Product details
Overview
IR7184STRPBF from Infineon Technologies (formerly International Rectifier) is a 700V half-bridge gate driver IC designed to control high-side and low-side N-channel MOSFETs or IGBTs in bootstrap-configured inverters. It delivers 1.9A source / 2.3A sink peak output current, features matched 680ns/270ns propagation delays, integrated 400ns deadtime, and dual undervoltage lockout (VCC & VBS). Used in appliance motor drives and micro-inverters.
For engineers reviewing the IR7184STRPBF datasheet, IR7184STRPBF pinout, IR7184STRPBF application, or IR7184STRPBF equivalent, key selection criteria include bootstrap-compatible floating channel operation up to 700V offset, 3.3V–5V logic compatibility, shoot-through protection, and thermal robustness across –40°C to +125°C ambient.
Technical Context
The IR7184STRPBF integrates two independent gate drivers - one referenced to COM (low-side), one referenced to VS (high-side floating) - with level-shifted logic inputs and HVIC-based isolation. Its internal deadtime generator enforces minimum 280–520ns non-overlap between HO and LO outputs, preventing cross-conduction under all operating conditions including transient dVS/dt up to 50V/ns.
Proprietary latch-immune CMOS and high-voltage IC technologies enable reliable operation at VS = VB − COM up to 700V. The device accepts standard CMOS/LSTTL logic inputs (VIH ≥ 2.7V, VIL ≤ 0.8V), supports shutdown via active-low /SD, and maintains stable drive strength across VCC = 10–20V and VB = VS + 10V to VS + 20V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 700V max floating offset - enables direct high-side drive in 600V-class bridge topologies without external level shifters |
| IO+ / IO− | 1.9A / 2.3A typical pulsed output - sufficient to rapidly charge/discharge 10nF gate capacitance in <100ns |
| tON / tOFF | 680ns / 270ns typical - ensures tight timing control for >100kHz PWM switching with minimal phase skew |
| Deadtime | 400ns typical - hardware-enforced minimum off-time prevents shoot-through during fast transitions |
| VIN Logic | 3.3V/5V/15V compatible - interfaces directly with MCU GPIO, FPGA I/O, or isolated digital controllers |
| UVLO Thresholds | VCC: 8.2V (±0.7V hysteresis); VBS: 8.2V (±0.7V hysteresis) - prevents erratic switching during brown-out or bootstrap capacitor discharge |
| Operating Temp | –40°C to +125°C - qualified for industrial motor control and outdoor micro-inverter environments |
Pinout & Package
IR7184STRPBF uses an 8-lead SOIC (SO8N) package with exposed pad for thermal enhancement. Pin 1 is IN; pin 2 is /SD; pin 3 is COM; pin 4 is LO; pin 5 is VB; pin 6 is HO; pin 7 is VS; pin 8 is VCC. All pins are surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Logic input for both HO and LO outputs | Drives high-side and low-side channels simultaneously; TTL/CMOS compatible |
| /SD | Active-low shutdown input | Pulls both outputs low when asserted; internal pull-up not present - requires external bias |
| COM | Low-side reference and power ground | Return path for VCC supply and LO output; must be low-inductance connection to PCB ground plane |
| LO | Low-side gate driver output | Sinks up to 2.3A to drive N-MOSFET/IGBT gates referenced to COM |
| VB | High-side floating supply input | Connects to bootstrap capacitor top node; supplies HO driver stage referenced to VS |
| HO | High-side gate driver output | Sources up to 1.9A to drive N-MOSFET/IGBT gates referenced to VS |
| VS | High-side floating return | Reference node for HO output and VB supply; tracks switching node voltage up to 700V offset |
| VCC | Logic and low-side supply input | Provides power for internal logic, level shifter, and LO driver; regulated 10–20V required |
Key Features
| Feature | Design Value |
|---|---|
| Integrated deadtime generator | Hardware-enforced 280–520ns minimum non-overlap eliminates need for external timing components or firmware compensation |
| Matched propagation delays | ≤90ns MTON/MTOFF mismatch ensures symmetrical edge alignment critical for high-frequency three-phase PWM |
| Dual UVLO with hysteresis | Independent 0.7V hysteresis on VCC and VBS prevents oscillation during marginal supply conditions |
| Bootstrap-compatible architecture | VS-referenced high-side channel operates with simple diode-capacitor bootstrap network - no isolated DC/DC required |
| Robust dVS/dt immunity | Rated for 50V/ns transients - suppresses false triggering in hard-switching inverter applications |

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 |
|---|---|---|---|
| IRS21844SPBF | Same SOIC-8 package; 600V offset; 2.5A/2.5A drive; no integrated deadtime - requires external RC timing | Lacks hardware deadtime; suitable where precise external timing control is preferred over fixed safety margin | Choose if design requires programmable deadtime or higher peak current than IR7184STRPBF |
| UCC27211D | 600V offset; 4A/4A drive; no integrated UVLO on floating supply; separate HO/LO inputs | Requires external bootstrap UVLO monitoring; supports independent high/low control for advanced modulation schemes | Choose for high-current SiC gate driving where dual-input flexibility outweighs integrated protection simplicity |
Compared with IRS21844SPBF and UCC27211D, the IR7184STRPBF offers superior system-level robustness via built-in deadtime and dual UVLO - reducing BOM count and layout sensitivity - while trading off some peak current and input flexibility for plug-and-play reliability in cost-sensitive inverter designs.

FAQ
What is the maximum allowable dVS/dt for reliable operation?
The IR7184STRPBF is rated for 50V/ns dVS/dt on the VS node. This specification ensures immunity to false triggering during fast switching transitions in 600V-class inverters. Operation beyond this limit may cause unintended HO turn-on due to capacitive coupling into the level shifter. Layout best practices-such as minimizing VS node loop area and using low-inductance bootstrap paths-are essential to maintain this rating in practice.
Can IR7184STRPBF drive SiC MOSFETs?
Yes, IR7184STRPBF can drive discrete SiC MOSFETs in half-bridge configurations, provided gate resistance and layout minimize ringing. Its 1.9A/2.3A peak drive strength supports typical 10–20nF SiC gate charges at ≤50kHz. However, its 700V offset rating and lack of dedicated SiC-specific features (e.g., negative turn-off voltage) mean it is best suited for 650V-class SiC devices in non-isolated, bootstrap-fed topologies.
Is an external bootstrap diode required?
Yes, an external fast-recovery bootstrap diode (e.g., 1N4148WS or equivalent) is mandatory between VCC and VB to charge the bootstrap capacitor during LO conduction. The diode must withstand reverse voltage ≥ VCC and support peak forward current ≥ 10mA. A low-forward-voltage Schottky diode is recommended to minimize voltage drop and improve high-side supply stability under heavy load.
Does IR7184STRPBF support 3.3V-only logic without level shifting?
Yes, the IN and /SD inputs are fully compatible with 3.3V logic: VIH(min) = 2.7V and VIL(max) = 0.8V, with internal 5.2V zener clamping. No external level shifter is needed when driven by 3.3V MCU GPIOs. However, ensure the /SD pin is actively pulled high (e.g., via 10kΩ to VCC) when not in use, as it has no internal pull-up.
