会社ブログについて Infineon 2EDL23 Series 600 V Half-Bridge Gate Driver IC: A Comprehensive Guide to SOI Technology and Selection Criteria (Mingjiada Stock Supply)

In 600 V-class power conversion applications—such as motor drives, general-purpose inverters, and off-line AC-DC power supplies—half-bridge gate drivers play a critical role in reliably “translating” low-voltage control signals into drive pulses for the high-side and low-side power transistors. The 2EDL23x06PJ family, part of Infineon’s EiceDRIVER™ Compact series, has garnered significant attention as a driver IC solution for small- to medium-power half-bridge topologies thanks to its combination of thin-film SOI (Silicon-on-Insulator) technology, integrated bootstrap diodes, and comprehensive protection features. This article provides a comprehensive overview, covering everything from parameters and characteristics to selection and availability.

I. What Is the 2EDL23: A 600 V Half-Bridge Gate Driver IC

The 2EDL23 series is a 600 V half-bridge gate driver IC designed by Infineon using thin-film SOI technology. It is used to drive N-channel MOSFETs or IGBTs in a half-bridge configuration, with a maximum blocking voltage of +600 V. Unlike conventional bulk silicon processes, SOI technology structurally eliminates parasitic thyristors, thereby preventing parasitic latching under all temperature and voltage conditions—which serves as the fundamental guarantee of reliability in high-voltage half-bridge applications.

This series currently consists of two main models tailored for different target transistors:

2EDL23I06PJ: Optimized for IGBTs, with UVLO thresholds of 12.5 V / 11.6 V;

2EDL23N06PJ: Optimized for MOSFETs, with UVLO thresholds of 9.1 V / 8.3 V.

Both models use the DSO-14 package and are pin-compatible; selection is primarily based on the gate requirements of the target power device and the system’s UVLO window.

II. Key Features Breakdown: Why the 2EDL23 Is Suitable for 600 V Half-Bridge Circuits

1. Integrated ultra-fast bootstrap diode eliminates the need for external components

The 2EDL23 integrates an ultra-fast, low RDS(ON) bootstrap diode, with a floating channel specifically designed for bootstrap charging. For high-side drive in half-bridge configurations, the switching speed and reverse recovery characteristics of the bootstrap diode directly impact the establishment efficiency and power loss of the high-side power supply. The integrated solution not only saves PCB area but also reduces the uncertainty in parasitic parameters caused by external components.

2. Output Drive Capability and Propagation Delay

The output pull-up/pull-down current capability is +1.8 A / −2.5 A (some documentation specifies 2.3 A / 2.8 A for the N version, depending on test conditions and differences among target devices). Typical propagation delay is only 10 ns, with a maximum of 60 ns; delay matching between channels is also kept within 60 ns. For half-bridge topologies requiring precise dead-time control or high-frequency switching, smaller delay mismatch translates to more controllable timing margins.

3. Negative Transient Tolerance Enabled by SOI Technology

In half-bridge topologies, switching commutation generates negative transient spikes at the VS node. The 2EDL23’s SOI structure can withstand negative transient voltages as low as −100 V (pulse width ≤ 300 ns), far exceeding the typical tolerance levels of conventional junction-isolated devices. Additionally, its dV/dt immunity of ±50 V/ns helps suppress false triggering in fast-switching scenarios.

4. Protection and Logic Interface

The device integrates overcurrent protection, enable functionality, fault reporting, interlock, and dead-time control, and features independent, asymmetric under-voltage lockout (UVLO) thresholds for the high-side and low-side. The input logic is compatible with 3.3 V, 5 V, and 15 V levels, allowing direct interfacing with common MCUs or DSPs without the need for additional level shifting. The offline gate clamping feature prevents parasitic conduction caused by floating gates when VDD is not powered, further enhancing safety during system power-up and power-down sequences.

III. 2EDL23I06PJ vs. 2EDL23N06PJ: How to Choose

Comparison Items: 2EDL23I06PJ 2EDL23N06PJ

Target Transistor: IGBT MOSFET (e.g., CoolMOS™)

Typical UVLO Threshold: 12.5 V / 11.6 V 9.1 V / 8.3 V

Output Current (Nominal): 2.3 A 2.3 A / 2.8 A

Package: DSO-14 DSO-14

Selection Logic: The gate threshold and Miller platform voltage of IGBTs are typically higher than those of MOSFETs; therefore, the I version features a higher UVLO threshold to ensure that no drive signal is output until VDD has stabilized sufficiently to allow the IGBT to turn on reliably. The lower UVLO window of the N version is designed to match the gate requirements of low-voltage logic MOSFETs or CoolMOS™. When selecting a device, drive losses should also be calculated based on the target device’s Qg, switching frequency, and thermal conditions.

IV. Typical Application Scenarios

The 2EDL23 series is positioned to cover multiple segments of 600 V-class half-bridge and full-bridge conversion applications:

Motor drives and general-purpose inverters: Half-bridge power stages in variable-frequency drives for fans, pumps, compressors, etc.;

Home Appliances and Refrigeration Compressors: Inverter circuits for white goods such as air conditioners and refrigerators have high requirements for integration and reliability; the 2EDL23’s small package and built-in protection help reduce board space;

Offline AC-DC Power Supplies: Half-bridge and full-bridge converters in telecommunications and lighting power supplies; the 600 V blocking voltage and negative transient immunity directly address the operating conditions of offline bus systems;

Industrial and Consumer Power Stages: This series is also commonly found in gate driver circuits for induction heating, UPS, and solar system solutions.
