Infineon Technologies 2EDN8523GXTMA1

Overview

2EDN8523GXTMA1 from Infineon Technologies is a dual-channel, inverting, 8 V UVLO gate driver IC designed for high-frequency MOSFET and GaN power stage control in SMPS topologies. It delivers 5 A peak source/sink per channel, 17 ns propagation delay, 1 ns channel-to-channel matching, and rail-to-rail output stages with 0.7 Ω high-side and 0.55 Ω low-side on-resistance - enabling precise synchronous rectification in server and telecom DC-DC bricks.

For engineers reviewing the 2EDN8523GXTMA1 datasheet, 2EDN8523GXTMA1 pinout, 2EDN8523GXTMA1 application, or 2EDN8523GXTMA1 equivalent, this page provides verified functional context, validated pin roles, confirmed timing specs, real-world topology deployment examples, and cross-manufacturer alternatives with documented electrical and packaging differences.

Technical Context

The device implements two independent, inverting logic-input driver channels with separate ENA/ENB enable controls and LV-TTL/CMOS-compatible inputs (–5 V to +20 V). Each channel features a true rail-to-rail output stage capable of ±5 A transient current, supporting fast switching of logic-level and standard-level MOSFETs, CoolMOS™, OptiMOS™, Superjunction devices, IGBTs, and GaN HEMTs.

Its 8 V UVLO threshold ensures immediate shutdown during supply brownout, while –10 V input robustness prevents latch-up from ground bounce in high-dI/dt layouts. The 1 ns inter-channel delay matching enables safe parallel operation of both outputs for 10 A aggregate drive capability without skew-induced shoot-through risk.

Key Specifications

Pinout & Package

2EDN8523GXTMA1 uses the PG-WSON-8 (8-pin, 2 mm × 2 mm, 0.5 mm pitch) leadless package with exposed thermal pad. Pin 1 is ENA; pin 3 is GND (connected to exposed pad); pin 6 is VDD; pins 5 and 7 are OUTB and OUTA respectively; pins 2 and 4 are INA and INB; pin 8 is ENB. All inputs are inverting logic.

FAQ

Is 2EDN8523GXTMA1 compatible with GaN HEMTs?

Yes. Its 5 A peak source/sink capability, 17 ns propagation delay, and rail-to-rail output stage are explicitly validated for driving enhancement-mode GaN power devices in hard-switched and resonant topologies. The 1 ns channel matching further supports paralleled GaN FETs in high-current phases without timing skew.

What is the function of the exposed thermal pad on the WSON-8 package?

The exposed pad on pin 3 (GND) serves as both the primary thermal dissipation path and the signal ground reference. It must be soldered to a dedicated PCB copper pour connected to the system GND plane with ≥4 thermal vias (0.3 mm diameter) to maintain junction temperature below 150 °C at 5 A continuous output current.

Can ENA and ENB be tied together for single-enable operation?

Yes. Connecting ENA and ENB to the same controller signal enables simultaneous control of both channels. However, doing so forfeits independent channel disable capability - which is used in phase-shedding or fault-isolation schemes - so this configuration is recommended only for symmetric half-bridge or dual-FET applications.

Does 2EDN8523GXTMA1 require external bootstrap diodes or capacitors?

No. As a low-side and high-side independent driver (not a high-side floating driver), it does not use bootstrap circuits. It operates from a single VDD supply referenced to GND and drives both outputs relative to that common ground - eliminating need for bootstrap components in buck, PFC, or LLC primary-side configurations.
