Infineon Technologies 2EDN7424RXTMA1

Overview

2EDN7424RXTMA1 from Infineon Technologies is a dual-channel 4 A low-side gate driver IC designed for high-frequency switching of MOSFETs, GaN devices, and IGBTs in industrial and telecom SMPS. It delivers 6 ns slew rate, 19 ns propagation delay, ±1 ns channel-to-channel matching, 4.2 V UVLO, and rail-to-rail 4 A sink/source capability per channel.

For engineers reviewing the 2EDN7424RXTMA1 datasheet, 2EDN7424RXTMA1 pinout, 2EDN7424RXTMA1 application, or 2EDN7424RXTMA1 equivalent, key selection criteria include propagation delay precision, reverse current robustness (5 A), LV-TTL/CMOS 3.3 V input compatibility, and TSSOP-8 package thermal performance in high-density power stages.

Technical Context

The device implements two independent, fully buffered low-side driver channels with matched internal timing paths-enabling parallel operation without external skew compensation. Each channel features dedicated enable (ENA/ENB) and input (INA/INB) pins with LV-TTL logic thresholds and +22 V absolute max input voltage rating.

Its UVLO circuit triggers at 4.2 V (typ.) with hysteresis, ensuring safe gate drive disable during brown-out conditions independent of system supervisors. The output stage uses true rail-to-rail bipolar architecture, achieving 0.84 Ω on-resistance sourcing to VDD and 0.66 Ω sinking to GND.

Key Specifications

Pinout & Package

FAQ

What is the maximum recommended VDD supply voltage for continuous operation?

The absolute maximum VDD rating is 20 V, but the recommended operating range is 4.5 V to 20 V. For reliable long-term operation with minimal thermal stress, maintain VDD between 12 V and 18 V when driving high-Qg devices at >1 MHz. Exceeding 20 V risks permanent damage to internal regulators and output transistors.

Can ENA and ENB be tied together for single-enable control of both channels?

Yes-ENA and ENB may be connected to a common enable signal without adverse effects. The internal logic ensures both outputs go low simultaneously upon enable deassertion, preserving channel synchronization. This configuration is validated in Infineon's AN2017-05 application note for interleaved PFC designs.

Is the exposed thermal pad on the TSSOP-8 package electrically connected internally?

Yes-the exposed pad is internally connected to GND and must be soldered to a PCB GND plane with ≥4 thermal vias (0.3 mm diameter) for optimal thermal resistance (θ_JA = 65 °C/W typical). Leaving it floating degrades thermal performance and increases junction temperature by up to 25 °C at full load.

Does the 2EDN7424RXTMA1 support 3.3 V microcontroller GPIOs directly?

Yes-its inputs are LV-TTL compatible with guaranteed recognition of logic high at ≥2.0 V and logic low at ≤0.8 V, making it fully interoperable with 3.3 V MCU GPIOs without level shifters. Input hysteresis of 0.5 V further enhances noise immunity in noisy power environments.
