Product details
Overview
IR25600SPBF from Infineon Technologies (formerly International Rectifier) is a dual low-side gate driver IC for power MOSFETs and IGBTs, featuring matched 85 ns / 65 ns turn-on/turn-off propagation delays, ±1.5 A peak output current per channel, and 6–20 V gate drive supply range. It operates in industrial motor drives and half-bridge inverters where precise timing synchronization between two low-side switches is required.
For engineers reviewing the IR25600SPBF datasheet, IR25600SPBF pinout, IR25600SPBF application, or IR25600SPBF equivalent, key selection criteria include propagation delay matching, output current capability under pulsed short-circuit conditions, logic-level input compatibility with CMOS/LSTTL, and SOIC-8 thermal performance at 125°C ambient.
Technical Context
The IR25600SPBF integrates two independent high-current buffer stages with latch-immune CMOS logic, enabling robust operation in noisy industrial environments. Each channel delivers 1.5 A sink/source current with rise/fall times of 15 ns / 10 ns (typ.) into 1000 pF load at 15 V supply.
Input logic thresholds are fixed at VIH ≥ 2.7 V and VIL ≤ 0.8 V, ensuring compatibility with standard digital controllers. Propagation delays are tightly matched (ΔtPD < 20 ns typ.) to minimize shoot-through risk in synchronous low-side configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO+/IO− | ±1.5 A peak pulsed output current per channel - sufficient to drive 10 nC gate charge MOSFETs at >100 kHz switching frequency |
| VOUT Range | 6–20 V gate drive supply - supports 12 V and 15 V industrial bus rails without external regulation |
| ton/toff (typ.) | 85 ns / 65 ns - enables precise dead-time control in complementary low-side pairs |
| VIH/VIL | 2.7 V / 0.8 V - direct interface with 3.3 V or 5 V microcontrollers without level-shifting |
| tr/tf (typ.) | 15 ns / 10 ns - reduces switching losses in fast-switching SiC and GaN half-bridges |
| RthJA (SOIC) | 200 °C/W - limits junction temperature rise to ≤90°C at 150 mW dissipation in still air |
Pinout & Package
IR25600SPBF is housed in an 8-lead SOIC (SO8N) package with exposed pad thermal enhancement. Pin 1 is marked by notch or dot; pins are numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INA) | Logic input A | In-phase control signal for OUTA; CMOS/LSTTL compatible, Schmitt-triggered |
| 2 (INB) | Logic input B | In-phase control signal for OUTB; independent of INA, no internal cross-talk |
| 3 (VS) | Gate drive supply | Primary power rail for both output buffers; decoupling capacitor required at pin |
| 4 (GND) | Power ground | Common return for VS, inputs, and outputs; must be low-inductance connection |
| 5 (OUTA) | Output A | Low-side gate driver output sourcing/sinking up to ±1.5 A; referenced to GND |
| 6 (OUTB) | Output B | Low-side gate driver output sourcing/sinking up to ±1.5 A; matched delay to OUTA |
| 7, 8 (NC) | No connect | Not internally bonded; must remain unconnected and un-biased |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27524ADR | Higher 4 A peak output, 13 ns rise time, but no propagation delay matching spec | Better for ultra-fast SiC/GaN; unsuitable where channel-to-channel timing skew must be <20 ns | Select when higher drive strength outweighs timing matching requirement |
| TC4427ACOA | Lower 1.2 A peak output, no guaranteed delay matching, wider 4.5–18 V supply range | Cost-optimized for 5 V systems; lacks tight delay spec needed for precision inverter legs | Select for 5 V logic interfaces where timing skew tolerance >50 ns |
Compared with UCC27524ADR and TC4427ACOA, the IR25600SPBF uniquely guarantees sub-20 ns inter-channel propagation delay matching-critical for shoot-through prevention in high-frequency inverter designs-while maintaining 1.5 A drive strength and 3.3 V logic compatibility.

FAQ
What is the maximum allowable supply voltage for IR25600SPBF?
The absolute maximum VS rating is 25 V, but recommended operating range is 6–20 V. Operation above 20 V risks exceeding safe operating area limits during transient conditions and may degrade long-term reliability. Thermal derating begins above 15 V due to increased quiescent current and power dissipation.
Does IR25600SPBF support 3.3 V logic inputs?
Yes - VIH is specified at ≥2.7 V and VIL at ≤0.8 V, making it fully compatible with 3.3 V CMOS logic without level shifting. Input hysteresis (≥0.5 V) further ensures noise immunity in electrically noisy motor drive environments.
Can IR25600SPBF drive SiC MOSFETs effectively?
Yes - its 1.5 A peak output current, 15 ns rise time, and 6–20 V adjustable gate drive range enable effective switching of common 10–20 nC SiC MOSFETs at frequencies up to 200 kHz, provided gate loop inductance is minimized and local decoupling is used.
Are pins 7 and 8 truly unused in the SOIC package?
Yes - pins 7 and 8 are designated NC (no connect) in the official datasheet and functional block diagram. They are not bonded internally and must remain unconnected and un-biased; routing traces or applying voltage to them may cause unpredictable behavior or damage.
