L6571AD013TR

Overview

The L6571AD013TR is a high-voltage half-bridge gate driver manufactured by STMicroelectronics, designed for driving external N-channel power MOSFETs and IGBTs. It features a built-in programmable oscillator with frequency set by external components and supports RC input circuitry. The device includes internal dead-time logic to prevent cross-conduction, with a typical duration of 1.25µs. It operates within a supply voltage range of 10V to 16.6V and withstands high-side voltages up to 600V via bootstrap. Key electrical parameters include a minimum operating temperature of -40°C and a maximum of +125°C, with a quiescent current of 25mA.

Feature Summary

• High-voltage half-bridge architecture supporting up to 600V self-bootstrapped operation
• Integrated oscillator with programmable frequency and fixed internal dead time
• Robust dV/dt immunity up to ±50V/ns for noise resistance
• Under-voltage lockout with hysteresis ensures stable startup and shutdown

Applications

• High-voltage motor control systems
• Induction heating power supplies
• Resonant converter topologies
• AC/DC power factor correction stages

Procurement Notes

Verify the specific suffix 'D013' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Confirm end-of-life status or obsolescence notifications prior to finalizing procurement plans. Ensure component authenticity through authorized distribution channels to mitigate counterfeit risks associated with legacy semiconductor parts.

Selection Notes

Select this component when a dedicated half-bridge driver with integrated timing is required for high-side switching applications. The fixed 1.25µs dead time suits standard MOSFET and IGBT switching speeds without requiring external adjustment. Consider the SOIC-8 surface-mount package for compact PCB layouts where thermal dissipation remains within acceptable limits for the intended power density.

Part Context

This part belongs to the L6571 series of high-voltage half-bridge drivers from STMicroelectronics. The series differentiates between versions based on internal dead-time values, such as the L6571A and L6571B. The L6571AD013TR specifically denotes the surface-mount variant in an SOIC-8 package, distinguishing it from through-hole DIP alternatives within the same functional family.

Replacement Considerations

L6571BD (SOIC-8 package, tube) and L6571A (DIP-8 package). Verify pin compatibility and dead-time specifications before substitution.
