1EDN8511BXTSA1

Overview

The 1EDN8511BXTSA1 is a single-channel, non-isolated low-side gate driver from Infineon’s EiceDRIVER family. It provides an output source current of 4 A and a sink current of 8 A. The device operates within a supply voltage (Vcc) range of 8 V to 20 V. Key timing parameters include a turn-on propagation delay of 19 ns and a turn-off propagation delay of 19 ns. Undervoltage lockout thresholds are set at 8 V for activation and 7 V for deactivation. The component is qualified for industrial applications and supports operation up to a maximum junction temperature of 150 °C.

Feature Summary

• High peak output current capability with asymmetric sourcing and sinking performance for efficient switching control
• Integrated undervoltage lockout mechanism ensures reliable operation by preventing partial gate drive during insufficient supply conditions
• Fast propagation delay characteristics enable precise timing synchronization in high-frequency power conversion topologies

Applications

• Power factor correction circuits utilizing SiC or GaN devices
• DC-DC converter stages requiring robust low-side switching
• Industrial motor drive systems with standard voltage levels

Procurement Notes

Verify the specific ordering suffix XTSA1 confirms the tape-and-reel packaging format required for automated surface-mount assembly processes. Confirm that the industrial qualification grade meets the thermal and reliability standards of the target application environment. Ensure the non-isolated configuration aligns with the system's ground reference architecture before finalizing procurement specifications.

Selection Notes

Select this component when a single low-side driver with high sink current is required for driving power switches. The 8 A sink capability suits fast-switching devices like SiC MOSFETs. Compare against the 1EDN8550BXTSA1 if different current ratings or package variants are needed. Ensure the input logic levels match the controller output without additional level shifting circuitry.

Part Context

This part belongs to the 1EDN851x series of rugged, cool, and fast gate drivers designed for demanding power electronics applications. It complements other members like the 1EDN751x series which offer lower current capabilities. The series emphasizes compact design and high reliability for modern power density requirements.

Replacement Considerations

The 1EDN8511BXUSA1 is a verified alternative variant within the same product line. Verify pin compatibility and electrical parameter equivalence before substitution.
