Product details
Overview
IR2214SS from International Rectifier is a high-voltage half-bridge gate driver IC designed to control N-channel MOSFETs or IGBTs in switching power converters. It supports up to 1200 V floating channel offset, delivers 2 A source / 3 A sink peak output current, features integrated desaturation detection, soft shutdown, and matched propagation delays (±75 ns). It is used in industrial motor drives and resonant LLC converters where robust fault management and noise immunity are critical.
For engineers reviewing the IR2214SS datasheet, IR2214SS pinout, IR2214SS application, or IR2214SS equivalent, key selection considerations include its 1200 V VS rating, dual-stage turn-on for di/dt control, separate pull-up/pull-down drive pins, 3 µs desat blanking time, and 3.3 V–compatible FAULT/SD interface with local multi-phase fault synchronization.
Technical Context
The IR2214SS implements independent undervoltage lockout (UVLO) on both low-side (VCC) and high-side (VB–VS) supplies, with 0.9 V hysteresis per rail. Its desaturation detection circuit monitors DSH and DSL inputs using 8.0 V threshold with 1.0 V hysteresis and 3 µs blanking after turn-on to avoid false triggering during switching transients.
Soft shutdown is triggered by desat events and executed via dedicated SSDH/SSDL outputs with 9.25 µs typical duration, reducing voltage overshoot and EMI. Synchronization across phases occurs through open-drain SY_FLT and FAULT/SD pins, enabling coordinated fault response without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 1200 V - supports high-side operation in 650 V/1200 V IGBT or SiC MOSFET half-bridge topologies |
| IO+ / IO− | 2 A / 3 A - sufficient gate drive strength for fast switching of 100–500 A IGBTs or high-Ciss SiC devices |
| Desat blanking time | 3 µs - suppresses false desat trips during Miller plateau and device turn-on transient |
| Soft shutdown time | 9.25 µs - controlled turn-off reduces dv/dt-induced overvoltage and EMI during fault conditions |
| Deadtime matching | 75 ns max - ensures consistent shoot-through prevention across temperature and supply variations |
| Input logic threshold | 2.0 V (VIH), 0.8 V (VIL) - compatible with 3.3 V CMOS controllers without level-shifting |
| UVLO hysteresis | 0.9 V - prevents oscillation near UVLO trip points during brown-out or startup |
Pinout & Package
IR2214SS is housed in a 24-lead SSOP (Shrink Small Outline Package) with exposed thermal pad, optimized for high-voltage isolation and thermal performance in compact power modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side logic supply input | Provides 11.5–20 V bias for internal logic and LOP/LON drivers; monitored by independent UVLO |
| COM | Low-side power ground reference | Return path for LOP/LON/DSL; enables emitter-current sensing with dedicated low-inductance routing |
| HIN | High-side input control | CMOS-compatible digital input controlling HOP/HON; 1 µs minimum pulse width requirement |
| LIN | Low-side input control | CMOS-compatible digital input controlling LOP/LON; synchronized deadtime generation with HIN |
| VB | High-side floating supply | Bootstrap or isolated supply referenced to VS; powers HOP/HON/SSDH and internal level shifter |
| VS | High-side floating return | Reference node for high-side circuitry; withstands up to 1200 V offset relative to COM |
| HOP / HON | High-side output pull-up / pull-down | Separate terminals enable external gate resistor tuning for di/dt control and EMI optimization |
| LOP / LON | Low-side output pull-up / pull-down | Separate terminals allow independent rise/fall shaping and reduce cross-conduction risk |
| DSH / DSL | High/low-side desaturation sense inputs | Monitor collector/emitter voltage of power devices; trigger soft shutdown on overcurrent or short-circuit |
| FAULT/SD | Fault status output / shutdown input | Open-drain 3.3 V–compatible signal for system-level fault reporting or forced shutdown |
| SY_FLT | Synchronization fault output | Open-drain signal for inter-phase fault coordination in multi-phase inverters or converters |
| FLT_CLR | Active-low fault clear input | Resets latched fault state after root cause removal; requires clean low-going pulse ≥100 ns |
Key Features
| Feature | Design Value |
|---|---|
| Dual-stage gate drive | First-stage 2 A pulse (≤200 ns), second-stage 1 A sustained drive - enables precise di/dt control and reduced switching loss |
| Matched propagation delay | ±75 ns max mismatch between HIN→HOP and LIN→LOP - ensures tight deadtime control across process/temperature |
| Independent UVLO rails | Separate VCC and VB–VS UVLO with hysteresis - prevents erratic operation during bootstrap recharge or supply sag |
| Soft shutdown with timing control | 9.25 µs fixed-duration SSDH/SSDL activation - limits dv/dt, avoids hard turn-off stress on power devices |
| Noise-immune ground separation | Dedicated COM and VS pins - isolates low-side emitter sensing path from high-side switching noise |

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 |
|---|---|---|---|
| IR2114SS | 600 V VS rating, identical pinout and feature set except lower offset voltage | Suitable for 650 V systems only; not rated for 1200 V bus operation | Select when cost-sensitive 600 V designs require drop-in compatibility and reduced thermal stress |
| IRS21844SPbF | Integrated bootstrap diode, no separate VB/VS pins; 600 V VS rating; no desat detection or SY_FLT | Lacks desat protection and multi-phase sync; suited for simpler, lower-power half-bridges | Choose for cost-optimized 300–500 W SMPS where fault coverage is handled externally |
Compared with IR2114SS and IRS21844SPbF, the IR2214SS uniquely supports 1200 V operation with full desat protection, soft shutdown, and inter-phase fault signaling-making it essential for high-reliability, high-voltage industrial and renewable energy inverters.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IR2214SS is rated for up to 50 V/ns dV/dt on the VS pin under normal operation. This specification ensures reliable level-shifting performance during fast-switching events in SiC or high-frequency IGBT applications, preventing false triggering or latch-up in the high-side driver section.
Can IR2214SS drive SiC MOSFETs directly?
Yes - its 2 A source / 3 A sink peak output current, 1200 V VS rating, and separate HOP/HON pins provide appropriate gate drive strength and layout flexibility for common 1200 V SiC MOSFETs. External gate resistors must be selected to limit di/dt per device requirements and avoid oscillation.
How does the desaturation blanking time interact with PWM frequency?
The fixed 3 µs blanking window starts at HIN or LIN rising edge and disables desat monitoring during turn-on. At 100 kHz PWM, this represents 30% of the 10 µs period - acceptable for most motor drives and LLC converters, but may require careful deadtime and modulation strategy in >300 kHz designs.
Is the FAULT/SD pin truly 3.3 V compatible?
Yes - the FAULT/SD pin has CMOS-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and operates with 3.3 V logic levels. Its open-drain output can be pulled up to 3.3 V or 5 V, making it interoperable with modern microcontrollers and FPGA I/O without level shifters.
