LM5107SD/NOPB

Overview

The LM5107SD/NOPB is a half-bridge gate driver IC designed for high-voltage applications. It features a supply voltage range of 8V to 14V and supports bootstrap voltages up to 118V. The device delivers peak output currents of 1.4A for both sourcing and sinking. Typical rise and fall times are 15ns each. It operates within a junction temperature range of -40°C to +125°C. The component is housed in an LLP-8 package.

Feature Summary

• Integrated high-side and low-side drivers for synchronous half-bridge configurations
• Capable of driving N-channel MOSFETs with high peak current capability
• Non-inverting input logic compatible with standard control signals

Applications

• High-voltage motor drive systems
• Industrial power conversion circuits
• Isolated DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance when ordering. Confirm the LLP-8 package variant matches the target PCB footprint. Ensure the supplier provides official datasheets to validate electrical parameters against design requirements. Check for any recent product change notices affecting assembly sites or materials.

Selection Notes

Select this component for applications requiring robust half-bridge driving with high voltage isolation capabilities. The 1.4A peak current ensures fast switching transitions for efficient power management. Consider the 118V bootstrap limit when designing the gate drive circuit. The wide operating temperature range suits demanding industrial environments.

Part Context

This part belongs to the Texas Instruments LM51xx series of gate drivers, optimized for high-voltage power electronics. It complements other variants like the LM5106 and LM5105 by offering specific current and voltage ratings tailored for medium-power half-bridge implementations in modern power supply designs.

Replacement Considerations

LM5107MAX/NOPB offers the same functionality in a different package configuration.
