Infineon Technologies 2EDN7424RXUMA1

Overview

2EDN7424RXUMA1 from Infineon Technologies is a dual-channel, 4 A low-side gate driver IC designed for high-frequency switching of MOSFETs, IGBTs, and GaN power devices in industrial and telecom SMPS. It delivers 19 ns propagation delay, 6 ns slew rate, 2 ns channel-to-channel delay matching, and supports 4.5–20 V VDD with 4.2 V UVLO - enabling precise parallel-channel operation in LLC, PFC, and synchronous rectification topologies.

For engineers reviewing the 2EDN7424RXUMA1 datasheet, 2EDN7424RXUMA1 pinout, 2EDN7424RXUMA1 application, or 2EDN7424RXUMA1 equivalent, key selection criteria include rail-to-rail 4 A sink/source capability per channel, -10 V input robustness, 5 A reverse current tolerance, and TSSOP-8 package compatibility with industry-standard footprints.

Technical Context

The device integrates two independent, matched low-side drivers with LV-TTL/CMOS 3.3 V compatible inputs and +22 V absolute max input voltage tolerance. Each channel features true rail-to-rail output stages delivering 0.84 Ω on-resistance (source) and 0.66 Ω (sink), enabling fast turn-on/turn-off with minimal Miller plateau distortion.

Its UVLO circuit triggers at 4.2 V (with hysteresis) to disable outputs during supply brownout, while ENA/ENB enable pins provide per-channel shutdown control. The internal logic ensures outputs go low on UVLO activation or enable deassertion - critical for safe dead-time management in half-bridge configurations.

Key Specifications

FAQ

What is the maximum allowable VDD voltage for continuous operation?

The absolute maximum VDD rating is 20 V per the datasheet's Absolute Maximum Ratings table. Continuous operation above 18 V is not recommended due to increased quiescent current and reduced thermal margin. Stable operation is guaranteed from 4.5 V to 18 V across the full industrial temperature range (-40 °C to +125 °C).

Can ENA and ENB be tied together for simultaneous channel control?

Yes - ENA and ENB may be shorted and driven by a single microcontroller GPIO or supervisor signal. This configuration maintains independent INA/INB control while ensuring both outputs disable synchronously during fault conditions, preserving system-level safety without additional logic.

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

Yes - Pin 3 (GND) and the exposed thermal pad are internally connected to the die substrate ground. The pad must be soldered to a dedicated PCB ground plane with ≥4 thermal vias (0.3 mm diameter) to maintain junction temperature below 150 °C at 4 A continuous output current.

Does 2EDN7424RXUMA1 support 3.3 V-only logic interfaces without level shifting?

Yes - the inputs are LV-TTL/CMOS compatible with thresholds defined at 0.8 V (low) and 2.0 V (high), fully supporting direct interfacing to 3.3 V microcontrollers and FPGAs. Input voltage tolerance extends to +22 V, allowing safe operation even with transient overshoot on control lines.
