Infineon Technologies 2EDS9265HXUMA1

Overview

2EDS9265HXUMA1 from Infineon Technologies is a dual-channel, reinforced isolated MOSFET gate driver IC with coreless transformer isolation, delivering 4 A source / 8 A sink peak output current per channel, 37 ns typical propagation delay, ±3 ns channel-to-channel mismatch, and >150 V/ns CMTI - designed for high-reliability half-bridge switching in industrial SMPS and EV charging systems using CoolMOS™ or CoolGaN™ power devices.

For engineers reviewing the 2EDS9265HXUMA1 datasheet, 2EDS9265HXUMA1 pinout, 2EDS9265HXUMA1 application, or 2EDS9265HXUMA1 equivalent, this part supports fast-switching topologies requiring reinforced isolation (VIOTM = 8 kVpk), precise timing stability across –40°C to +150°C, and independent high-side/low-side drive capability in WB PG-DSO-16-30 package.

Technical Context

The 2EDS9265HXUMA1 implements two fully galvanically isolated gate driver channels using coreless transformer (CT) technology, enabling functional separation of input logic (3.3 V CMOS/TTL) and output power stages (4.5–20 V). Its internal UVLO monitors both input-side (8 V threshold) and output-side supplies, triggering safety lock-down on fault detection.

Timing accuracy is maintained via matched signal paths: propagation delay variance is limited to +7/–6 ns, and channel-to-channel skew is tightly controlled at ±3 ns. The device supports PWM inputs with 18 ns noise filtering and withstands common-mode transients up to 150 V/ns without false triggering - critical for high-dV/dt environments like LLC resonant converters.

FAQ

What is the maximum recommended switching frequency for 2EDS9265HXUMA1?

The 2EDS9265HXUMA1 supports PWM operation up to 10 MHz, as confirmed by its 37 ns typical propagation delay and +7/–6 ns delay variance. This allows stable use in hard-switched topologies up to 2 MHz and resonant converters (e.g., LLC) operating above 1 MHz, provided PCB layout minimizes parasitic inductance on gate loops.

Does 2EDS9265HXUMA1 require external bootstrap diodes or capacitors?

No - the 2EDS9265HXUMA1 itself does not integrate bootstrap circuitry. However, when used in high-side configurations, external bootstrap components (diode + capacitor) are required on the VDDA rail to generate the floating supply. The IC's GNDA pin serves as the local return for that bootstrap network, and layout must isolate it from power ground.

Can the DISABLE pin be left unconnected?

No - the DISABLE pin has an internal pull-down resistor, but leaving it floating risks unintended activation due to noise coupling. It must be actively driven low (to GNDI) for normal operation or pulled high (to VDDI) to disable both outputs. A 10 kΩ pull-down is recommended if unused in the system.

How is reinforced isolation verified for 2EDS9265HXUMA1?

Reinforced isolation is verified per DIN V VDE V 0884-10 (2006-12) with 8 kVpk transient isolation voltage and 10 kVpk surge testing (25 positive/negative pulses). It is also certified to UL1577 (5700 VRMS) and EN/IEC 62368-1, with test reports available from Infineon upon request - no external retesting is needed for end-equipment compliance.
