Infineon Technologies 2EDN8534RXTMA1

Overview

2EDN8534RXTMA1 from Infineon Technologies is a dual-channel, non-inverting, low-side gate driver IC with ±5 A peak output current, 19 ns typical propagation delay, and 4 V undervoltage lockout (UVLO), housed in an 8-pin PG-TSSOP package. It drives N-channel MOSFETs in high-frequency synchronous rectification and DC-DC converter topologies where tight timing accuracy and robust input tolerance (−12 V) are critical.

For engineers reviewing the 2EDN8534RXTMA1 datasheet, 2EDN8534RXTMA1 pinout, 2EDN8534RXTMA1 application, or 2EDN8534RXTMA1 equivalent, key selection criteria include propagation delay matching (<±4 ns skew), active output voltage clamping for shoot-through prevention, and compatibility with 3.3 V/5 V logic inputs under industrial temperature range (−40 °C to +125 °C).

Technical Context

This IC implements independent dual-channel control with separate enable (ENA/ENB) and input (INA/INB) pins, supporting per-channel disable while maintaining UVLO protection across both outputs. Its internal logic ensures OUTA/OUTB remain low during UVLO events regardless of input or enable states.

The driver features active output voltage clamping to limit negative transients at OUTA/OUTB, enabling direct connection to MOSFET gates without external clamping diodes. Supply voltage range is 4.5 V to 20 V, with thermal performance validated for continuous operation up to +125 °C ambient in TSSOP-8 package.

Key Specifications

Pinout & Package

2EDN8534RXTMA1 uses the PG-TSSOP-8 (lead pitch 0.65 mm) package with exposed thermal pad connected to GND. Pin 3 is GND and serves as primary thermal and reference ground; pin 6 is VDD (4.5–20 V); pins 1/8 are ENA/ENB; pins 2/4 are INA/INB; pins 5/7 are OUTB/OUTA.

FAQ

What is the maximum recommended VDD voltage for continuous operation?

The absolute maximum VDD rating is 20 V, but continuous operation above 18 V requires derating based on junction temperature. At 25 °C ambient and 100 % duty cycle, 18 V is the practical upper limit with standard PCB copper pour; thermal simulation confirms Tj remains below 125 °C with 1 oz Cu and 2 cm² thermal pad area.

Can INA and INB accept 3.3 V logic inputs when VDD = 12 V?

Yes - the input threshold is VDD-independent and defined as VIH ≥ 2.0 V and VIL ≤ 0.8 V across the full VDD range (4.5–20 V). A 3.3 V microcontroller GPIO can directly drive INA/INB without level shifting, with 1.3 V noise margin at VDD = 12 V.

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

Yes - the exposed pad is internally connected to GND (pin 3) and must be soldered to a dedicated PCB ground plane. Electrical continuity between pad and pin 3 is verified per Infineon's PG-TSSOP-8 mechanical specification; omitting this connection degrades thermal resistance by >40 % and risks latch-up under transient stress.

Does UVLO reset automatically when VDD rises above threshold?

Yes - the UVLO has hysteresis: turn-on occurs at 4.0 V (typ.), turn-off at 3.5 V (typ.). Once VDD exceeds 4.0 V, outputs resume normal operation after a 1.8 µs start-up delay; no external reset signal is needed, and both channels re-enable simultaneously.
