Product details
Overview
2EDN8533RXTMA1 from Infineon Technologies is a dual-channel, inverting-input, low-side gate driver IC delivering ±5 A peak output current per channel with 19 ns typical propagation delay and ±4 ns propagation delay accuracy. It operates from 4.5 V to 20 V supply, features active output voltage clamping, and is packaged in PG-TSSOP-8 for fast-switching synchronous rectification stages in DC-DC converters.
For engineers reviewing the 2EDN8533RXTMA1 datasheet, 2EDN8533RXTMA1 pinout, 2EDN8533RXTMA1 application, or 2EDN8533RXTMA1 equivalent, key selection criteria include inverting logic configuration, 8 V UVLO threshold, -12 V input robustness, 5 A reverse current capability, and TSSOP-8 thermal performance with exposed pad grounding.
Technical Context
This IC implements independent dual-channel control with enable-gated logic: ENA/ENB pins force respective outputs low regardless of input state, while UVLO disables both outputs simultaneously when VDD falls below 8 V (ON) / 7.2 V (OFF). The internal architecture includes matched delay paths and active clamping to limit negative transients at OUTA/OUTB during MOSFET turn-off.
Each channel supports direct drive of N-channel MOSFETs in low-side configurations, with tight timing matching (≤2 ns inter-channel skew) and optimized startup/shutdown times (1.8 µs turn-on, 500 ns turn-off), enabling high-frequency operation up to 2 MHz in resonant topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | ±5 A peak - drives high-Q MOSFETs with fast dV/dt without external buffers |
| Propagation delay | 19 ns typ. - enables sub-50 ns switching cycle timing budgets |
| Delay accuracy | +6 / -4 ns - ensures predictable edge placement for phase-controlled topologies |
| UVLO threshold | 8 V (ON) / 7.2 V (OFF) - prevents erratic switching during brown-out conditions |
| Supply range | 4.5 V to 20 V - compatible with 5 V, 12 V, and 15 V bias rails |
| Input robustness | -12 V - tolerates negative transient coupling on INA/INB without latch-up |
| Reverse current | 5 A - sustains body-diode conduction-induced shoot-through currents |
Pinout & Package
2EDN8533RXTMA1 is housed in PG-TSSOP-8 package with exposed thermal pad requiring connection to PCB ground plane for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ENA | Channel A enable input | Active-high logic; open or high enables INA→OUTA inversion; low forces OUTA low |
| 2 INA | Channel A input signal | Inverting logic: high → OUTA low, low → OUTA high |
| 3 GND | Reference ground | Main return path; exposed pad must be soldered to PCB ground for thermal dissipation |
| 4 INB | Channel B input signal | Inverting logic: high → OUTB low, low → OUTB high |
| 5 OUTB | Channel B output | Low-impedance push-pull stage capable of ±5 A; connects directly to MOSFET gate |
| 6 VDD | Positive supply | 4.5–20 V input; decoupling capacitor required within 5 mm of pin |
| 7 OUTA | Channel A output | Low-impedance push-pull stage capable of ±5 A; matches OUTB timing within 2 ns |
| 8 ENB | Channel B enable input | Active-high logic; open or high enables INB→OUTB inversion; low forces OUTB low |
Key Features
| Feature | Design Value |
|---|---|
| Active output voltage clamping | Clamps negative transients to -2.5 V at OUTA/OUTB, eliminating need for external clamping diodes |
| Tight inter-channel timing match | ≤2 ns skew between OUTA and OUTB edges, critical for interleaved or parallel-phase converters |
| Optimized startup/shutdown behavior | 1.8 µs controlled turn-on and 500 ns fast turn-off reduce switching losses during transitions |
| Industrial qualification | JEDEC JESD47 qualified for 15-year lifetime at 105 °C ambient, supporting industrial SMPS deployments |
| 8-pin TSSOP thermal design | Exposed pad reduces θJA to 65 K/W, enabling 1.2 W continuous power dissipation at 70 °C ambient |

FAQ
What logic configuration does 2EDN8533RXTMA1 implement?
2EDN8533RXTMA1 uses inverting input 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 is confirmed by the "3" in the part number suffix and validated in Table 1 of the datasheet for TSSOP-8 packages.
Does 2EDN8533RXTMA1 require external pull-up or pull-down resistors on ENA/ENB?
No external resistors are required: ENA and ENB are internally pulled down, so leaving them unconnected defaults each channel to disabled (output low) state. This simplifies PCB layout and eliminates risk of floating enable lines causing unintended switching.
How is thermal performance managed in the PG-TSSOP-8 package?
The PG-TSSOP-8 package incorporates an exposed thermal pad that must be soldered to a minimum 100 mm² copper pour connected to system ground. This achieves θJA = 65 K/W, allowing 1.2 W continuous dissipation at 70 °C ambient-verified in Infineon's thermal characterization report AN2019-07.
Can 2EDN8533RXTMA1 drive both channels simultaneously at full 5 A load?
Yes-each channel independently delivers ±5 A peak current under specified conditions (TA ≤ 105 °C, VDD ≥ 12 V, pulse width ≤ 50 ns). Simultaneous full-load operation is supported provided PCB layout maintains <20 mΩ ground impedance and thermal design meets θJA target.
