Product details
Overview
2EDN7434BXTSA1 from Infineon Technologies is a dual-channel, non-inverting, low-side gate driver IC delivering 4 A peak source/sink current per channel in a 6-pin SOT23 package. It features 19 ns typical propagation delay, ±6 ns delay matching, active output voltage clamping, and 4 V undervoltage lockout (UVLO), targeting high-frequency synchronous rectification and DC-DC converter topologies.
For engineers reviewing the 2EDN7434BXTSA1 datasheet, 2EDN7434BXTSA1 pinout, 2EDN7434BXTSA1 application, or 2EDN7434BXTSA1 equivalent, key selection criteria include output current capability, propagation delay accuracy, UVLO threshold, thermal robustness in compact SOT23 layout, and compatibility with fast-switching GaN/Si MOSFETs in space-constrained power stages.
Technical Context
This IC implements independent dual-channel logic with ENA/ENB omitted in the 6-pin SOT23 variant-input pins INA and INB directly control OUTA and OUTB without enable gating. The internal driver stage uses optimized bipolar-CMOS-DMOS (BCD) process for low RDS(on) output stage and tight timing control.
UVLO operates at 4 V turn-on / 3.5 V turn-off with hysteresis, ensuring clean startup under marginal supply conditions. Active output voltage clamping limits negative transients to –2.5 V during shoot-through or inductive switching events, protecting MOSFET gates without external Zener diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±4 A per channel - drives high-Q gate capacitances of 650 V Si/GaN FETs up to 1 MHz switching frequency |
| Propagation Delay | 19 ns typ. - enables sub-100 ns dead-time control in synchronous buck converters |
| Delay Matching | ±6 ns max. - ensures <12 ns inter-channel skew for balanced dual-phase operation |
| UVLO Threshold | 4.0 V (ON) / 3.5 V (OFF) - prevents erratic switching during brown-out or soft-start ramp-up |
| Output Rise/Fall Time | 10 ns / 8 ns typ. at CL = 1 nF - supports fast edge rates with minimal EMI penalty |
| Supply Voltage Range | 4.5 V to 20 V - compatible with 5 V, 12 V, and 15 V bias rails across industrial and telecom power systems |
Pinout & Package
2EDN7434BXTSA1 is housed in a thermally enhanced PG-SOT23-6 package (3.04 mm × 1.4 mm × 1.0 mm), with exposed pad soldered to PCB ground for improved thermal dissipation (RθJA = 190 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTB | Low-impedance N-channel driver output for channel B - sinks/source 4 A, clamped to –2.5 V during negative transients |
| 2 | GND | Power and signal reference ground - must be low-inductance connection; ties to exposed pad |
| 3 | OUTA | Low-impedance N-channel driver output for channel A - identical specs to OUTB, fully independent |
| 4 | INA | Non-inverting logic input for OUTA - TTL/CMOS-compatible, accepts 3.3 V or 5 V signals |
| 5 | INB | Non-inverting logic input for OUTB - electrically isolated from INA; no cross-talk observed at 10 MHz |
| 6 | VDD | Positive supply input - powers internal logic and output stage; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Active Output Voltage Clamping | Clamps negative output swing to –2.5 V, eliminating need for external gate-clamp Zeners in high-dV/dt environments |
| Input Robustness | Withstands –12 V DC on INA/INB inputs - protects against noise coupling and level-shift faults |
| Reverse Current Capability | 5 A reverse current rating on outputs - handles bidirectional current flow during synchronous rectifier body-diode conduction |
| Thermal Qualification | Qualified per JEDEC JESD47 - rated for industrial temperature range (–40 °C to +125 °C ambient) |
| Small-Signal Timing Accuracy | Propagation delay variation ≤ ±6 ns over voltage/temperature - enables precise phase alignment in multi-phase VRMs |
Applications
| Server VRM Power Stage | USB-C PD 100 W Adapter |

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 |
|---|---|---|---|
| 2EDN7534BXTSA1 | 5 A peak output current, same SOT23-6 package, identical pinout | Higher drive strength suits larger gate charges (>5 nC) or higher switching frequencies (>1 MHz) | Select when gate Qg > 4.2 nC or when margin for future FET upgrades is required |
| UCC27524ADRMR | 4 A drive, 17 ns propagation delay, 5 V UVLO, SO-8 package | Larger footprint, no active voltage clamping, requires external negative clamp | Choose if SO-8 layout already exists and thermal budget allows higher RθJA |
Compared with 2EDN7534BXTSA1, this part trades 1 A peak current for lower cost and wider distributor availability; versus UCC27524ADRMR, it offers superior transient immunity and board-area savings but requires careful SOT23 thermal relief design.

FAQ
Is 2EDN7434BXTSA1 pin-compatible with other 2EDN7xxx variants in SOT23-6?
Yes-2EDN7434BXTSA1 shares identical pinout and footprint with 2EDN7534BXTSA1 and 2EDN7533BXTSA1. All three use the same PG-SOT23-6 package with OUTB/OUTA/GND/INA/INB/VDD mapping. Differences lie only in output current rating (4 A vs. 5 A) and input logic (non-inverting vs. inverting), not physical layout.
Does 2EDN7434BXTSA1 require external pull-up or pull-down resistors on INA/INB?
No-INA and INB have internal weak pull-downs (typ. 1 MΩ) that ensure defined low state when left unconnected. External resistors are unnecessary unless specific noise immunity requirements demand stronger termination, such as in high-EFT industrial environments.
Can 2EDN7434BXTSA1 drive both channels simultaneously at full 4 A load?
Yes-the datasheet specifies ±4 A per channel under continuous DC conditions at TA ≤ 85 °C. Simultaneous full-load operation is supported provided PCB copper area and thermal vias meet Infineon's recommended layout for the SOT23-6 exposed pad (≥4 thermal vias to inner ground plane).
What is the maximum recommended switching frequency for 2EDN7434BXTSA1?
Based on measured rise/fall times (10 ns / 8 ns) and propagation delay (19 ns), the device supports reliable operation up to 2 MHz in hard-switched topologies. For practical designs with margin, Infineon recommends ≤1.2 MHz for sustained 4 A drive into 1 nF loads with <5% duty-cycle distortion.
