LM5109ASDX/NOPB

Overview

The LM5109ASDX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features two independent channels with non-inverting inputs, designed for driving N-channel MOSFETs. The device supports a supply voltage range of 8V to 14V and delivers a peak output current of 1A for both sourcing and sinking. It operates within a junction temperature range of -40°C to 125°C and utilizes an 8-WSON (4x4) package with a bare pad. Typical rise and fall times are 15ns each.

Feature Summary

Provides high-side and low-side drive capabilities for half-bridge configurations
Delivers symmetrical 1A peak source and sink currents for fast switching
Supports bootstrap operation for high-side voltage levels up to 108V

Applications

Industrial motor control systems
High-voltage power conversion circuits
Inverter bridge drivers

Procurement Notes

Verify the specific suffix 'SDX' against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure compatibility with the target PCB footprint for the 8-WSON package. Confirm that the non-inverting logic input requirements match the system control signals before finalizing procurement.

Selection Notes

Select this component when a robust half-bridge driver with 1A output capability is required for high-voltage applications. Consider the 108V high-side voltage limit and the 8WSON thermal performance. Evaluate if the 15ns transition times meet the system's switching frequency and EMI constraints compared to faster or slower alternatives in the family.

Part Context

This part belongs to the LM5109 family of high-voltage gate drivers from Texas Instruments. It shares core functional specifications with variants like the LM5109ASD but may differ in packaging or environmental certifications. The 'NOPB' suffix typically indicates lead-free and RoHS-compliant manufacturing, distinguishing it from older non-compliant versions.
