Product details
Overview
IRS2011STRPBF 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 delay (max 20ns mismatch), and 10–20V gate drive supply range. It enables robust motor control and DC-DC converter topologies with dV/dt immune HVIC technology.
For engineers reviewing the IRS2011STRPBF datasheet, IRS2011STRPBF pinout, IRS2011STRPBF application, or IRS2011STRPBF equivalent, key selection criteria include bootstrap-compatible high-side operation up to 200V, 3.3V/5V logic compatibility, dual-channel undervoltage lockout (8.2–9.7V thresholds), and SOIC-8 thermal performance (RthJA = 200°C/W).
Technical Context
The IRS2011STRPBF integrates two independent gate drivers-high-side referenced to VS (floating) and low-side referenced to COM-each with CMOS Schmitt-trigger inputs, pull-down resistors, and matched propagation delays critical for synchronous switching. Its HVIC process ensures latch immunity and tolerance to negative transients up to 50 V/ns.
It operates with separate supplies: VB (10–20V) powers the high-side channel with internal 20V clamp, while VCC (10–20V) powers the low-side channel; both feature independent UVLO with hysteresis (±0.7V) and logic hold functionality across VS = –5V to +200V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET (max) | 200V - supports high-side N-MOSFET switching in buck, half-bridge, and motor drive topologies up to 200V bus voltage |
| IO+/IO− (typ) | 1.0A / 1.0A - delivers sufficient peak current to rapidly charge/discharge gate capacitance of medium-power MOSFETs |
| ton/toff (typ) | 60ns / 60ns - enables stable operation at switching frequencies >1 MHz with minimal dead-time uncertainty |
| Delay Matching (max) | 20ns - ensures precise timing alignment between high- and low-side outputs, reducing shoot-through risk |
| VIN Logic Compatibility | 3.3V and 5V CMOS/LSTTL - interfaces directly with microcontrollers, FPGAs, and PWM controllers without level-shifting |
| UVLO Thresholds | VBS/VCC: 8.2–9.7V (hysteresis ±0.7V) - prevents erratic gate driving during supply brown-out or startup |
| RthJA | 200°C/W (SOIC-8) - defines thermal derating limit under still-air conditions; requires PCB copper area for >0.625W continuous dissipation |
Pinout & Package
IRS2011STRPBF is housed in an 8-lead SOIC (SO8N) package with standard 1.27mm pitch, optimized for surface-mount assembly and thermal management via exposed pad (not present in base SOIC-8). Pin functions are electrically isolated between high-side (VB, HO, VS, HIN) and low-side (VCC, LO, COM, LIN) domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN | High-side logic input | CMOS Schmitt-triggered, active-high signal controlling HO output; includes internal pull-down for default-low safety state |
| LIN | Low-side logic input | CMOS Schmitt-triggered, active-high signal controlling LO output; includes internal pull-down for default-low safety state |
| VB | High-side floating supply | Bootstrap-supplied rail (10–20V) powering high-side driver stage; clamped internally at 20V |
| HO | High-side gate drive output | 1.0A source/sink output referenced to VS; drives N-MOSFET gate in high-side configuration |
| VS | High-side floating return | Reference node for high-side channel; withstands –5V to +200V offset relative to COM |
| VCC | Low-side fixed supply | 10–20V supply for low-side driver; independent UVLO and quiescent current (200–300μA) |
| LO | Low-side gate drive output | 1.0A source/sink output referenced to COM; drives N-MOSFET gate in low-side configuration |
| COM | Low-side ground reference | Common return for VCC, LO, and LIN; galvanically isolated from VS domain |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with dV/dt immunity | Withstands 50 V/ns transient on VS node-eliminates false triggering in noisy high-di/dt environments like motor drives |
| Matched propagation delay | ≤20ns difference between HIN→HO and LIN→LO paths-enables precise dead-time control without external calibration |
| Independent UVLO per channel | Dual 8.2–9.7V hysteresis thresholds prevent partial drive activation during asymmetric supply faults |
| Logic hold over full VS range | Maintains defined output state for VS = –5V to +200V-ensures safe shutdown during bootstrap capacitor discharge or negative flyback |
| CMOS Schmitt-trigger inputs | Provides noise margin >0.7V and eliminates metastability from slow-rising control signals in industrial EMI environments |

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 |
|---|---|---|---|
| IRS21844STRPBF | Higher drive current (2.0A), integrated bootstrap diode, same SOIC-8 package, but no logic hold below –5V VS | Preferred for higher-power inverters requiring faster gate charging; less suitable for deep bootstrap discharge scenarios | Select when gate Qg > 50nC and system requires built-in bootstrap diode; verify VS transient behavior during startup |
| LM5113MMX/NOPB | Lower VOFFSET (100V), 1.5A drive, adjustable dead time, requires external level shifter for high-side input | Better suited for lower-voltage DC-DC converters (<100V) where programmable timing is critical | Choose for designs needing configurable dead time and tighter propagation control (±5ns), but not for >100V high-side operation |
Compared with IRS21844STRPBF and LM5113MMX/NOPB, the IRS2011STRPBF uniquely balances 200V floating capability, logic hold down to –5V VS, and matched delay in a cost-optimized SOIC-8-making it optimal for mid-power motor drives and solar microinverters where bootstrap reliability and timing precision are jointly critical.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IRS2011STRPBF is rated for 50 V/ns on the VS pin under all operating conditions. This specification is verified per the Absolute Maximum Ratings table and ensures immunity to false triggering during fast-switching events in motor drives and inverters. Exceeding this rate may cause unintended high-side turn-on or latch-up, even with proper layout.
Can IRS2011STRPBF drive SiC or GaN MOSFETs?
Yes-the 1.0A peak output current, 25ns rise/15ns fall times, and 60ns propagation delay support common SiC and GaN devices with gate charges ≤35nC. However, layout must minimize parasitic inductance on HO/LO traces, and external gate resistors should be selected to manage dv/dt and ringing, as the IC lacks active Miller clamp or adaptive drive features.
Does the device require external bootstrap components?
Yes-a bootstrap diode and capacitor are required for high-side operation. The IRS2011STRPBF does not integrate a bootstrap diode. A fast-recovery or Schottky diode (e.g., 1N5819) and ≥0.1μF ceramic capacitor (X7R, 25V+) must be placed close to VB and VS pins to maintain stable VBS during duty cycles >95% and ensure reliable UVLO reset.
How does the logic hold function behave when VS goes negative?
When VS drops to –5V (relative to COM), the internal logic circuitry maintains the last valid HIN state at HO output until VS rises above –5V. This prevents uncontrolled high-side turn-off during inductive flyback or bootstrap capacitor discharge, enhancing system safety in motor brake or fault conditions without requiring external supervision circuitry.
