LM5109BSD/NOPB

Gate Driver Overview

The LM5109BSD/NOPB is a high-voltage half-bridge 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 A. The device features independent high-side and low-side drivers with propagation delays up to 32 ns, rise/fall times of 15 ns, and turn-on/turn-off delays of 2 ns. It functions in temperatures from -40°C to +125°C using an LLP-8 surface-mount package.

Gate Driver Feature Summary

Provides independent high-side and low-side gate drive outputs for half-bridge configurations
Supports TTL logic input levels for direct interface with standard control signals
Operates reliably across extended industrial temperature ranges

Gate Driver Applications

High-voltage MOSFET switching applications
Half-bridge power converter topologies
Industrial motor control systems

Gate Driver Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the LLP-8 package variant matches the required footprint for PCB layout. Ensure the operating voltage requirements align with the 8 V to 14 V specification before integration into the design.

Gate Driver Selection Notes

Select this component when a compact half-bridge driver with moderate 1 A peak current capability is required. It is suitable for designs needing independent channel control and TTL compatibility. Consider the LLP-8 package size constraints and the specific voltage range limitations compared to higher voltage alternatives.

Gate Driver Part Context
