L6574D013TR

Overview

The L6574D013TR is a half-bridge gate driver manufactured by STMicroelectronics, designed for CFL and TL ballast applications. It operates within a supply voltage range of 10 V to 16.6 V and delivers an output current of 450 mA. The device features rise and fall times of 80 ns and 40 ns respectively, with a quiescent current of 25 mA. It supports an operating temperature range from -40 °C to +125 °C and is housed in a SOIC-16 surface-mount package.

Feature Summary

• Integrated bootstrap section eliminates the need for external bootstrap diodes and Zener clamping on Vs.
• High dV/dt immunity of ±50 V/ns ensures reliable operation under full temperature ranges with capacitive loads.
• Built-in preheat and frequency shifting timing sections facilitate proper lamp ignition and control.

Applications

• Compact Fluorescent Lamp (CFL) ballasts
• Tubular Fluorescent Lamp (TL) ballasts
• Half-bridge power converter topologies

Procurement Notes

Verify the specific suffix D013TR against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage limits and thermal requirements before integration. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics for your specific design implementation.

Selection Notes

Select this component when designing high-voltage ballast circuits requiring integrated bootstrap functionality to reduce external component count. It is suitable for applications needing precise preheat timing and closed-loop current control via the internal operational amplifier. Consider the SOIC-16 package constraints and thermal dissipation capabilities during layout planning.
