Infineon Technologies 2EDN7524RXTMA1

Overview

2EDN7524RXTMA1 from Infineon Technologies is a dual-channel, non-inverting, 5 A peak gate driver IC with 4.2 V UVLO, designed for high-frequency switching of MOSFETs and GaN power devices in SMPS topologies. It delivers 17 ns propagation delay, 5 ns slew rate, and 1 ns channel-to-channel delay matching, enabling parallel channel operation in server and telecom power supplies.

For engineers reviewing the 2EDN7524RXTMA1 datasheet, 2EDN7524RXTMA1 pinout, 2EDN7524RXTMA1 application, or 2EDN7524RXTMA1 equivalent, key selection criteria include UVLO threshold (4.2 V), rail-to-rail 5 A output drive strength, TSSOP-8 package compatibility, and LV-TTL/CMOS 3.3 V input logic robustness up to −10 V.

Technical Context

This driver implements independent, rail-to-rail output stages with matched propagation paths-each output sources/sinks 5 A with 0.7 Ω high-side and 0.55 Ω low-side on-resistance. Its −10 V input pin tolerance prevents latch-up under ground bounce, critical when driving pulse transformers or through-hole MOSFETs.

The 4.2 V UVLO ensures immediate shutdown during supply sag, decoupling protection timing from external supervisors. Dual enable inputs (ENA/ENB) provide per-channel control, while direct logic configuration eliminates external inversion circuitry in synchronous rectification or interleaved PFC designs.

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 and thermal stability, operation at 15–18 V is typical in high-current applications-ensuring sufficient headroom above the 4.2 V UVLO while minimizing internal power dissipation in the output stage.

Can the two channels be paralleled for a single 10 A output?

Yes-tight 1 ns channel-to-channel propagation delay matching allows safe parallel connection of OUTA and OUTB. This configuration requires identical external gate resistors (Rg1 = Rg2), shared load, and simultaneous enable (ENA = ENB). No additional balancing components are needed due to matched internal drive strength and timing.

Is the TSSOP-8 package thermally adequate for 5 A continuous output current?

The PG-TSSOP-8 package with exposed thermal pad achieves θ_JA ≈ 60 °C/W under standard 2-layer PCB layout (2 cm² copper pour). At 5 A peak with 50% duty cycle and 100 ns switching transitions, junction temperature rise remains within 45 °C-well below the 150 °C max rating. Thermal derating is only required above 85 °C ambient.

Does the 4.2 V UVLO have hysteresis, and what is its value?

Yes-the 4.2 V UVLO includes 300 mV hysteresis (typ.), meaning the turn-on threshold is 4.2 V and the turn-off threshold is 3.9 V. This prevents oscillatory behavior during slow VDD ramp-up or brown-out recovery and eliminates need for external hysteresis circuitry in auxiliary supply monitoring.
