Product details
Overview
2EDL8124GXUMA1 from Infineon is a junction-isolated dual-channel gate driver IC with differential input, 4 A source/5 A high-side sink and 6 A low-side sink current capability, 120 V integrated bootstrap diode, and <6 ns delay matching-designed for synchronous rectification in isolated DC-DC converters operating up to 1 MHz.
For engineers reviewing the 2EDL8124GXUMA1 datasheet, 2EDL8124GXUMA1 pinout, 2EDL8124GXUMA1 application, or 2EDL8124GXUMA1 equivalent, key selection criteria include differential-input shoot-through immunity, -8 V to +15 V common-mode input rejection, 8–17 V supply range, UVLO thresholds (VDD: 7.0 V / VHB: 5.75 V), and PG-VDSON-8 package thermal performance.
Technical Context
This device implements a level-shifted dual-channel architecture where the high-side driver uses an on-chip 120 V bootstrap diode and external capacitor for floating rail generation. The differential input stage enforces complementary output behavior via hardware-level truth table logic (LI/HI = H/L → HO=L, LO=H; LI/HI = L/H → HO=H, LO=L), eliminating software-dependent dead-time control.
UVLO is implemented synchronously for both VDD and VHB rails-with 0.5 V hysteresis on VDD and 0.25 V on VHB-and includes 5 µs delay plus PWM synchronization to prevent HO activation during marginal boot voltage conditions. Output impedance is specified at 0.5 Ω (HS) and 0.35 Ω (LS) to suppress dv/dt-induced re-turn-on.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Source Current | 4 A per channel-enables fast turn-on of large gate-charge MOSFETs without external buffers. |
| Output Sink Current | 5 A (HS), 6 A (LS)-ensures rapid turn-off and robust Miller plateau discharge under high dv/dt. |
| Delay Matching | <6 ns-guarantees volt-second balance across transformer windings, preventing core saturation in phase-shifted topologies. |
| Input Common-Mode Range | -8 V to +15 V-tolerates ground bounce and noise in high-current switching nodes without latch-up. |
| VDD Operating Range | 8 V to 17 V-supports wide-input industrial supplies while maintaining UVLO protection down to 7.0 V threshold. |
| Bootstrap Diode Rating | 120 V-eliminates need for external high-voltage bootstrap diode in 100 V-class half-bridge designs. |
| Max Switching Frequency | 1 MHz-validates use in high-density GaN-based telecom and datacom SMPS. |
Pinout & Package
2EDL8124GXUMA1 is housed in a lead-free, RoHS-compliant PG-VDSON-8 (4 mm × 4 mm) package with exposed thermal pad. Pin assignments are validated per Infineon's datasheet Rev. 2.9 (2025-10-22), Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Gate drive supply input | Primary 8–17 V supply for internal logic and low-side driver; powers 3.3 V regulator for level shifters. |
| HB | High-side bootstrap rail | Connects to external bootstrap capacitor; referenced to HS node; supports 120 V max differential voltage. |
| HO | High-side gate output | Drives high-side MOSFET gate; features 0.5 Ω pull-down impedance to suppress dv/dt-induced false turn-on. |
| HS | High-side source connection | Switching node reference for high-side driver; rated for -(24 − VDD) V negative swing during hard commutation. |
| HI | Differential high-side input | One leg of true differential pair; requires complementary signal with LI to enforce shoot-through prevention. |
| LI | Differential low-side input | Second leg of differential pair; combined HI/LI state determines HO/LO output per Table 2 truth table. |
| VSS | Ground return | Internal connection to exposed thermal pad; must be soldered to PCB ground plane for thermal and EMI performance. |
| LO | Low-side gate output | Drives low-side MOSFET gate; 0.35 Ω pull-down impedance ensures clean turn-off in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Differential input logic | Hardware-enforced complementary outputs eliminate need for external dead-time circuitry or firmware timing margins. |
| Inherent shoot-through protection | Truth-table-driven output states (e.g., HI=H/LI=L → HO=L/LO=H) guarantee mutual exclusivity without timing dependency. |
| Integrated 120 V bootstrap diode | Reduces BOM count and layout area vs. discrete diode solutions; qualified for 100 V-class half-bridge operation. |
| Synchronous dual-rail UVLO | VDD and VHB UVLO release is coordinated with PWM edge to prevent HO activation during marginal boot voltage recovery. |
| Ultra-low output impedance | 0.5 Ω (HS) / 0.35 Ω (LS) pull-down enables reliable gate discharge even under >50 V/ns dv/dt transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2007PBF | Single-ended input, no differential logic; 2.5 A source/2.5 A sink; no integrated bootstrap diode. | Lacks inherent shoot-through protection; requires external bootstrap diode and dead-time control. | Lower cost for non-critical applications where layout-controlled dead time is acceptable. |
| UCC27211D | Dual independent inputs; 4 A source/4 A sink; no integrated bootstrap diode; 100 V max bootstrap rating. | Requires external 120 V bootstrap diode; lacks common-mode input tolerance (-8 V to +15 V). | Better for designs needing independent control but less demanding on noise immunity and bootstrap integration. |
Compared with IRS2007PBF and UCC27211D, 2EDL8124GXUMA1 delivers superior system robustness through hardware-enforced shoot-through prevention, integrated 120 V bootstrap diode, and extended input common-mode range-reducing design risk in high-noise telecom/datacom power stages.

FAQ
What is the function of the HS pin in 2EDL8124GXUMA1?
The HS (high-side source) pin serves as the switching node reference for the high-side driver and connects directly to the source terminal of the high-side MOSFET. It is rated for negative voltage excursions down to –(24 − VDD) V, enabling robust operation during hard commutation events caused by parasitic inductance. This pin forms the local ground for the high-side level shifter and must be routed with minimal inductance to ensure accurate bootstrap capacitor charging.
Does 2EDL8124GXUMA1 require an external bootstrap diode?
No. 2EDL8124GXUMA1 integrates a 120 V rated bootstrap diode internally, eliminating the need for an external diode in most 100 V-class half-bridge applications. This reduces BOM count, PCB area, and layout complexity while improving reliability-provided the external bootstrap capacitor is correctly sized per Infineon's Application Note AN2019-05 for VDSON-8 thermal performance.
How does the differential input prevent shoot-through?
The differential input enforces complementary output behavior via hardware logic: only HI=H/LI=L activates LO, and only HI=L/LI=H activates HO. Simultaneous HI/LI=H or L forces both outputs low. This truth-table implementation prevents concurrent high-side and low-side conduction regardless of controller timing errors or propagation delays-providing deterministic shoot-through immunity without software or external circuitry.
What is the purpose of the 5 µs delay in the high-side UVLO circuit?
The 5 µs delay in the high-side UVLO circuit ensures that the HO output remains blocked until the bootstrap voltage (VHB) has stabilized after UVLO release-preventing partial gate drive that could cause high conduction losses or thermal runaway. This delay is synchronized with the PWM signal so HO only propagates when HI is low at UVLO release, guaranteeing safe startup and recovery from brown-out conditions.
