Product details
Overview
IRS2103STRPBF from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed to independently control N-channel MOSFETs or IGBTs in high-side and low-side configurations. It supports up to 600 V floating channel operation, delivers ±130 mA / +270 mA peak output current, features 680 ns / 150 ns typical turn-on/turn-off propagation delay, and includes internal 520 ns deadtime for shoot-through prevention - used in motor inverters, SMPS half-bridge stages, and induction heating circuits.
For engineers reviewing the IRS2103STRPBF datasheet, IRS2103STRPBF pinout, IRS2103STRPBF application, or IRS2103STRPBF equivalent, key selection criteria include bootstrap-compatible floating channel design, 10–20 V gate drive supply range, 3.3 V/5 V/15 V logic compatibility, undervoltage lockout thresholds (8.2 V typ.), and matched propagation delays between channels.
Technical Context
The IRS2103STRPBF integrates a high-voltage level shifter and latch-immune CMOS logic to enable robust operation with VS offset up to 600 V. Its dual-channel architecture uses independent HVIC-based drivers: the high-side output (HO) is in-phase with HIN, while the low-side output (LO) is out-of-phase with LIN.
Internal cross-conduction prevention logic enforces fixed 520 ns deadtime between LO turn-off and HO turn-on, and vice versa. Propagation delays are tightly matched (≤60 ns skew), and dV/dt immunity ensures stable operation under fast transient conditions on the VS node.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max. Floating Voltage (VB) | 600 V - enables direct driving of high-side switches in 400 V DC bus applications like PFC and motor drives |
| Output Current (IO+/IO−) | 130 mA / 270 mA - sufficient to rapidly charge/discharge 1 nF gate capacitance in <100 ns |
| Propagation Delay (ton/toff) | 680 ns / 150 ns - ensures precise timing control in 100 kHz–500 kHz switching converters |
| Deadtime | 520 ns - prevents simultaneous conduction in half-bridge topologies without external timing circuitry |
| Logic Supply Range (VCC) | 10 V–20 V - supports direct connection to standard gate driver bias rails without regulation |
| UVLO Thresholds | VCCUV+ = 8.9 V, VCCUV− = 8.2 V - provides hysteresis to avoid oscillation during brown-out conditions |
| Input Logic Compatibility | 3.3 V, 5 V, and 15 V - allows interface with microcontrollers, DSPs, and isolated gate drivers |
Pinout & Package
IRS2103STRPBF is housed in an 8-lead SOIC package (RoHS-compliant, surface-mount), with thermal resistance RthJA = 200 °C/W and maximum junction temperature of 150 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides power for internal logic and low-side driver; must be decoupled near pin |
| HIN | High-side logic input | In-phase control signal for HO output; compatible with CMOS/LSTTL levels down to 3.3 V |
| LIN | Low-side logic input | Out-of-phase control signal for LO output; complements HIN for synchronous half-bridge operation |
| COM | Low-side return reference | Common ground for logic, low-side driver, and bootstrap capacitor discharge path |
| VB | High-side floating supply | Connects to bootstrap capacitor positive terminal; supplies high-side driver stage |
| HO | High-side gate drive output | Drives gate of high-side N-MOSFET/IGBT; referenced to VS, not COM |
| VS | High-side floating return | Switching node connection; serves as reference for HO and VB supply |
| LO | Low-side gate drive output | Drives gate of low-side N-MOSFET/IGBT; referenced to COM |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with bootstrap capability | Enables high-side drive without isolated supplies; supports VS transients up to 50 V/ns |
| Matched propagation delay | ≤60 ns skew between HO and LO paths ensures symmetrical switching timing |
| Integrated deadtime generation | Fixed 520 ns internal deadtime eliminates need for external timing components |
| dV/dt immune level-shifting | Prevents false triggering during fast VS node transitions in hard-switching topologies |
| 3.3 V–15 V logic compatibility | Direct interface with modern MCUs and digital controllers without level-shifting circuitry |

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 |
|---|---|---|---|
| IR2103S | Same functional spec, but PDIP package (not SOIC); higher RthJA (125 °C/W) and lower PD (1.0 W) | Suitable for prototyping or through-hole assembly; less suitable for high-density SMT production | Select IR2103S only when manual soldering or socket-based evaluation is required |
| IRS2003STRPBF | Higher IO+ (200 mA), wider VCC range (10–25 V), but no internal deadtime; requires external timing | Better for high-current gate drive where deadtime must be dynamically adjusted | Choose IRS2003STRPBF when adaptive deadtime control or >200 mA peak drive is mandatory |
Compared with IR2103S and IRS2003STRPBF, the IRS2103STRPBF uniquely balances SOIC manufacturability, integrated 520 ns deadtime, and 600 V capability - making it optimal for cost-sensitive, high-volume half-bridge designs where layout simplicity and timing reliability are critical.

FAQ
What is the recommended bootstrap capacitor value for IRS2103STRPBF?
A 0.1 µF ceramic capacitor rated ≥25 V is recommended between VB and VS pins. This value ensures sufficient charge replenishment during 100 kHz switching with 50% duty cycle, assuming typical gate charge of 50 nC per switch and 10 Ω gate resistor. Larger values (e.g., 0.22 µF) improve margin under high-duty-cycle or high-frequency operation.
Can IRS2103STRPBF drive IGBTs directly?
Yes - IRS2103STRPBF can directly drive IGBTs with gate-emitter threshold voltages ≤5 V and total gate charge ≤200 nC. Its 270 mA sink current and 130 mA source current support turn-on/turn-off times under 200 ns for 600 V/25 A IGBTs. External gate resistors must be selected to limit peak current within device ratings.
Does IRS2103STRPBF require external pull-down resistors on HIN and LIN inputs?
No - internal weak pull-downs are present on both HIN and LIN inputs, ensuring defined logic state during MCU reset or unpowered states. However, for noise-critical environments, 10 kΩ external pull-downs are recommended to reduce susceptibility to EMI-induced glitches on long traces.
How does the undervoltage lockout (UVLO) behave during startup?
IRS2103STRPBF activates UVLO when VCC falls below 8.2 V (negative-going threshold) and releases it at 8.9 V (positive-going). During startup, outputs remain disabled until VCC exceeds 8.9 V, preventing partial drive that could cause shoot-through. The 0.7 V hysteresis avoids oscillation during marginal supply conditions.
