Product details
Overview
IR22141SSPBF from Infineon Technologies (formerly International Rectifier) is a high-voltage half-bridge gate driver IC designed for IGBT and MOSFET power stages in industrial motor drives and UPS systems. It supports up to 1200 V floating channel operation, delivers 2 A source / 3 A sink peak output drive, features integrated desaturation detection with 3 µs blanking time, and implements soft shutdown with 9.25 µs typical duration to suppress voltage overshoot during fault events.
For engineers reviewing the IR22141SSPBF datasheet, IR22141SSPBF pinout, IR22141SSPBF application, or IR22141SSPBF equivalent, key selection criteria include its dual-stage turn-on capability for di/dt control, matched 330 ns deadtime with ≤75 ns mismatch, independent UVLO on VCC and VB–VS rails, and 3.3 V-compatible FAULT/SD and SY_FLT signaling for multi-phase fault coordination.
Technical Context
The IR22141SSPBF integrates two independent gate drivers - high-side (HOP/HON/SSDH) and low-side (LOP/LON/SSDL) - with separate pull-up/pull-down terminals enabling external current limiting and optimized switching transitions. Its desaturation detection circuit monitors DSH and DSL pins with 8.0 V threshold and 1.0 V hysteresis, triggering soft shutdown only after blanking intervals to avoid false trips during turn-on transients.
Communication between phases occurs via dedicated open-drain SY_FLT and FAULT/SD pins, supporting synchronized fault response across multi-phase inverters. The device uses isolated ground references (VSS for logic, COM for power) and withstands dV/dt up to 50 V/ns on the VS node, ensuring robust noise immunity in high dv/dt environments like SiC-based converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 1200 V - Enables direct driving of high-side switches in 650 V and 1200 V IGBT/SiC modules without level-shifting. |
| IO+ / IO− | 2 A / 3 A - Sufficient gate charge delivery for fast turn-on/turn-off of 100 A+ IGBTs at 15 kHz switching frequency. |
| Deadtime (typ) | 330 ns - Internally generated non-overlap interval prevents shoot-through in half-bridge configurations. |
| Desat blanking time | 3 µs - Fixed delay after switch turn-on before desat monitoring activates, avoiding false triggers from Miller plateau. |
| Soft shutdown time | 9.25 µs - Controlled ramp-down of gate voltage reduces di/dt and limits Vce overshoot during over-current events. |
| VCC & VBS UVLO | 10.2 V ±0.9 V - Independent undervoltage lockout on both logic and floating supplies ensures safe startup and fault recovery. |
| Propagation delay match | ≤75 ns - Tight matching between high-side and low-side turn-on/turn-off delays maintains precise timing symmetry. |
Pinout & Package
IR22141SSPBF is housed in a 24-lead SSOP (Shrink Small Outline Package) with exposed thermal pad, rated for surface-mount assembly and capable of dissipating 1.5 W under still-air conditions (RthJA = 65 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side logic supply input | Provides 11.5–20 V bias for internal logic, UVLO threshold at 10.2 V ensures stable operation. |
| COM | Power ground reference | Return path for low-side driver outputs and DSL input; enables emitter current sensing. |
| HIN | High-side logic input | CMOS-compatible (2.0 V VIH), controls HOP/HON with propagation delay of 440 ns typ. |
| LIN | Low-side logic input | CMOS-compatible (2.0 V VIH), controls LOP/LON with matched delay to HIN for deadtime integrity. |
| VB | Floating high-side supply | Bootstrap or isolated supply referenced to VS; must exceed VS + 11.5 V for reliable operation. |
| VS | Floating high-side return | Connects to IGBT collector or MOSFET drain; supports up to 1200 V offset relative to VSS. |
| DSH | High-side desaturation sense | Monitors IGBT saturation voltage via external resistor-divider; triggers soft shutdown if >8.0 V. |
| DSL | Low-side desaturation sense | Same function as DSH but referenced to COM; enables independent fault detection on both legs. |
| FAULT/SD | Bi-directional fault I/O | 3.3 V CMOS-compatible open-drain pin used to assert fault or accept system-wide shutdown command. |
| SY_FLT | Synchronization fault output | Open-drain signal indicating local fault; propagates to other phases to coordinate multi-phase shutdown. |
| HOP / HON | High-side pull-up / pull-down outputs | Separate terminals allow external gate resistors for independent turn-on/turn-off control and di/dt tuning. |
| LOP / LON | Low-side pull-up / pull-down outputs | Same architecture as high-side; supports asymmetric gate drive for optimized switching loss trade-offs. |
| SSDH / SSDL | Soft shutdown control outputs | Active-low signals that override normal outputs during desat event; drive external gate resistors for controlled turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-stage turn-on output | First stage delivers 2 A pulse for rapid Miller plateau crossing; second stage sustains 1 A for full gate charge, enabling precise di/dt control. |
| Integrated desaturation detection | On-chip comparator with 8.0 V threshold and 1.0 V hysteresis eliminates need for external op-amps or comparators in over-current protection circuits. |
| Matched delay outputs | ≤75 ns propagation delay mismatch between high-side and low-side paths ensures consistent deadtime across temperature and supply variations. |
| Independent UVLO on VCC and VB–VS | Prevents erratic behavior during bootstrap capacitor recharge or logic supply brownout by disabling respective driver sections independently. |
| Dedicated SY_FLT and FAULT/SD pins | Enables deterministic inter-phase fault communication without microcontroller intervention, critical for grid-tied inverter safety compliance. |

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IR22141SSPBF is rated for up to 50 V/ns dV/dt on the VS pin under normal operating conditions. This specification ensures reliable operation when driving fast-switching devices like SiC MOSFETs, provided layout minimizes parasitic inductance and ground separation between COM and VSS is maintained per datasheet guidelines.
Can the FAULT/SD pin be used as an input to force shutdown?
Yes - the FAULT/SD pin is bidirectional and CMOS-compatible at 3.3 V. Driving it low forces immediate soft shutdown of both high-side and low-side outputs. When released, the device resumes normal operation only after internal fault latching is cleared via FLT_CLR or power cycle, per the fault recovery sequence in the datasheet.
Does the IR22141SSPBF require external bootstrap diodes?
No - the IR22141SSPBF does not integrate bootstrap diodes. An external ultrafast diode (e.g., UF4007) must be placed between VB and VS to charge the bootstrap capacitor during low-side conduction. The device's 400 µA typical VBS quiescent current allows use of standard 0.1 µF ceramic capacitors in most medium-power designs.
How is desaturation detection calibrated for different IGBTs?
Desaturation detection threshold is fixed at 8.0 V on DSH/DSL pins. Calibration is achieved externally via resistor dividers from IGBT collector-to-emitter voltage (Vce) to DSH/DSL. For example, a 10 kΩ/100 kΩ divider scales 8 V at DSH to 88 V Vce trip point - values are selected based on IGBT saturation voltage and desired margin above nominal Vce(sat).
