinct packaging or revision levels. Confirm RoHS compliance status and ensure the procurement channel provides authentic components with traceable manufacturing data to avoid counterfeit risks.

Selection Notes

Select this component when a 3 A drive current is required for high-side and low-side MOSFETs in half-bridge applications. Ensure the input logic voltage aligns with TTL standards and that the PCB layout accommodates the thermal requirements of the WSON-8 package under maximum load conditions.

Part Context

This part belongs to the LM5101A series of high-voltage gate drivers. It shares functional similarities with other variants like the LM5101CMYE/NOPB but differs in output current capacity and package type. The series is designed for robust performance in demanding power electronics environments requiring precise timing and high current drive.

Replacement Considerations
