1EDN7511BXUSA1

Overview

The Infineon 1EDN7511BXUSA1 is a single-channel low-side gate driver IC designed for switching MOSFETs and GaN devices. It features an output current capability of 4 A source and 8 A sink. The device operates within a supply voltage range of 4.5 V to 20 V and supports both inverting and non-inverting configurations. Key timing parameters include rise and fall times of 6.5 ns and 4.5 ns, respectively, with propagation delays up to 25 ns. It functions reliably across an operating temperature range of -40°C to +150°C.

Feature Summary

• Provides asymmetric drive strength with higher sink current capability for efficient switching control
• Supports flexible logic input compatibility through selectable inverting or non-inverting signal paths
• Engineered for high-temperature operation suitable for demanding power electronics environments

Applications

• Switching control for Silicon Carbide (SiC) and Gallium Nitride (GaN) power devices
• Low-side driver stages in DC-DC converters and synchronous rectification circuits
• Motor drive applications requiring precise gate control for power transistors

Procurement Notes

Verify the specific suffix 'XUSA1' against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure that the selected component matches the required voltage ratings and thermal performance for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a compact low-side driver with high peak sink current is required for fast-switching devices. Consider the SOT-23-6-2 package constraints for PCB layout and thermal dissipation requirements relative to the expected duty cycle and ambient temperature conditions.

Part Context

This part belongs to the 1EDN series of EiceDriver gate drivers from Infineon Technologies. The series focuses on providing robust, non-isolated driving solutions for modern wide-bandgap semiconductors, offering precision timing and high reliability in small form factors.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic replacements may not match the specific 4A/8A asymmetry or the ±5ns delay precision required for GaN applications.
