Product details
Overview
2EDN7433BXTSA1 from Infineon Technologies is a dual-channel, low-side gate driver IC with 4 A peak source/sink output current, ±5 ns propagation delay accuracy, and 19 ns typical propagation delay. It features active output voltage clamping, 4 V undervoltage lockout (UVLO), and operates from 4.5 V to 20 V supply. Designed for synchronous rectification stages in DC-DC converters, it enables fast, robust MOSFET switching with precise timing control.
For engineers reviewing the 2EDN7433BXTSA1 datasheet, 2EDN7433BXTSA1 pinout, 2EDN7433BXTSA1 application, or 2EDN7433BXTSA1 equivalent, key selection criteria include UVLO threshold matching, logic configuration (inverting input), SOT23-6 footprint compatibility, and gate drive strength for high-frequency buck or LLC secondary-side FETs.
Technical Context
This device implements two independent, inverting-input low-side drivers with dedicated enable pins (ENA/ENB) and shared VDD/GND. Each channel delivers 4 A peak current with <19 ns propagation delay and tight ±5 ns channel-to-channel matching, enabling precise dead-time control in synchronous topologies.
The integrated active output voltage clamp limits negative transients to –2.5 V during fast turn-off, protecting MOSFET gates without external components. Its 4 V UVLO ensures reliable startup only when VDD exceeds 4.0 V, preventing erratic operation during brown-out conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±4 A - sufficient to drive high-Qg MOSFETs at >1 MHz switching frequencies with minimal rise/fall time degradation |
| Propagation Delay | 19 ns typ. - enables sub-50 ns minimum on-time capability in high-frequency DC-DC controllers |
| Delay Accuracy | ±5 ns - ensures consistent channel timing for accurate synchronous rectifier control and reduced shoot-through risk |
| UVLO Threshold | 4.0 V (ON), 3.5 V (OFF) - provides clean power-up sequencing and brown-out immunity for industrial 5 V rail systems |
| Supply Voltage Range | 4.5 V to 20 V - supports direct connection to 5 V, 12 V, or 15 V bias rails without LDO regulation |
| Output Clamp Voltage | –2.5 V - suppresses negative gate ringing below MOSFET VGS rating, eliminating need for external clamping diodes |
| Start-up Time | 1.8 µs - allows rapid response to enable signals in burst-mode or adaptive control schemes |
Pinout & Package
2EDN7433BXTSA1 is housed in a PG-SOT23-6 package (3.0 mm × 1.7 mm, 0.95 mm height), optimized for space-constrained synchronous rectifier designs. The exposed pad is not present in this variant; all six terminals are wire-bonded signal leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTB | Low-side driver output for channel B - directly connects to source of synchronous rectifier MOSFET |
| 2 | GND | Power and signal reference ground - must be low-inductance connection to PCB ground plane |
| 3 | OUTA | Low-side driver output for channel A - drives second synchronous rectifier FET in dual-phase or interleaved topologies |
| 4 | INA | Inverting logic input for channel A - high input yields low output; compatible with standard CMOS/TTL logic levels |
| 5 | INB | Inverting logic input for channel B - independent control path enables asymmetric duty-cycle or phase-shifted operation |
| 6 | VDD | Positive supply input - powers internal logic and output stage; decoupling capacitor required within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| Inverting Input Logic | Eliminates need for external inverters in applications where controller outputs are non-inverting but gate drive requires inversion |
| Active Output Voltage Clamping | Clamps negative gate swing to –2.5 V during fast turn-off, preventing gate oxide stress without discrete Zener diodes |
| Dual Independent Enable Pins | ENA and ENB allow per-channel disable for fault recovery, soft-start sequencing, or dynamic topology reconfiguration |
| Industrial Qualification | Qualified per JEDEC JESD47 and JESD22 standards - rated for –40 °C to +125 °C ambient operation in harsh environments |
| SOT23-6 Footprint | Enables ultra-compact layout in high-density power modules and USB-C PD adapters with minimal PCB area and thermal mass |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2EDN7533BXTSA1 | 5 A peak output current vs. 4 A; identical pinout, logic, and UVLO | Better suited for higher-Qg MOSFETs (>50 nC) or higher-frequency operation (>2 MHz) | Select when driving larger FETs or requiring margin for aging/temperature derating |
| UCC27524ADRV | Non-inverting logic, 5 A drive, 17 ns delay, no active clamp, 3–18 V supply | Lacks built-in negative voltage clamp; requires external protection for high-dV/dt layouts | Choose if system uses non-inverting controller outputs and can accommodate external clamping |
Compared with 2EDN7433BXTSA1, the 2EDN7533BXTSA1 offers higher drive strength without layout change, while the UCC27524ADRV trades clamp functionality for broader supply range and non-inverting interface-making each suitable for distinct control architecture constraints.

FAQ
What logic configuration does 2EDN7433BXTSA1 use?
2EDN7433BXTSA1 uses inverting input logic: a high signal on INA or INB produces a low output on OUTA or OUTB, respectively. This matches common controller architectures that output active-high PWM for low-side switches, simplifying PCB routing and eliminating external inverters.
Does 2EDN7433BXTSA1 require external gate resistors?
No external gate resistors are required for basic operation, as the IC's 4 A drive strength and internal output impedance provide adequate control over MOSFET switching speed. However, small series resistors (≤5 Ω) may be added to damp ringing in high-dV/dt layouts or fine-tune rise/fall times for EMI optimization.
Can 2EDN7433BXTSA1 drive GaN HEMTs?
Yes-it supports GaN HEMTs with gate thresholds ≤3 V and Qg ≤35 nC at 1 MHz switching, thanks to its 4 A peak current, 19 ns propagation delay, and –2.5 V active clamp. Ensure VGS rating compliance and use low-inductance layout to avoid gate overshoot beyond ±6 V.
What is the thermal performance of the SOT23-6 package?
The PG-SOT23-6 package has a junction-to-ambient thermal resistance (RθJA) of 180 °C/W under standard 2-layer JEDEC test conditions. With 4 A drive at 50% duty cycle and 100 ns switching transitions, typical power dissipation is <0.35 W-keeping junction temperature below 105 °C at 85 °C ambient with minimal copper area.
