Infineon Technologies 6EDL04N065PTXUMA1

Overview

6EDL04N065PTXUMA1 from Infineon is a 650 V three-phase gate driver IC for MOSFET-based motor inverters, featuring integrated bootstrap diodes, over-current protection (OCP), enable control, and open-drain fault reporting. It delivers ±0.165 A / −0.375 A peak output current, supports 3.3 V–5 V logic inputs (positive logic), and provides 310 ns interlocking dead time to prevent shoot-through in bridge legs.

For engineers reviewing the 6EDL04N065PTXUMA1 datasheet, 6EDL04N065PTXUMA1 pinout, 6EDL04N065PTXUMA1 application, or 6EDL04N065PTXUMA1 equivalent, key selection criteria include its SOI-based transient ruggedness (−50 V negative transient immunity), externally programmable fault-clear delay via RCIN, and integrated high-side bootstrap diodes eliminating external diode placement in compact inverter designs.

Technical Context

The device implements six independent gate drivers-three high-side (HO1–HO3) and three low-side (LO1–LO3)-each with dedicated level-shifting, UVLO detection (9.0 V / 8.1 V thresholds), and noise-filtered CMOS/LSTTL-compatible inputs. Its SOI process eliminates parasitic latch-up across temperature and voltage extremes.

Over-current protection is analog-based: ITRIP pin accepts a resistor-defined threshold voltage, triggering latched shutdown and FAULT assertion; RCIN sets fault-clear delay using an internal 2.8 µA current source. EN enables/disables all outputs with Schmitt-trigger hysteresis (2.1 V/1.3 V) and 780 ns propagation delay.

FAQ

What logic polarity does 6EDL04N065PTXUMA1 support?

This part uses positive logic for both HINx and LINx inputs: a HIGH signal (≥2.0 V) enables the corresponding HOx or LOx output, while LOW disables it. Internal 5 kΩ pull-down resistors ensure safe default OFF state during power-up or open-circuit conditions, eliminating need for external biasing.

How is over-current protection configured and reset?

OCP is set by connecting a resistor between ITRIP (Pin 9) and VSS to define the trip voltage threshold (e.g., 10 kΩ yields ~1.2 V). When exceeded, FAULT asserts low and all outputs shut down. Reset occurs after the fault condition clears and the RCIN (Pin 11) capacitor discharges below threshold, using an internal 2.8 µA current source to charge the external RC network.

Can 6EDL04N065PTXUMA1 drive IGBTs instead of MOSFETs?

No - this variant is specifically optimized for MOSFETs, with UVLO thresholds of 9.0 V (turn-on) and 8.1 V (turn-off), lower than the 11.7 V/9.8 V thresholds used in the IGBT-optimized 6EDL04I065NT/PT variants. Using it with IGBTs risks insufficient gate drive voltage during brown-out conditions, leading to increased conduction losses or thermal runaway.

What is the purpose of the COM pin, and how should it be routed?

COM serves as the dedicated return path for all three low-side gate driver outputs (LO1–LO3); it must be connected directly to the source terminals of the low-side power switches via a low-inductance, wide copper pour. Separating COM from VSS prevents coupling of high di/dt switching noise into logic ground, preserving input noise immunity and preventing false FAULT assertions.
