Infineon Technologies 6EDL04I065PTXUMA1

Overview

6EDL04I065PTXUMA1 from Infineon is a 650 V three-phase gate driver IC for IGBTs in industrial motor inverters, featuring integrated bootstrap diodes, ±0.165 A/–0.375 A peak output current, 530 ns/490 ns typical turn-on/turn-off times, and programmable over-current fault clear delay via RCIN. It enables robust high-side drive in 3-phase bridge topologies for refrigeration compressors and power tools.

For engineers reviewing the 6EDL04I065PTXUMA1 datasheet, 6EDL04I065PTXUMA1 pinout, 6EDL04I065PTXUMA1 application, or 6EDL04I065PTXUMA1 equivalent, key selection criteria include SOI-based transient immunity (–50 V negative transients), CMOS/LSTTL-compatible positive-logic inputs, interlocked phase control to prevent shoot-through, and integrated UVLO with 11.7 V/9.8 V thresholds.

Technical Context

This device implements six independent gate drivers-three high-side (HO1–HO3) and three low-side (LO1–LO3)-each with dedicated level-shifting, dead-time insertion (~310 ns), and input noise filtering. Its SOI process eliminates latch-up risk and supports operation up to 670 V offset voltage.

The functional architecture includes separate UVLO monitoring per supply domain (VCC, VBx), analog over-current detection via ITRIP pin with external resistor programming, open-drain FAULT signaling, and EN-controlled global shutdown. Bootstrap diodes (VBx–VCC) are monolithically integrated with low R_DS(ON) and ultra-fast recovery.

FAQ

What logic polarity does 6EDL04I065PTXUMA1 use for HIN/LIN inputs?

6EDL04I065PTXUMA1 uses positive logic: HINx and LINx inputs are active-high. A logic HIGH enables the corresponding HOx or LOx output; LOW disables it. This matches standard microcontroller GPIO behavior without inversion logic, and is confirmed in Table 1 of the datasheet for the "6EDL04I065PT" variant.

How is over-current protection implemented and reset?

OCP is implemented via the ITRIP pin, which monitors an external current-sense voltage. When exceeded, the FAULT pin goes low and all outputs shut down. Recovery requires the ITRIP condition to clear *and* the RCIN pin voltage to discharge below its internal threshold-achieved by the 2.8 µA internal current source charging an external capacitor, setting a precise fault-hold time.

Can the integrated bootstrap diodes replace external diodes in all cases?

Yes-the monolithic bootstrap diodes (VCC→VB1/VB2/VB3) are rated for continuous operation in typical 3-phase inverter duty cycles (≤50% high-side conduction). They eliminate the need for external diodes in most home appliance and power tool applications, provided layout minimizes VB node loop inductance and thermal dissipation remains within SOA limits.

What is the purpose of the EN pin beyond basic enable/disable?

EN serves as a hardware safety interlock: pulling EN low forces all six outputs low regardless of input states. Its internal 75 kΩ pull-down ensures fail-safe shutdown during open-circuit faults. Optionally, an external NTC thermistor can extend EN functionality to over-temperature protection by connecting between EN and VCC, leveraging the pin's Schmitt-trigger thresholds (2.1 V/1.3 V).
