Product details
Overview
IRS2011SPBF from Infineon Technologies (formerly International Rectifier) is a high- and low-side gate driver IC designed to independently control N-channel MOSFETs in half-bridge configurations. It features 200V offset voltage tolerance, matched 60ns typical propagation delays (HIN/LIN), ±1.0A peak output current per channel, and 10–20V gate drive supply range-enabling robust motor drive and DC-DC converter applications.
For engineers reviewing the IRS2011SPBF datasheet, IRS2011SPBF pinout, IRS2011SPBF application, or IRS2011SPBF equivalent, key selection criteria include floating channel dV/dt immunity, 3.3V/5V logic compatibility, independent UVLO per channel, and SOIC-8 package thermal performance at 125°C ambient.
Technical Context
The IRS2011SPBF integrates two independent gate drivers: a high-side channel with floating HVIC architecture referenced to VS, and a low-side channel referenced to COM. Its bootstrap-compatible high-side driver supports up to 200V offset and withstands −5V to +200V VS transients without false triggering.
Both channels use CMOS Schmitt-triggered inputs with internal pull-downs, 8.3–9.7V UVLO thresholds (hysteresis ~0.8V), and matched propagation delay ≤20ns between HIN→HO and LIN→LO paths-critical for minimizing shoot-through risk in high-frequency switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET (max) | 200 V - Maximum allowable voltage difference between VS and COM, enabling direct high-side drive of 200V bus systems |
| IO+/IO− (typ) | ±1.0 A - Peak pulsed output current per channel, sufficient to rapidly charge/discharge 1000pF gate loads in <40ns |
| ton/toff (typ) | 60 ns - Propagation delay from input to output edge under 15V bias and 1000pF load, supporting >5 MHz PWM operation |
| Delay Matching (max) | 20 ns - Maximum absolute difference between HIN→HO and LIN→LO delays, ensuring precise dead-time control |
| VIN Logic Compatibility | 3.3 V / 5 V - Guaranteed VIH ≥2.5V and VIL ≤0.7V across full VCC range (10–20V), eliminating level-shifter requirements |
| UVLO Thresholds | 8.3–9.7 V (rising), 7.5–8.9 V (falling) - Hysteresis protects against oscillation during supply ramp-up/down in noisy industrial environments |
| dV/dt Immunity | 50 V/ns - Tolerance to fast transient voltage spikes on VS node, preventing false turn-on in high-di/dt motor drives |
Pinout & Package
IRS2011SPBF is housed in an 8-lead SOIC (SO8N) package with standard 1.27 mm pitch, rated for 125°C ambient operation and 200°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN | High-side logic input | CMOS/LSTTL-compatible active-high signal controlling HO output; internal pull-down holds low during power-up |
| LIN | Low-side logic input | Active-high input for LO output; electrically isolated from HIN path to prevent cross-talk |
| VB | High-side floating supply | Bootstrap capacitor connection point; supplies HO driver stage referenced to VS |
| HO | High-side gate drive output | Source-follower configured output driving N-MOSFET gate; capable of sourcing/sinking 1.0A peak |
| VS | High-side floating return | Reference node for VB and HO; tracks switching node voltage up to 200V offset from COM |
| VCC | Low-side fixed supply | 10–20V supply for LO driver and logic core; independent of VB/VS domain |
| LO | Low-side gate drive output | Ground-referenced output driving N-MOSFET gate; matched timing with HO for synchronous control |
| COM | Low-side ground reference | Common return for VCC, LO, LIN, and logic core; galvanically isolated from VS domain |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with latch-immune HVIC | Enables reliable high-side drive at 200V offset without external level shifters or protection circuitry |
| Matched propagation delay ≤20ns | Reduces need for external dead-time insertion, simplifying gate timing in half-bridge inverters |
| Independent UVLO per channel | Prevents partial drive activation during brown-out conditions-HO and LO disable separately if VB or VCC drops below threshold |
| 3.3V/5V logic compatible inputs | Direct interface with microcontrollers and FPGA I/O without level translation, reducing BOM count |
| dV/dt immune design | Withstands 50 V/ns transients on VS node, eliminating false triggering in high-speed motor commutation |
Applications
| Brushless DC Motor Drive | Industrial DC-DC Converters |

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 500V offset rating but slower 120ns typical propagation delay; no 3.3V logic support | Better suited for 400V+ industrial inverters where speed is secondary to voltage margin | Select when >200V offset is required and 3.3V MCU interface is not used |
| UCC27211D | 600V offset, 1.8A peak drive, but single-supply (no floating VB/VS); requires external level shifter for high-side | Optimized for high-current, high-voltage synchronous buck converters with integrated level-shift architecture | Choose when higher peak current and tighter layout control outweigh bootstrap complexity |
Compared with IR2110PbF and UCC27211D, IRS2011SPBF uniquely balances 200V offset, 60ns speed, 3.3V logic compatibility, and self-contained bootstrap operation-making it optimal for cost-sensitive, space-constrained 48V–100V motor and converter designs.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IRS2011SPBF is specified to tolerate up to 50 V/ns on the VS pin without false triggering. This immunity is achieved through proprietary latch-immune HVIC technology and internal noise filtering, making it suitable for high-di/dt motor phase-leg switching where rapid voltage transitions occur across the high-side source node.
Can IRS2011SPBF drive both high-side and low-side N-MOSFETs without external level shifters?
Yes-the IRS2011SPBF integrates a floating high-side channel with bootstrap capability (VB/VS pins) and a ground-referenced low-side channel (VCC/COM pins), enabling direct drive of two N-MOSFETs in a half-bridge without external level-shifting components. Its 200V offset rating supports common 48V–100V bus applications.
Does IRS2011SPBF require separate undervoltage lockout for each channel?
Yes-each channel has independent UVLO circuitry: VBSUV+ (8.3–9.7V) monitors the high-side supply (VB–VS), and VCCUV+ (8.3–9.7V) monitors the low-side supply (VCC). Both feature hysteresis (~0.8V) and disable their respective outputs (HO or LO) when supply drops below the falling threshold, preventing partial drive states.
What is the thermal resistance (RthJA) of the SOIC-8 package?
The IRS2011SPBF in SO8N package has a junction-to-ambient thermal resistance (RthJA) of 200°C/W under standard JEDEC PCB mounting conditions (2-layer board, 1 in² copper pad). This value assumes still air convection and defines the maximum power dissipation (0.625W at 25°C ambient) before junction temperature exceeds 150°C.
