Product details
Overview
IRS21094SPBF from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed to control N-channel MOSFETs and IGBTs in high-side/low-side configurations. It features 600 V floating channel capability, 120 mA/250 mA peak output drive current, programmable deadtime (540 ns to 5 µs), and 3.3 V/5 V/15 V logic-compatible inputs. It is used in motor inverters, induction cooktops, and DC-DC converters requiring robust bootstrap operation.
For engineers reviewing the IRS21094SPBF datasheet, IRS21094SPBF pinout, IRS21094SPBF application, or IRS21094SPBF equivalent, key selection criteria include high-side voltage tolerance (600 V), matched propagation delay (≤70 ns), undervoltage lockout thresholds (8.2–9.8 V), logic ground separation (VSS), and programmable deadtime via external RDT resistor.
Technical Context
The IRS21094SPBF integrates a high-voltage level shifter with latch-immune CMOS technology to enable reliable operation at VS = −5 V to +600 V. Its dual-channel architecture provides independent high-side (HO) and low-side (LO) outputs with in-phase HO response to IN and cross-conduction prevention logic.
It implements internal 540 ns fixed deadtime between LO turn-off and HO turn-on, extendable to 5 µs using an external RDT resistor connected to the DT pin. The VSS pin provides isolated logic ground referenced to COM, enabling precise noise margin control in high-dV/dt environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Floating Voltage | 600 V - supports high-side switching up to 600 V bus voltage without breakdown |
| Output Drive Current | 120 mA / 250 mA - sufficient to rapidly charge/discharge gate capacitance of power MOSFETs up to ~1 nF |
| Propagation Delay (ton/toff) | 750 ns / 200 ns - enables >500 kHz PWM operation with tight timing control |
| Deadtime Range | 540 ns to 5 µs - prevents shoot-through in bridge topologies; adjustable via single RDT resistor |
| Logic Input Compatibility | 3.3 V, 5 V, 15 V - interoperable with microcontrollers, FPGAs, and analog comparators without level shifting |
| UVLO Thresholds | VCC/VBS: 7.4–9.8 V - ensures gate drive remains disabled until supply stabilizes, preventing partial turn-on |
| dV/dt Immunity | 50 V/ns - maintains correct logic state during fast high-side commutation transients |
Pinout & Package
IRS21094SPBF is housed in an 8-lead SOIC package with gull-wing leads, RoHS-compliant, rated for surface-mount reflow assembly. Thermal resistance RthJA is 200 °C/W under standard board-mounted conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Low-side and logic supply input | Provides 10–20 V bias for internal logic and LO driver; referenced to COM |
| 2 (IN) | Logic input for both HO and LO | In-phase with HO output; referenced to VSS (not COM); compatible with 3.3 V/5 V logic |
| 3 (SD) | Shutdown control input | Active-high; disables both HO and LO when driven ≥2.5 V above VSS |
| 4 (COM) | Low-side return and reference for LO | Power ground for low-side output stage and UVLO sensing; common return for load |
| 5 (VB) | High-side floating supply input | Connects to bootstrap capacitor; supplies HO driver stage referenced to VS |
| 6 (HO) | High-side gate drive output | Drives gate of high-side N-MOSFET/IGBT; floats with VS up to 600 V |
| 7 (VS) | High-side floating supply return | Source/emitter node of high-side switch; serves as local ground for HO stage |
| 8 (LO) | Low-side gate drive output | Drives gate of low-side N-MOSFET/IGBT; referenced to COM; complements IN signal |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with 600 V rating | Enables direct high-side drive in buck, half-bridge, and resonant topologies without external level shifters |
| Programmable deadtime (540 ns–5 µs) | Reduces risk of shoot-through across varying load, temperature, and MOSFET gate charge conditions |
| VSS-referenced logic ground | Isolates digital control domain from noisy power ground, improving noise immunity and timing stability |
| Matched propagation delay (≤70 ns) | Minimizes timing skew between HO and LO edges, critical for symmetrical PWM and ZVS operation |
| Lower di/dt gate driver stage | Slows gate edge rates intentionally to reduce EMI and improve robustness against parasitic ringing |

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 |
|---|---|---|---|
| IRS2109SPBF | No DT pin or VSS; fixed 540 ns deadtime; logic referenced to COM | Lacks programmable deadtime and isolated logic ground; suitable only for simpler, lower-noise designs | Select when deadtime tuning and noise isolation are not required, and cost sensitivity outweighs flexibility |
| IR2110PbF | Higher 2 A peak output current; no VSS pin; 10–20 V VCC range; 120 ns typical propagation delay | Designed for higher-power industrial inverters; lacks programmable deadtime and logic ground separation | Choose for high-current gate drive where faster switching and higher drive strength are prioritized over noise immunity |
Compared with IRS2109SPBF and IR2110PbF, the IRS21094SPBF uniquely combines programmable deadtime, VSS-referenced logic, and 600 V dV/dt immunity-making it optimal for noise-sensitive, variable-load resonant and inverter applications where timing precision and robustness are co-critical.

FAQ
What is the function of the VSS pin on IRS21094SPBF?
VSS is the dedicated logic ground reference for IN and SD inputs, electrically isolated from COM. It enables clean digital signaling in high-noise environments by decoupling control logic from power ground bounce, and must be tied to a quiet ground plane separate from COM unless system layout constraints require connection via low-inductance path.
Can IRS21094SPBF drive SiC MOSFETs?
Yes-its 120 mA/250 mA peak output current, 750 ns/200 ns propagation delays, and 600 V floating capability meet typical gate drive requirements for 650 V SiC MOSFETs. However, gate resistor selection must account for SiC's lower Qg and faster switching; layout must minimize loop inductance to avoid oscillation.
How is deadtime programmed on IRS21094SPBF?
Deadtime is set by connecting an external resistor (RDT) between the DT pin and VSS. With RDT = 0 Ω, deadtime is fixed at 540 ns; increasing RDT to 200 kΩ extends it to 5 µs. The relationship is linear per datasheet Figure 4, and RDT must be placed close to the DT pin with short traces to avoid noise coupling.
Does IRS21094SPBF require external bootstrap diode and capacitor?
Yes-a fast recovery bootstrap diode (e.g., 1N4148W or equivalent) and low-ESR ceramic capacitor (typically 0.1–1 µF, X7R) are mandatory between VB and VS. The capacitor replenishes charge lost during high-side conduction; insufficient capacitance causes VBS droop and UVLO triggering during sustained high-duty-cycle operation.
