Product details
Overview
IRS2106PBF from Infineon Technologies is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (HO) and low-side (LO) outputs referenced to floating (VS) and common (COM) grounds respectively. It supports up to 600 V bridge operation, delivers 220 ns/200 ns typical turn-on/turn-off propagation delays, operates with 10–20 V VCC supply, and maintains logic compatibility down to 3.3 V - used in half-bridge motor drives and SMPS inverters.
For engineers reviewing the IRS2106PBF datasheet, IRS2106PBF pinout, IRS2106PBF application, or IRS2106PBF equivalent, key selection criteria include bootstrap-capable high-side drive capability, matched propagation delay (<30 ns skew), undervoltage lockout on both channels, dV/dt immunity up to 50 V/ns, and 8-pin PDIP package thermal performance under industrial ambient conditions.
Technical Context
The IRS2106PBF integrates a high-voltage level shifter and pulse generator for the high-side channel, enabling operation with VS up to +600 V relative to COM. Its internal UV detection circuit triggers lockout when VCC or VB falls below 7.4–9.8 V thresholds, with hysteresis of 0.3–0.7 V.
Logic inputs HIN and LIN are CMOS/LSTTL-compatible and drive outputs in phase; no internal dead-time generation is present - timing control is external. The device uses latch-immune HVIC technology and features separate logic ground (VSS) only in IRS21064 variants; IRS2106PBF references all logic to COM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max operating voltage | 600 V high-side offset (VB–VS), enabling direct drive of high-voltage half-bridges |
| Propagation delay (ton/toff) | 220 ns / 200 ns typical at 15 V, ensuring precise synchronous switching in PWM systems |
| Delay matching (MT) | ≤30 ns max skew between HO and LO edges, critical for minimizing shoot-through risk |
| VCC supply range | 10–20 V, supporting standard gate drive rail designs without external regulation |
| Logic input compatibility | 3.3 V, 5 V, and 15 V logic levels accepted - simplifies interface with MCU/FPGA GPIO |
| dV/dt immunity | 50 V/ns (PDIP), preventing false triggering during fast high-side switching transients |
| UVLO thresholds | VCCUV+ = 8.0–9.8 V, VCCUV− = 7.4–9.0 V, with 0.3–0.7 V hysteresis for stable restart |
Pinout & Package
IRS2106PBF is housed in an 8-lead PDIP package (0.3 inch width) with through-hole mounting and JEDEC MS-001AC compliance. Thermal resistance RthJA is 200 °C/W, and maximum power dissipation is 0.625 W at TA ≤ +25 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides power for internal logic and low-side driver stage; must be decoupled near pin |
| HIN | High-side logic input | In-phase control signal for HO output; referenced to COM, not VSS |
| LIN | Low-side logic input | In-phase control signal for LO output; referenced to COM |
| COM | Power and logic ground reference | Common return for LO, logic, and bootstrap capacitor discharge path |
| VB | High-side floating supply input | Connects to bootstrap capacitor top node; supplies high-side driver stage |
| HO | High-side gate drive output | Drives N-MOSFET/IGBT gate in high-side configuration; floats with VS |
| VS | High-side floating supply return | Source/emitter node of high-side switch; defines floating ground for HO stage |
| LO | Low-side gate drive output | Drives N-MOSFET/IGBT gate in low-side configuration; referenced to COM |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to +600 V VS–COM, eliminating need for isolated supplies |
| Matched propagation delay | ≤30 ns skew between HO and LO ensures tight timing alignment for complementary PWM |
| Undervoltage lockout (UVLO) | Dual-channel protection with independent thresholds prevents partial drive during brownout |
| Logic-level flexibility | 3.3 V/5 V/15 V compatible inputs reduce need for level-shifting circuitry |
| dV/dt noise immunity | 50 V/ns tolerance on VS node avoids false turn-on during high di/dt commutation events |

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 |
|---|---|---|---|
| IRS2104PBF | Single-input (IN/SD), no LIN/HIN separation; lacks VSS pin; lower VCCUV threshold (6.5 V) | Suitable for simpler single-input half-bridge control; not for independent PWM channel routing | Select when system uses single PWM + shutdown instead of dual independent inputs |
| IR2110PBF | Higher drive current (2A peak), wider VCC range (10–20 V), but larger 14-pin PDIP package and higher quiescent current | Better suited for high-current IGBTs requiring faster gate charging; less optimal for space-constrained PCBs | Select when >1 A peak gate current or enhanced thermal margin is required over compact layout priority |
Compared with IRS2104PBF, IRS2106PBF provides true independent HIN/LIN control and tighter delay matching; versus IR2110PBF, it offers smaller footprint and lower IQ but reduced peak drive strength - choice depends on gate load, layout area, and control architecture.

FAQ
Can IRS2106PBF drive IGBTs directly without external components?
Yes - IRS2106PBF delivers up to 290 mA high-side and 600 mA low-side pulsed output current, sufficient to drive medium-power IGBTs (e.g., 50 A/600 V) with gate charge ≤150 nC. No external boost or level-shift circuitry is needed, though proper bootstrap capacitor sizing (≥0.1 µF ceramic + bulk electrolytic) and gate resistor selection remain essential for EMI and switching loss control.
What is the minimum recommended bootstrap capacitor value for IRS2106PBF?
The minimum recommended bootstrap capacitor is 0.1 µF X7R ceramic placed adjacent to VB and VS pins, supplemented by a 10 µF–47 µF electrolytic capacitor on the VCC rail. This ensures sufficient charge replenishment during continuous high-side conduction at 50% duty cycle and 100 kHz switching, preventing VB droop below UVLO threshold under worst-case load and temperature conditions.
Does IRS2106PBF require a separate logic ground (VSS) connection?
No - IRS2106PBF references all logic inputs (HIN, LIN) and the COM pin as the sole ground reference; VSS is exclusive to the IRS21064 variant. Connecting VSS on IRS2106PBF is incorrect and may cause malfunction. The device's logic and power grounds are unified at COM, simplifying PCB layout for single-ground systems.
How does IRS2106PBF handle negative voltage transients on the VS pin?
IRS2106PBF tolerates VS transients down to –5 V relative to COM, verified per absolute maximum ratings. Its level-shifter design incorporates dV/dt immune circuitry that suppresses false triggering during fast negative excursions - critical during inductive load freewheeling or shoot-through recovery. This allows reliable operation in hard-switched topologies without additional clamping diodes.
