Product details
Overview
IR22141SS from Infineon Technologies (formerly International Rectifier) is a high-voltage half-bridge gate driver IC with 1200 V floating channel capability, 2 A source / 3 A sink output drive, integrated desaturation detection, soft shutdown, and synchronized multi-phase fault management. It drives N-channel MOSFETs or IGBTs in industrial motor drives and UPS inverters requiring robust short-circuit protection.
For engineers reviewing the IR22141SS datasheet, IR22141SS pinout, IR22141SS application, or IR22141SS equivalent, key selection criteria include its 1200 V offset rating, dual-stage turn-on for di/dt control, matched 330 ns deadtime, 3 µs desat blanking time, and 3.3 V–compatible FAULT/SD interface for system-level fault coordination.
Technical Context
The IR22141SS implements independent undervoltage lockout on both low-side (VCC) and high-side (VB–VS) supplies, each with 0.9 V hysteresis. Its desaturation detection circuit monitors DSH and DSL pins with 8.0 V threshold and 1.0 V hysteresis, enabling fast fault response via dedicated soft shutdown outputs (SSDH/SSDL).
It supports multi-phase synchronization through SY_FLT and FAULT/SD signals, allowing coordinated shutdown across phases during cross-conduction or phase-to-phase faults. The two-stage turn-on (120–280 ns first stage, then second stage) provides controlled di/dt to reduce EMI and voltage overshoot during switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 1200 V max - enables direct driving of high-side switches in 650 V/1200 V IGBT or SiC MOSFET half-bridges without external level shifters. |
| IO+/IO− | 2 A source / 3 A sink - delivers sufficient peak current to rapidly charge/discharge gate capacitance of up to 20 nF devices at 100 kHz switching. |
| Deadtime (typ) | 330 ns - ensures reliable shoot-through prevention between high- and low-side drivers in hard-switched topologies. |
| Desat blanking time (typ) | 3 µs - suppresses false triggering during switching transients while retaining sensitivity to true over-current events. |
| Soft shutdown time (typ) | 9.25 µs - ramps down gate voltage gradually to limit dv/dt and suppress voltage spikes during fault conditions. |
| VIN logic threshold | 2.0 V min HI / 0.8 V max LO - compatible with 3.3 V CMOS microcontrollers without level translation. |
| tDESAT2 propagation delay | 1050 ns - defines maximum latency between desat event and soft shutdown activation after blanking period ends. |
Pinout & Package
IR22141SS is housed in a 24-lead SSOP (Shrink Small Outline Package) with exposed thermal pad, optimized for surface-mount assembly and thermal dissipation in power modules and motor drive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side logic supply input | Provides regulated 11.5–20 V bias for internal logic and low-side driver stage; monitored by UVLO with 9.3 V trip. |
| COM | Low-side power ground | Reference for LOP/LON/SSDL outputs and DSL input; enables emitter current sensing in IGBT configurations. |
| VB | High-side floating supply input | Bootstrap or isolated supply input referenced to VS; powers high-side driver stage and internal level shifter. |
| VS | High-side floating ground reference | Switch node connection point; supports up to 1200 V offset relative to COM, defining floating channel range. |
| HIN | High-side logic input | CMOS-compatible digital input controlling HOP/HON outputs; 2.0 V minimum VIH ensures noise margin in noisy environments. |
| LIN | Low-side logic input | Independent CMOS input for LOP/LON; allows asymmetric PWM or independent control of both bridge legs. |
| FAULT/SD | Open-drain fault status & shutdown input | 3.3 V–compatible bidirectional pin: asserts low during fault, accepts low pulse to clear latched faults. |
| SY_FLT | Synchronization fault signal output | Drives open-drain output to coordinate shutdown across multiple IR22141SS devices in multi-phase systems. |
| DSH | High-side desaturation sense input | Monitors IGBT collector or MOSFET drain via RC network; triggers soft shutdown when voltage exceeds 8.0 V. |
| DSL | Low-side desaturation sense input | Same function as DSH but referenced to COM; enables full-bridge desat coverage without external comparators. |
| SSDH | High-side soft shutdown output | Active-low open-drain output that pulls down HOP gate during desat event; bypasses normal logic path for safety. |
| SSDL | Low-side soft shutdown output | Active-low open-drain output tied to LOP gate; works in tandem with SSDH for simultaneous fault response. |
| HOP | High-side pull-up output | Source-only output stage (2 A); connects to gate of high-side N-channel device via external resistor. |
| HON | High-side pull-down output | Sink-only output stage (3 A); provides fast discharge path for high-side gate during turn-off. |
| LOP | Low-side pull-up output | Source-only output (2 A); drives low-side gate with controlled di/dt using external series resistor. |
| LON | Low-side pull-down output | Sink-only output (3 A); ensures rapid low-side turn-off even under high capacitive load. |
| FLT_CLR | Active-low fault clear input | Asynchronous reset pin: low pulse clears latched fault state and re-enables outputs after fault condition clears. |
| VSS | Logic ground reference | Internal logic ground; electrically isolated from COM and VS to support level-shifted communication paths. |
Key Features

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 | 600 V offset rating, no integrated desat detection, single-stage output drive, 500 ns typical deadtime | Suitable for lower-voltage MOSFET-based SMPS or PFC stages where desat protection is handled externally | Select when cost sensitivity outweighs need for 1200 V operation or integrated fault protection |

FAQ
What is the maximum allowable dV/dt on the VS pin for reliable operation?
The IR22141SS specifies a maximum allowable dV/dt of 50 V/ns on the VS pin under all operating conditions. This rating ensures robust noise immunity during fast-switching events in 1200 V IGBT applications. Exceeding this rate may cause false triggering of the level-shifting circuitry or premature UVLO activation. Layout best practices-including minimized loop area between VS, VB, and bootstrap capacitor-must be followed to stay within this limit.
Can the FAULT/SD pin be used as a standalone fault indicator without connecting to a controller?
Yes-the FAULT/SD pin operates as an open-drain output that pulls low during any detected fault (desat, UVLO, or logic error) and remains latched until cleared by either a low pulse on FLT_CLR or cycling VCC. It can directly drive an LED or optocoupler for local status indication without MCU involvement, though active fault clearing requires external signal assertion.
How does the two-stage turn-on improve EMI performance compared to single-stage drivers?
The two-stage turn-on separates gate charging into a low-current initial phase (120–280 ns @ 1–2 A) followed by full-current drive. This limits di/dt during Miller plateau crossing, reducing high-frequency harmonic content in the switching node voltage waveform. Measured data shows up to 12 dB reduction in 30–100 MHz conducted EMI versus single-stage equivalents under identical layout and load conditions.
Is the IR22141SS pin-compatible with the earlier IR21141SS variant?
No-while functionally similar, the IR22141SS and IR21141SS differ in pin assignment for SY_FLT and FAULT/SD. In the IR22141SS, SY_FLT is on Pin 23 and FAULT/SD on Pin 24; in the IR21141SS, these are swapped. PCB layout must be revised for direct replacement, and the higher 1200 V offset rating of IR22141SS does not imply backward compatibility in 600 V–optimized designs.
