Product details
Overview
2EDN7534BXTSA1 from Infineon Technologies is a dual-channel, non-inverting, low-side gate driver IC delivering ±5 A peak output current per channel in a 6-pin SOT23 package. It features 19 ns typical propagation delay, ±4 ns propagation delay accuracy, and active output voltage clamping for MOSFET/IGBT switching in high-frequency power converters. Used in synchronous rectification stages of DC-DC converters.
For engineers reviewing the 2EDN7534BXTSA1 datasheet, 2EDN7534BXTSA1 pinout, 2EDN7534BXTSA1 application, or 2EDN7534BXTSA1 equivalent, key selection criteria include UVLO threshold (4 V), logic configuration (direct), thermal robustness (−40 °C to +125 °C), and compatibility with fast-switching GaN and SiC power stages.
Technical Context
The 2EDN7534BXTSA1 implements independent dual-channel control with separate enable (ENA/ENB) and input (INA/INB) pins, supporting asynchronous operation and channel disable without affecting the other. Its internal logic ensures both outputs go low during UVLO activation or when either enable pin is driven low.
It integrates active output voltage clamping to limit negative transients at OUTA/OUTB during fast turn-off, enhancing reliability in high-dV/dt environments. The 4 V UVLO threshold provides early supply monitoring while maintaining stable operation down to 4.5 V nominal VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±5 A per channel - drives high-Q gate capacitances of GaN HEMTs and SiC MOSFETs at >1 MHz switching frequencies. |
| Propagation Delay | 19 ns typ. - enables precise timing alignment between channels for interleaved topologies. |
| Delay Matching | ±4 ns max - minimizes skew-induced shoot-through risk in dual-phase synchronous buck designs. |
| UVLO Threshold | 4 V (ON), 3.5 V (OFF) - prevents erratic operation during brown-out while allowing startup from low-voltage rails. |
| VDD Operating Range | 4.5 V to 20 V - supports 5 V, 12 V, and 15 V bias supplies without external regulation. |
| Output Rise/Fall Time | 10 ns typ. (1 nF load) - reduces switching losses and EMI in hard-switched converters. |
| Input Robustness | −12 V DC tolerant - withstands negative transient coupling on INA/INB in noisy industrial environments. |
Pinout & Package
2EDN7534BXTSA1 is housed in a PG-SOT23-6 package (3.0 mm × 1.7 mm, 0.95 mm height), optimized for space-constrained DC-DC modules and POL regulators. Thermal pad is not present; GND is connected via Pin 2 only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTB | Low-impedance N-channel output stage - sinks/source up to 5 A to drive gate of low-side MOSFET B. |
| 2 | GND | Reference ground for logic and power stages - must be low-inductance connection to minimize ground bounce. |
| 3 | OUTA | Low-impedance N-channel output stage - independently controlled, matched timing with OUTB. |
| 4 | INA | Non-inverting logic input for OUTA - high = OUTA high; low = OUTA low (when ENA high or floating). |
| 5 | INB | Non-inverting logic input for OUTB - supports independent PWM or phase-shifted control of second channel. |
| 6 | VDD | Positive supply input - powers internal logic and output drivers; bypass capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Active Output Voltage Clamping | Clamps OUTA/OUTB to −2.5 V during negative dV/dt events - eliminates need for external clamping diodes in high-speed layouts. |
| Independent Channel Enable | ENA/ENB pins omitted in SOT23-6 variant - direct control via INA/INB only, simplifying PCB routing for single-enable systems. |
| Tight Timing Accuracy | ±4 ns propagation delay matching between channels - enables sub-10 ns dead-time control in critical synchronous rectifiers. |
| High Noise Immunity | −12 V input tolerance and 5 A reverse current robustness - survives ESD and inductive kickback without latch-up. |
| Industrial Qualification | JEDEC JESD47 qualified - rated for −40 °C to +125 °C ambient, suitable for uncooled telecom and server PSU designs. |

| Server VRM Power Stage | USB-C PD Fast Charger |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27524ADR | 4 A peak output, 17 ns propagation delay, no active clamping, 5 V UVLO only | Lacks negative transient protection; requires external clamp diodes in GaN designs | Prefer where cost sensitivity outweighs robustness needs and VDD ≥ 6 V is guaranteed |
| LM5113MMX/NOPB | 5 A peak, 25 ns propagation delay, 8 V UVLO, no IN/OUT pin separation in SOT23 | Higher UVLO threshold limits use in low-VDD start-up; larger timing skew impacts multi-phase sync | Acceptable for 12 V–24 V industrial SMPS where timing margin >10 ns is available |
Compared with UCC27524ADR and LM5113MMX/NOPB, 2EDN7534BXTSA1 delivers tighter delay matching (±4 ns vs. ±8 ns), integrated clamping, and lower UVLO (4 V), making it superior for high-efficiency, high-density GaN-based DC-DC converters requiring robust transient immunity.

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 125 °C ambient, Infineon specifies derating above 17 V under full load; sustained operation at 20 V is permitted only with adequate PCB copper area and ≤85 °C case temperature.
Does 2EDN7534BXTSA1 support independent enable control per channel?
No - the SOT23-6 variant (2EDN7534BXTSA1) omits ENA and ENB pins. Channel enable is implicit: OUTA follows INA and OUTB follows INB whenever VDD is above UVLO threshold. To disable a channel, drive its input low.
Can this driver safely interface directly with 3.3 V logic microcontrollers?
Yes - the inputs are CMOS-compatible with VIH = 2.0 V min and VIL = 0.8 V max at VDD = 5 V. A 3.3 V MCU GPIO meets these thresholds with margin; no level-shifting is required. Input hysteresis is 0.3 V, improving noise rejection.
Is there an exposed thermal pad on the SOT23-6 package?
No - unlike the DSO-8, TSSOP-8, and WSON-8 variants, the PG-SOT23-6 package (used for 2EDN7534BXTSA1) has no exposed thermal pad. Thermal dissipation relies solely on the leadframe and PCB copper; junction-to-ambient θJA is 210 K/W in standard JEDEC 2S2P layout.
