Product details
Overview
IR7184SPBF from Infineon Technologies (formerly International Rectifier) is a 700V high-voltage half-bridge gate driver IC with independent high-side and low-side output channels, designed to drive N-channel IGBTs and MOSFETs in bootstrap-configured inverters. It delivers ±2.3A peak output current, features integrated deadtime (400ns typ.) and shoot-through protection, and operates across –40°C to +125°C for appliance motor drives and micro-inverters.
For engineers reviewing the IR7184SPBF datasheet, IR7184SPBF pinout, IR7184SPBF application, or IR7184SPBF equivalent, key selection criteria include its 700V offset rating, matched propagation delays (680ns/270ns), 3.3V–15V logic compatibility, undervoltage lockout on both VCC and VBS, and SOIC-8 package suitability for space-constrained power stage layouts.
Technical Context
The IR7184SPBF integrates a rugged monolithic HVIC structure with latch-immune CMOS logic, enabling reliable operation under high dVS/dt transients (up to 50 V/ns). Its floating high-side channel references VS (not COM), supporting up to 700V offset between VB and VS while maintaining logic-level input compatibility down to 3.3V.
Internal circuitry includes dual UVLO comparators (8.9V threshold, 0.7V hysteresis) for VCC and VBS, a dedicated shutdown input (/SD), and pulse-filtered level-shifting that ensures robust noise immunity. Propagation delay matching (≤90ns MTON, ≤50ns MTOFF) simplifies timing control in high-frequency three-phase PWM systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 700V max - enables direct high-side switching in 600V-class DC bus applications without external level shifters |
| tON / tOFF | 680ns / 270ns typ. - supports >500 kHz PWM switching with predictable timing margins |
| Io+ / Io− | 1.9A / 2.3A typ. - sufficient to charge/discharge 1000pF gate capacitance within 40ns/20ns rise/fall times |
| Deadtime | 400ns typ. - prevents shoot-through during cross-conduction in half-bridge leg commutation |
| VIN Logic Range | 3.3V–15V compatible - interfaces directly with MCU GPIO, FPGA outputs, or isolated digital controllers |
| UVLO Threshold | VCC & VBS: 8.9V ±0.9V - ensures gate drive remains disabled until bootstrap and low-side supplies stabilize |
| Operating Temp | –40°C to +125°C - qualified for industrial motor control and outdoor micro-inverter environments |
Pinout & Package
IR7184SPBF is housed in an 8-lead SOIC (SO8N) package with standard 1.27mm pitch, surface-mount footprint, and exposed pad not present. Pin assignments are validated per official lead definition diagram: IN (1), /SD (2), COM (3), LO (4), VB (5), HO (6), VS (7), VCC (8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Logic input for both HO and LO | Single-input control simplifies PWM signal routing; inverted LO output generated internally |
| /SD | Active-low shutdown input | Pulls both outputs low when asserted; 0.8V max logic-0 threshold ensures noise margin |
| COM | Low-side return reference | Common ground for VCC, LO, and logic; must be low-inductance connection to minimize ground bounce |
| LO | Low-side gate driver output | Sinks up to 2.3A; referenced to COM; drives N-MOSFET/IGBT source terminal |
| VB | High-side floating supply rail | Connects to bootstrap capacitor top; supplies HO driver stage at VS + 10V to VS + 20V |
| HO | High-side gate driver output | Sources up to 1.9A; referenced to VS; drives N-MOSFET/IGBT gate above floating source |
| VS | High-side floating return | References HO output; tracks switching node voltage up to 700V offset from COM |
| VCC | Low-side logic and driver supply | 10–20V input powers internal logic, level shifter, and LO driver; requires local decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Integrated deadtime generation | Fixed 400ns minimum delay prevents simultaneous conduction in half-bridge legs without external timing components |
| Matched propagation delays | ≤90ns MTON and ≤50ns MTOFF ensure symmetrical PWM edge alignment for reduced current ripple |
| Dual independent UVLO | Separate 8.9V thresholds on VCC and VBS guarantee safe startup only when both supplies are valid |
| Bootstrap-compatible architecture | VS-referenced high-side channel eliminates need for isolated DC-DC or transformer-based gate supplies |
| Transient voltage tolerance | Rated for 50 V/ns dVS/dt - withstands fast-switching-induced coupling in compact inverter PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844PbF | Same SOIC-8 package; 600V offset rating; 2.5A/2.5A output; no integrated deadtime | Requires external deadtime circuitry; better suited for discrete timing control in custom gate drive designs | Choose when precise deadtime adjustment is required and 600V bus suffices |
| UCC27211DR | 600V offset; 4A/4A output; no bootstrap support; requires isolated supply for high-side | Designed for split-supply or transformer-isolated gate drive; higher peak current but more complex BOM | Prefer when driving SiC MOSFETs needing >3A peak or when isolated bias is already available |
Compared with IRS21844PbF and UCC27211DR, IR7184SPBF uniquely combines 700V offset, integrated deadtime, and bootstrap compatibility in SOIC-8-reducing component count and layout area for cost-sensitive 600V-class inverters without sacrificing reliability.

FAQ
What is the maximum allowable dVS/dt for IR7184SPBF?
The IR7184SPBF is rated for up to 50 V/ns dVS/dt on the VS node, verified under standard test conditions per datasheet Absolute Maximum Ratings. This specification ensures reliable level-shifting operation during fast switching transitions in 600V-class inverters, provided PCB layout minimizes parasitic inductance in the VS return path.
Can IR7184SPBF drive SiC MOSFETs?
IR7184SPBF can drive low-to-mid-power SiC MOSFETs with gate charge ≤100nC, given its 1.9A/2.3A peak output and 40ns/20ns rise/fall times. However, it lacks active Miller clamp and negative turn-off voltage-features recommended for robust SiC gate control in high-noise environments.
Is external deadtime required when using IR7184SPBF?
No external deadtime circuitry is required: the IR7184SPBF integrates fixed 400ns minimum deadtime between HO and LO outputs. This internal logic prevents shoot-through during commutation and eliminates the need for external RC networks or gate-delay resistors in standard half-bridge configurations.
What bootstrap capacitor value is recommended for IR7184SPBF?
A 0.1 µF X7R ceramic capacitor is recommended for the bootstrap capacitor, placed as close as possible to VB and VS pins. This value ensures adequate charge replenishment at 20 kHz PWM with 50% duty cycle while maintaining <100 mV ripple on VBS under 2.3A LO sink load, per application note DT97-3.
