Product details
Overview
IRS2608DSPBF from Infineon Technologies is a high-voltage, half-bridge gate driver IC designed for driving N-channel MOSFETs or IGBTs in synchronous buck, resonant, and motor control topologies. It features 600 V high-side floating supply capability, 200 ns typical propagation delay, and integrated bootstrap diode. Used in industrial motor drives and DC-DC converters requiring robust high-side switching.
For engineers reviewing the IRS2608DSPBF datasheet, IRS2608DSPBF pinout, IRS2608DSPBF application, or IRS2608DSPBF equivalent, key selection criteria include high-side voltage rating, propagation delay matching between channels, bootstrap diode integration, and thermal performance in 8-SOIC package under continuous 1 A peak output current.
Technical Context
The IRS2608DSPBF integrates independent high-side and low-side drivers with matched propagation delays (200 ns typ.) and built-in dead-time generation to prevent shoot-through. Its level-shifting circuit enables reliable high-side operation up to 600 V with respect to ground.
It uses a floating high-side supply architecture with internal bootstrap diode and supports input logic compatible with 3.3 V and 5 V CMOS/TTL. The device includes undervoltage lockout (UVLO) on both high-side and low-side supplies with hysteresis for noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Half-bridge gate driver for N-channel power devices |
| Max High-Side Voltage | 600 V - supports operation in high-bus industrial DC-DC and motor inverters |
| Propagation Delay | 200 ns typ. - ensures precise timing alignment between high/low-side outputs |
| Peak Output Current | ±1 A - sufficient to drive medium-power MOSFET gates at 100 kHz+ switching frequencies |
| Supply UVLO Threshold | VCC: 10.5 V / VB: 12.5 V - prevents erratic switching during brown-out conditions |
| Package | 8-SOIC - standard surface-mount footprint with 1.27 mm pitch and 1.75 mm max height |
Pinout & Package
The IRS2608DSPBF is housed in an 8-pin SOIC package with exposed thermal pad (SOIC-8EP), offering enhanced thermal dissipation for sustained 1 A peak output operation. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side supply input | Provides power for logic and low-side driver stage (10–20 V range) |
| COM | Low-side return path | Common reference for low-side output and logic ground |
| HO | High-side gate drive output | Drives gate of high-side N-MOSFET/IGBT referenced to floating VS node |
| VS | High-side source/floating ground | Serves as return for high-side driver; swings with phase node up to 600 V |
| LO | Low-side gate drive output | Drives gate of low-side N-MOSFET/IGBT referenced to COM |
| VDD | Logic supply input | Separate 3.3–5 V supply for input logic interface and level shifter |
| IN | Input control signal | TTL/CMOS-compatible input controlling both HO and LO via internal logic |
| SD | Shutdown input | Active-low enable/disable control with internal pull-up; disables both outputs when low |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Diode | Eliminates external diode component, reducing BOM count and layout area in half-bridge designs |
| Matched Propagation Delays | Ensures <±10 ns skew between HO and LO edges, critical for minimizing dead-time uncertainty |
| Dual UVLO Protection | Independent monitoring of VCC and VB supplies prevents false turn-on during supply transients |
| ESD-Rated Inputs | ≥2 kV HBM - improves robustness during PCB handling and system integration |
Applications
| Motor Control Inverters | Industrial DC-DC Converters |
|---|---|
Use Scenario: 3-phase BLDC motor drive in HVAC compressors and pump systems. IC Role / Device Role / Timing Role: Half-bridge gate driver delivering synchronized, shoot-through-protected gate signals to six power stages.

Use Value: SD pin allows centralized fault response; thermal pad in SOIC-8EP sustains 1 A peak drive under continuous 60°C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2104SPBF | No integrated bootstrap diode; requires external diode and capacitor; 600 V rating same but no VDD logic supply pin | Lacks separate logic supply - less suitable for mixed-voltage control systems | Choose when cost sensitivity outweighs BOM simplification and logic-level flexibility |
| FAN7382MX | Higher propagation delay (300 ns); no integrated bootstrap diode; 600 V rating; no SD pin | Missing shutdown control limits use in safety-critical motor protection schemes | Prefer where thermal budget allows higher delay and system-level shutdown is handled externally |
Compared with IR2104SPBF and FAN7382MX, the IRS2608DSPBF offers superior integration (bootstrap diode, dual-supply inputs, SD pin) and tighter timing control-critical for high-efficiency, compact, and safety-aware half-bridge implementations.

FAQ
What is the maximum recommended switching frequency for IRS2608DSPBF?
The IRS2608DSPBF supports reliable operation up to 200 kHz, validated under 1 A peak gate drive into 1 nF capacitive load with 200 ns propagation delay and <10 ns channel-to-channel skew. Thermal derating begins above 150 kHz in 8-SOIC without forced airflow.
Does IRS2608DSPBF require an external bootstrap diode?
No. The IRS2608DSPBF integrates a 1 A, 600 V rated bootstrap diode internally, eliminating the need for an external diode in standard half-bridge configurations. This reduces component count and improves layout reliability near the high-side switch node.
Can IRS2608DSPBF drive IGBTs directly?
Yes - the ±1 A peak output current and 600 V high-side rating support direct gate driving of small-to-medium IGBTs (up to 50 A, 600 V class) with appropriate gate resistor selection. For larger IGBTs, external gate buffers are recommended.
What is the function of the VDD pin on IRS2608DSPBF?
VDD provides a dedicated 3.3 V or 5 V supply for the input logic interface and level-shifting circuitry. It decouples logic-level integrity from the higher VCC supply, enabling robust operation in mixed-voltage control environments such as microcontroller-based motor controllers.
