Infineon Technologies 2EDN7434FXTMA1

Overview

2EDN7434FXTMA1 from Infineon Technologies is a dual-channel, non-inverting, low-side gate driver IC delivering ±4 A peak output current, 19 ns typical propagation delay, and ±6/–4 ns propagation delay accuracy. It operates from 4.5 V to 20 V supply voltage with 4 V UVLO threshold and is housed in an 8-pin DSO package. It drives N-channel MOSFETs in synchronous rectification stages of DC-DC converters.

For engineers reviewing the 2EDN7434FXTMA1 datasheet, 2EDN7434FXTMA1 pinout, 2EDN7434FXTMA1 application, or 2EDN7434FXTMA1 equivalent, key selection criteria include output current capability (4 A), timing precision (19 ns / ±6 ns), UVLO level (4 V), active output clamping, and industrial qualification per JEDEC standards.

Technical Context

This IC integrates two independent low-side drivers with matched propagation delays and tightly controlled start-up (1.8 µs) and shut-down (500 ns) times. Its logic accepts direct (non-inverting) input signals on INA/INB and enables channel-by-channel control via ENA/ENB, with both outputs forced low during UVLO or enable deactivation.

The device features active output voltage clamping to protect against negative transients, supports –12 V input robustness and 5 A reverse current tolerance, and maintains stable operation across –40 °C to +125 °C ambient temperature range with thermal pad-connected GND for enhanced power dissipation.

Key Specifications

Pinout & Package

2EDN7434FXTMA1 is packaged in PG-DSO-8 (8-pin exposed-pad SOIC), with GND connected to the thermal pad for improved thermal performance and noise immunity. Pin 3 is the common ground reference for both driver channels and logic inputs.

FAQ

What is the maximum recommended VDD 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 long-term reliability at full temperature range (–40 °C to +125 °C), operation above 18 V is not advised without derating the output current or verifying thermal margin with layout-specific simulation.

Can ENA and ENB be tied together and driven by a single microcontroller GPIO?

Yes-ENA and ENB may be paralleled and driven by one GPIO if simultaneous channel enable/disable is acceptable. However, doing so eliminates independent channel control; for asymmetric timing or fault isolation, separate enable lines are required per the pin configuration table.

Is the thermal pad on the DSO-8 package electrically connected to GND internally?

Yes-the exposed thermal pad on the PG-DSO-8 package (2EDN7434FXTMA1) is internally connected to GND and must be soldered to a PCB copper pour tied to the system ground plane to ensure proper thermal dissipation and noise immunity.

Does the 4 V UVLO option support operation with 5 V logic-level microcontrollers?

Yes-the 4 V UVLO threshold allows reliable startup from 5 V rails, and the device's input pins tolerate –12 V to +20 V, making it compatible with standard 3.3 V or 5 V MCU GPIOs without level-shifting circuitry.
