Product details
Overview
2EDN7533RXTMA1 from Infineon Technologies is a dual-channel, inverting-input, low-side gate driver IC delivering ±5 A peak output current with 19 ns typical propagation delay and ±4 ns propagation delay accuracy. It features active output voltage clamping, 4 V UVLO, and operates from 4.5 V to 20 V supply-designed for synchronous rectification stages in high-frequency DC-DC converters.
For engineers reviewing the 2EDN7533RXTMA1 datasheet, 2EDN7533RXTMA1 pinout, 2EDN7533RXTMA1 application, or 2EDN7533RXTMA1 equivalent, key selection criteria include inverting logic configuration, TSSOP-8 package compatibility, tight timing control for <100 ns dead-time management, and robust −12 V input tolerance in noisy power stage environments.
Technical Context
This IC implements independent dual-channel logic with enable-controlled outputs: ENA/ENB override INA/INB to force OUTA/OUTB low, while UVLO disables both outputs simultaneously when VDD drops below 4 V (rising) or 3.5 V (falling). The inverting configuration means high INA drives OUTA low and vice versa.
Its driver stage uses optimized bipolar-CMOS-DMOS (BCD) process technology to achieve low 0.6 Ω typical output resistance (RDS(on)), enabling fast MOSFET turn-on/turn-off with 1.8 µs startup and 500 ns shutdown times-critical for minimizing conduction loss in high-efficiency synchronous buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±5 A - sufficient to drive 10–20 nC gate charge MOSFETs at >1 MHz switching frequencies without external buffers. |
| Propagation Delay | 19 ns typ. - enables precise timing alignment between channels for sub-50 ns dead-time control in synchronous rectifiers. |
| Delay Accuracy | +6/−4 ns - ensures channel-to-channel skew remains within 10 ns, reducing shoot-through risk in half-bridge configurations. |
| UVLO Threshold | 4 V (ON), 3.5 V (OFF) - provides stable operation down to 4.5 V supply while preventing erratic switching during brown-out conditions. |
| 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. |
| Input Robustness | −12 V tolerance - withstands negative transients on INA/INB pins during layout coupling or ESD events. |
| Output Shutdown Time | 500 ns - guarantees rapid MOSFET turn-off during fault conditions, limiting short-circuit energy dissipation. |
Pinout & Package
2EDN7533RXTMA1 is packaged in PG-TSSOP-8 (RoHS-compliant, leaded, 3.0 mm × 4.4 mm body, 0.65 mm pitch), featuring an exposed thermal pad that must be soldered to PCB ground for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ENA | Channel A Enable Input | Active-high logic input; open or high enables INA→OUTA inversion; low forces OUTA low regardless of INA state. |
| 2 INA | Channel A Inverting Input | Logic signal controlling OUTA with inverted polarity: INA = high → OUTA = low; INA = low → OUTA = high. |
| 3 GND | Power Ground Reference | Main return path for driver currents; exposed pad must be connected to system ground plane for thermal and noise integrity. |
| 4 INB | Channel B Inverting Input | Logic signal controlling OUTB with inverted polarity: INB = high → OUTB = low; INB = low → OUTB = high. |
| 5 OUTB | Channel B Low-Side Output | Low-impedance push-pull output capable of ±5 A; directly drives N-channel MOSFET gate with minimal RC time constant. |
| 6 VDD | Positive Supply Input | Primary power rail (4.5–20 V); internal UVLO and logic circuits derive bias from this node. |
| 7 OUTA | Channel A Low-Side Output | Low-impedance push-pull output identical to OUTB; matched timing ensures symmetrical drive in dual-phase applications. |
| 8 ENB | Channel B Enable Input | Active-high logic input; open or high enables INB→OUTB inversion; low forces OUTB low regardless of INB state. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting logic configuration | Supports direct integration with PWM controllers that output complementary signals without external inverters-reducing component count and propagation delay. |
| Active output voltage clamping | Limits OUTA/OUTB voltage to ≤VDD + 0.3 V during Miller plateau transitions, preventing gate overvoltage and improving MOSFET reliability. |
| 5 A reverse current robustness | Withstands 5 A reverse di/dt during MOSFET body diode conduction without latch-up-essential for synchronous rectifier operation with fast current reversal. |
| Tight propagation delay matching | ≤10 ns inter-channel skew ensures consistent timing across both outputs, enabling accurate dead-time implementation in multi-phase converters. |
| Industrial qualification per JEDEC | Rated for −40 °C to +125 °C ambient operation with 100% production test coverage-validated for long-term reliability in industrial SMPS and server VRMs. |

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 |
|---|---|---|---|
| 2EDN7534RXTMA1 | Non-inverting logic configuration; otherwise identical pinout, timing, and electrical specs. | Requires complementary PWM inputs instead of inverted signals; suited for controllers with non-inverted outputs. | Select when system controller outputs match non-inverting logic convention-no external inverters needed. |
| UCC27531DR | Single-channel, non-inverting, 5 A driver in SOIC-8; lacks enable pins and UVLO hysteresis (3.5 V/2.9 V). | Not pin-compatible; requires two units for dual-channel use and additional logic for enable/UVLO coordination. | Consider only if design already uses TI ecosystem and can accommodate discrete enable/UVLO circuitry. |
Compared with 2EDN7534RXTMA1, the 2EDN7533RXTMA1 saves board space by eliminating external inverters; versus UCC27531DR, it delivers integrated dual-channel control with tighter timing and robust enable/UVLO functionality-reducing BOM count and improving system-level timing predictability.

FAQ
What logic configuration does 2EDN7533RXTMA1 implement?
2EDN7533RXTMA1 implements inverting logic: a high signal on INA or INB forces the corresponding output (OUTA or OUTB) low, and a low input drives the output high. This matches controllers that output active-low gate signals or require inverted drive for synchronous rectifier timing alignment.
Can 2EDN7533RXTMA1 drive GaN HEMTs?
Yes-its 19 ns propagation delay, ±5 A peak current, and 500 ns shutdown time meet critical timing and drive strength requirements for enhancement-mode GaN FETs with gate charges under 15 nC. However, external gate resistors and negative turn-off bias may still be needed for optimal dV/dt control.
Is the exposed thermal pad on the TSSOP-8 package required to be grounded?
Yes-the exposed pad on 2EDN7533RXTMA1's PG-TSSOP-8 package must be soldered to a PCB copper pour connected to GND. This provides primary thermal dissipation (reducing junction temperature by up to 25 °C) and lowers high-frequency impedance for cleaner gate drive waveforms.
Does 2EDN7533RXTMA1 support independent UVLO per channel?
No-UVLO is global: when VDD falls below the 4 V threshold, both OUTA and OUTB are forced low simultaneously, regardless of individual ENA/ENB or INA/INB states. This ensures fail-safe shutdown of the entire driver stage during supply faults.
