Product details
Overview
IRS2509STRPBF from Infineon Technologies (formerly International Rectifier) is a 600V high-voltage, high-speed half-bridge gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (HO) and low-side (LO) outputs with matched 750 ns / 250 ns propagation delays, internal 530 ns dead-time, and 3.3 V/5 V/15 V logic-compatible inputs. It operates in HID electronic ballasts and resonant DC-DC converters where robust floating channel operation up to 600 V offset is required.
For engineers reviewing the IRS2509STRPBF datasheet, IRS2509STRPBF pinout, IRS2509STRPBF application, or IRS2509STRPBF equivalent, key selection criteria include high-side floating voltage tolerance (600 V), under-voltage lockout thresholds (8.2 V hysteresis), pulsed output current capability (120 mA HO / 250 mA LO), and integrated shoot-through prevention logic.
Technical Context
The IRS2509STRPBF integrates a proprietary HVIC process with latch-immune CMOS logic to support reliable high-side switching at up to 600 V VS–COM offset. Its dual-channel architecture provides in-phase high-side output relative to IN, with matched turn-on/off propagation delays (≤60 ns mismatch) and fixed internal dead-time (530 ns typical) between LO turn-off and HO turn-on.
It features independent UVLO on both VCC and VB supplies (8.2 V threshold with 0.7 V hysteresis), shutdown input (/SD) that forces both outputs to high-impedance state, and lower di/dt gate drive design to improve noise immunity during fast switching transitions in high dv/dt environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Floating Voltage (VS) | 600 V - enables direct driving of high-side N-MOSFET/IGBT in buck, half-bridge, or resonant topologies without external level-shifting. |
| HO/LO Propagation Delay | 750 ns / 250 ns typ. - ensures precise timing control for synchronous rectification and zero-voltage switching circuits. |
| Internal Dead-Time | 530 ns typ. - prevents shoot-through by guaranteeing minimum off-time between LO turn-off and HO turn-on. |
| Output Drive Current | 120 mA (HO source) / 250 mA (LO sink) - sufficient to charge/discharge 1 nF gate capacitance in <100 ns for typical power devices. |
| Logic Input Compatibility | 3.3 V / 5 V / 15 V CMOS/TTL - allows direct interface with microcontrollers, DSPs, and FPGA GPIO without level translation. |
| VCC & VB UVLO Threshold | 8.2 V with 0.7 V hysteresis - prevents erratic switching during brown-out conditions and ensures clean startup/shutdown sequencing. |
| ESD Rating | HBM Class 1C (±1000 V), MM Class B (±200 V) - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
IRS2509STRPBF is housed in an 8-lead SOIC (SOIC-8N) package with creepage/clearance optimized for 600 V isolation. The package is RoHS-compliant and rated MSL2 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Logic input control | Drives both HO and LO in phase; compatible with 3.3 V–15 V logic levels. |
| /SD | Shutdown enable | Active-low input; pulls both HO and LO to high-impedance when asserted. |
| VB | High-side floating supply | Provides bias for high-side driver stage; referenced to VS, not COM. |
| HO | High-side gate output | Drives N-channel MOSFET/IGBT gate referenced to VS; capable of sourcing 120 mA. |
| VS | High-side floating return | Return path for high-side channel; withstands −50 V transient to +600 V DC offset vs. COM. |
| VCC | Low-side & logic supply | Bias for low-side driver and logic core; 10–20 V operating range. |
| LO | Low-side gate output | Drives N-channel MOSFET/IGBT gate referenced to COM; sinks 250 mA. |
| COM | Low-side ground reference | Common return for VCC, LO, and logic inputs; isolated from VS by internal level shifter. |
Key Features
| Feature | Design Value |
|---|---|
| Matched propagation delay | ≤60 ns max difference between HO and LO turn-on/turn-off delays - critical for symmetrical PWM in resonant converters. |
| Integrated dead-time | Fixed 530 ns internal dead-time - eliminates need for external RC timing networks and reduces PCB footprint. |
| Negative transient tolerance | Withstands −50 V @ 50 ns on VS–COM - protects against parasitic ringing in hard-switched half-bridges. |
| Cross-conduction prevention | Dedicated logic block enforces non-overlapping HO/LO states - prevents shoot-through even during rapid IN transitions. |
| Lower di/dt gate drive | Controlled slew rate on HO/LO edges - reduces EMI generation and improves immunity to capacitive coupling in high-noise environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2109SPBF | Same SOIC-8 package; improved propagation delay matching (±10 ns vs. ±60 ns); higher peak output current (260 mA LO). | Recommended for new designs per manufacturer; supports higher-frequency resonant topologies requiring tighter timing control. | Select IRS2109SPBF when designing new systems needing enhanced timing precision and higher drive strength. |
| IR2110PBF | Higher VB rating (600 V same), but no internal dead-time; requires external dead-time circuitry; wider VCC range (10–20 V same). | Suitable for legacy designs where external timing control is already implemented; lacks integrated shoot-through protection logic. | Choose IR2110PBF only if existing layout accommodates external dead-time generation and timing flexibility is prioritized over integration. |
Compared with IRS2509STRPBF, IRS2109SPBF offers tighter delay matching and higher drive current for next-gen resonant converters, while IR2110PBF trades integration for configurability-making IRS2509STRPBF optimal for cost-sensitive HID ballasts where its fixed dead-time and proven reliability are sufficient.

FAQ
What is the maximum allowable negative transient on the VS pin?
The IRS2509STRPBF tolerates −50 V transients on the VS pin relative to COM, with pulse width ≤50 ns. This rating is guaranteed by design and supports reliable operation in hard-switched half-bridge configurations where parasitic ringing occurs during turn-off transitions.
Does IRS2509STRPBF require external bootstrap components?
No. IRS2509STRPBF does not use bootstrap charging; it relies on an isolated floating supply (VB) referenced to VS. A dedicated high-voltage DC-DC converter or charge pump must supply VB, unlike bootstrap-based drivers that depend on LO switching to recharge.
Can IRS2509STRPBF drive both MOSFETs and IGBTs?
Yes. Its 120 mA HO source and 250 mA LO sink currents, combined with 600 V floating capability and lower di/dt gate drive, support safe and efficient switching of both N-channel power MOSFETs and IGBTs in half-bridge configurations.
Is IRS2509STRPBF pin-compatible with IRS2109SPBF?
Yes. IRS2509STRPBF and IRS2109SPBF share identical SOIC-8 pinout, pin functions, and electrical interface. However, IRS2109SPBF improves propagation delay matching and adds enhanced ESD protection, making it a drop-in upgrade for new designs.
