Product details
Overview
IRS2106SPBF from Infineon Technologies is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (up to 600 V) and low-side outputs, 220 ns/200 ns propagation delays, 10 V–20 V gate drive supply range, and 3.3 V/5 V/15 V logic-compatible inputs. It enables half-bridge motor control in industrial inverters.
For engineers reviewing the IRS2106SPBF datasheet, IRS2106SPBF pinout, IRS2106SPBF application, or IRS2106SPBF equivalent, key selection criteria include bootstrap-capable floating channel operation, matched HS/LS propagation delay (<30 ns mismatch), undervoltage lockout on both channels, and SOIC-8 package thermal resistance (200 °C/W).
Technical Context
The IRS2106SPBF integrates a high-voltage level shifter and pulse filter to enable robust operation with dV/dt immunity up to 50 V/ns. Its floating channel supports VS offset from –5 V to +600 V while maintaining logic state integrity.
It uses latch-immune CMOS and HVIC monolithic construction, with separate logic ground (COM) and power return paths. The HO and LO outputs are in-phase with HIN and LIN inputs, and feature pulsed short-circuit current capability of 130 mA (HO) and 600 mA (LO).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max operating voltage | 600 V high-side floating supply (VB), enabling direct drive of 600 V-class power switches |
| Propagation delay (ton/toff) | 220 ns / 200 ns typical at 15 V bias - ensures precise timing control in high-frequency half-bridge switching |
| Delay matching (MT) | ≤30 ns max mismatch between HO and LO - critical for minimizing shoot-through risk |
| Logic input compatibility | 3.3 V, 5 V, and 15 V CMOS/LSTTL - supports mixed-voltage controller interfacing without level shifters |
| UVLO thresholds | VCC/VBS UV+ = 8.9 V, UV− = 8.2 V (0.7 V hysteresis) - prevents erratic output during brown-out conditions |
| Thermal resistance (RthJA) | 200 °C/W (SOIC-8) - defines maximum continuous power dissipation (0.625 W at TA ≤ 25 °C) |
Pinout & Package
IRS2106SPBF is housed in an 8-lead SOIC package with standard surface-mount footprint and 1.27 mm lead pitch. Pin assignments are fully validated per Infineon PD60246 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply rail | Fixed 10–20 V input powering internal logic and LO driver stage |
| HIN | High-side logic input | In-phase TTL/CMOS signal controlling HO output; referenced to COM |
| LIN | Low-side logic input | In-phase TTL/CMOS signal controlling LO output; referenced to COM |
| COM | Power and logic ground reference | Common return for LO, logic circuitry, and bootstrap capacitor discharge path |
| VB | High-side floating supply | Bootstrap node supplying gate drive for HO; must be ≥10 V above VS |
| HO | High-side gate drive output | Source-follower output driving N-MOSFET/IGBT gate; referenced to VS |
| VS | High-side floating return | Switching node connection point; defines floating domain reference for HO/VB |
| LO | Low-side gate drive output | Ground-referenced output driving N-MOSFET/IGBT gate; referenced to COM |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to 600 V without isolated supplies |
| dV/dt immune level shifting | Withstands 50 V/ns transients on VS node - suppresses false triggering in noisy inverter environments |
| Matched propagation delay | ≤30 ns HS/LS timing skew - reduces dead-time uncertainty and improves efficiency |
| Independent UVLO per channel | Prevents partial drive activation during under-supply conditions on either VCC or VB |
| Lower di/dt gate drive | Optimized output stage slew rate - minimizes EMI and improves noise immunity in compact PCB layouts |
Applications
| Motor Drive Inverters | Induction Heating Systems |
|---|---|
Use Scenario: 3-phase BLDC or PMSM motor control in HVAC compressors and industrial pumps. IC Role / Device Role / Timing Role: Dual-channel gate driver providing synchronized, shoot-through-protected HO/LO signals to half-bridge power stages. Use Value: 220/200 ns propagation delays and <30 ns matching ensure tight dead-time control, reducing conduction losses and thermal stress. | Use Scenario: Resonant tank switching in domestic and commercial induction cooktops. IC Role / Device Role / Timing Role: High-side/low-side driver for series-resonant LLC or half-bridge topologies operating at 20–100 kHz. Use Value: 600 V floating capability and dV/dt immunity allow reliable operation directly across resonant switch nodes with minimal layout filtering. |
| Solar Microinverters | UPS Half-Bridge Stages |
Use Scenario: DC–AC conversion stage in single-phase grid-tied microinverters for rooftop PV systems. IC Role / Device Role / Timing Role: Gate driver for high-efficiency synchronous rectification and PWM-controlled half-bridge switching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844SPBF | Includes programmable dead-time (540–5000 ns); higher peak output current (290 mA HO, 600 mA LO) | Required where precise external dead-time control is needed to accommodate varying gate charge or layout parasitics | Select when shoot-through margin must be actively tuned; not drop-in due to added SD pin and different pinout |
| IR2110SPBF | Wider VCC range (10–25 V); higher RthJA (220 °C/W SOIC-16); no logic ground (VSS) pin | Better suited for legacy 24 V control rails; requires larger PCB area due to 16-pin SOIC | Choose for compatibility with existing IR2110-based designs or where higher VCC headroom is required |
Compared with IRS2106SPBF, IRS21844SPBF adds design flexibility via programmable dead-time but increases BOM count and layout complexity, while IR2110SPBF trades package size and thermal performance for broader supply tolerance and field-proven reliability in high-power industrial systems.

FAQ
What is the minimum bootstrap capacitor value recommended for IRS2106SPBF?
Infineon specifies a minimum 0.1 µF ceramic bootstrap capacitor for typical 20 kHz switching with 1000 pF gate load. Larger values (≥0.22 µF) are advised for higher duty cycles or elevated temperatures to maintain VB ≥10 V above VS during HO conduction, preventing UVLO triggering.
Can IRS2106SPBF drive SiC MOSFETs?
Yes - its 10–20 V gate drive range, 290 mA peak HO source current, and fast 100 ns rise time meet typical SiC gate requirements. However, layout must minimize loop inductance, and external negative turn-off bias or active Miller clamp may be needed for full robustness beyond datasheet test conditions.
Is there a version of IRS2106 with integrated dead-time generation?
No - IRS2106SPBF lacks internal dead-time insertion. For integrated dead-time, consider IRS21844SPBF (programmable 540–5000 ns) or IRS21864SPBF (fixed 680 ns). IRS2106 relies on external MCU or logic to generate non-overlapping HIN/LIN signals.
What is the maximum allowable dV/dt on the VS pin?
The absolute maximum rated dV/dt on VS is 50 V/ns for the 8-lead PDIP package and 1.0 V/ns for the 8-lead SOIC package per PD60246. Exceeding this risks false level-shifter triggering; layout techniques like Kelvin VS routing and local decoupling are essential to stay within SOIC limits.
