Product details
Overview
IRS2011PBF from Infineon Technologies (formerly International Rectifier) is a high- and low-side gate driver IC for N-channel MOSFETs in half-bridge configurations, featuring independent 1.0A source/sink output channels, 200V floating offset capability, matched 60ns propagation delays, and 3.3V/5V logic compatibility-used in motor drive inverters and DC-DC converters.
For engineers reviewing the IRS2011PBF datasheet, IRS2011PBF pinout, IRS2011PBF application, or IRS2011PBF equivalent, key selection criteria include high-side dV/dt immunity, dual-channel UVLO thresholds (8.2–9.7V), 20ns max delay matching, bootstrap-compatible VB/VS operation, and PDIP-8 thermal performance (125°C/W).
Technical Context
The IRS2011PBF integrates two independent gate drivers: a high-side channel with floating HVIC architecture tolerant to −5V to +200V VS offset and immune to >50V/ns dV/dt transients, and a low-side channel referenced to COM. Both channels use CMOS Schmitt-trigger inputs with internal pull-downs and share identical 10–20V supply ranges.
Propagation delays are tightly matched (≤20ns difference between HIN→HO and LIN→LO paths) to minimize shoot-through risk in high-frequency PWM switching. Undervoltage lockout (UVLO) operates independently per channel with hysteresis-VBS and VCC thresholds set at 8.2–9.7V with 0.8V hysteresis-ensuring robust start-up and fault recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET (max) | 200V - supports high-side operation up to 200V bus voltage in half-bridge topologies |
| IO+/IO− (typ) | 1.0A / 1.0A - delivers sufficient peak current to rapidly charge/discharge MOSFET gates with <40ns rise/fall times |
| ton/toff (typ) | 60ns / 60ns - enables stable operation at switching frequencies up to ~5 MHz before timing skew dominates |
| Delay Matching (max) | 20ns - ensures synchronous edge alignment between high- and low-side outputs to prevent cross-conduction |
| VIN Logic Compatibility | 3.3V & 5V CMOS/LSTTL - interfaces directly with microcontrollers, FPGAs, and PWM controllers without level-shifting |
| UVLO Thresholds | VBS/VCC: 8.2–9.7V with 0.8V hysteresis - prevents erratic switching during brown-out or bootstrap capacitor discharge |
| dV/dt Immunity | 50 V/ns - maintains correct logic state during fast high-side switching transients in noisy power stages |
Pinout & Package
IRS2011PBF is housed in an 8-lead PDIP package (0.300" wide), optimized for through-hole mounting and thermal dissipation in industrial motor drives. Pin assignments are validated per IRF datasheet Rev. A (Oct 2015).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN | High-side logic input | CMOS Schmitt-triggered; active-high, pulls down when unconnected; controls HO output phase |
| LIN | Low-side logic input | CMOS Schmitt-triggered; active-high, pulls down when unconnected; controls LO output phase |
| VB | High-side floating supply | Connects to bootstrap capacitor positive; supplies HO driver stage referenced to VS |
| HO | High-side gate drive output | Drives N-MOSFET gate; rated for 1.0A sink/source; referenced to VS |
| VS | High-side floating return | Source node of high-side MOSFET; serves as local ground reference for VB/HO circuitry |
| VCC | Low-side fixed supply | 10–20V supply for LO driver and logic; referenced to COM |
| LO | Low-side gate drive output | Drives N-MOSFET gate; rated for 1.0A sink/source; referenced to COM |
| COM | Low-side return | System ground reference for LIN, VCC, LO; must be connected to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with latch-immune HVIC | Enables reliable high-side operation up to 200V with no false triggering under rapid dV/dt stress |
| Matched propagation delay (≤20ns) | Reduces dead-time uncertainty in PWM control, critical for minimizing conduction loss in synchronous rectifiers |
| Independent UVLO per channel | Prevents partial drive activation-both HO and LO remain off until their respective supplies exceed 8.2V |
| 3.3V/5V logic compatible inputs | Eliminates need for external level shifters when interfacing with modern MCU GPIOs or isolated PWM generators |
| CMOS Schmitt-trigger inputs with pull-down | Ensures defined logic state during startup, reset, or open-circuit conditions-no external resistors required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high- and low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2110PBF | Higher 2.5A peak output, but slower 120ns typical propagation delay and no 3.3V logic support | Better suited for high-current IGBTs in lower-frequency (<100kHz) industrial inverters | Select when higher drive current outweighs need for tight delay matching or low-voltage logic interface |
| UCC27324DR | Single-supply, non-floating design; only low-side capable; 4A peak, 25ns delay | Requires external high-side solution (e.g., transformer or isolated gate driver) for half-bridge use | Choose for cost-sensitive, low-side-only applications where floating capability is unnecessary |
Compared with IR2110PBF and UCC27324DR, IRS2011PBF uniquely balances 1.0A drive strength, 200V offset, 3.3V logic compatibility, and ≤20ns delay matching-making it optimal for compact, high-frequency half-bridge designs where bootstrap simplicity and timing precision are critical.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IRS2011PBF is specified to tolerate up to 50 V/ns on the VS pin without false triggering or latch-up. This rating is verified under worst-case conditions with VB = VS = 200V and TA = 125°C. Layout practices-including short, low-inductance VS traces and localized decoupling near VB/VS-must be followed to maintain this immunity in production designs.
Can IRS2011PBF drive IGBTs directly?
Yes, IRS2011PBF can drive small- to medium-size IGBTs (up to ~30A rated) due to its 1.0A peak source/sink current and 200V offset rating. However, for larger IGBTs requiring >2A gate current or negative turn-off bias, an external gate resistor network or dedicated IGBT driver stage is recommended to ensure safe switching and Miller clamping.
Is a bootstrap diode required, and what type is recommended?
Yes, a fast-recovery or Schottky bootstrap diode is mandatory between VCC and VB to charge the bootstrap capacitor during low-side conduction. A 1N4148 is insufficient; recommended types include RB055LAM-40 (Schottky, 40V, 500mA) or MURS120 (ultrafast, 200V, 1A), selected for low forward voltage, fast reverse recovery, and adequate surge current rating.
Does IRS2011PBF support 3.3V-only logic without VCC ≥ 10V?
No. While logic inputs accept 3.3V high-level signals (VIH ≥ 2.5V at VCC = 10V), the VCC supply itself must be ≥10V for proper internal biasing and output drive strength. Operating VCC below 10V risks incomplete UVLO release, reduced IO+, and degraded propagation delay stability-even if HIN/LIN are driven with 3.3V logic levels.
