E-L6574D013TR

Overview

The L6574D013TR is a half-bridge MOSFET gate driver designed for CFL and TL ballast applications, manufactured using BCD OFF LINE technology to support voltage ratings exceeding 600V. It integrates two drivers with output currents of 250mA source and 450mA sink. The device operates within a supply voltage range of 10V to 16.6V and features switching times of 80ns rise and 40ns fall. It includes an integrated bootstrap diode, under-voltage lockout, and a CMOS shutdown input. The component is housed in a SOIC-16 package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrated bootstrap section eliminates the need for external bootstrap diodes and Zener clamping on Vs.

Applications

• CFL ballast systems
• TL ballast systems

Procurement Notes

Verify the specific suffix '013' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required operating temperature range and voltage ratings for the intended ballast application before procurement.

Selection Notes

Select this component for high-performance ballast designs requiring low external component count due to the integrated bootstrap diode. Consider the dV/dt immunity and closed-loop control capabilities via the internal op amp when designing circuits for precise lamp current regulation.
