Product details
Overview
IR2153STRPBF from Infineon Technologies is a self-oscillating 600V half-bridge gate driver IC with integrated 15.6V zener clamp on VCC, 1.2µs typical deadtime, and shutdown functionality triggered at 1/6th VCC on the CT pin. It drives high- and low-side N-channel MOSFETs in resonant LLC and SMPS inverters, supporting fixed-frequency operation up to 20.6kHz with RT/CT timing.
For engineers reviewing the IR2153STRPBF datasheet, IR2153STRPBF pinout, IR2153STRPBF application, or IR2153STRPBF equivalent, key selection criteria include its micropower startup current (75µA), ±1V UVLO hysteresis, 80/40ns rise/fall times, bootstrap diode integration (IR2153D variant), and latch immunity across all pins - critical for high-noise industrial power supplies.
Technical Context
The IR2153STRPBF implements a CMOS 555-style oscillator front-end driving dual output stages via high-voltage level-shifting circuitry. Its internal deadtime generator ensures consistent 0.75–1.65µs non-overlap between HO and LO outputs independent of supply variation.
Startup relies on micropower VCC current (≤150µA below UVLO) and stable oscillation requires external RT (10kΩ–100kΩ) and CT (330pF–10nF) components. The CT pin serves dual roles: timing ramp input and shutdown trigger at 2.1V threshold, enabling simple fault-handling without auxiliary logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET | 600V max - supports high-side switching in bridge topologies up to 600V bus voltage |
| Deadtime (typ.) | 1.2 µs - guarantees non-overlapping HO/LO drive to prevent shoot-through in half-bridge FETs |
| VCLAMP | 15.6V - internal zener limits VCC to safe operating range; requires ≥5mA supply current to maintain regulation |
| fosc (max) | 20.6 kHz - determined by RT=7.43kΩ & CT=1nF; sets upper bound for resonant converter switching frequency |
| UVLO Hysteresis | 1.0 V - improves noise immunity during brown-out conditions by widening turn-on/turn-off voltage gap |
| tr / tf | 80 / 40 ns - fast edge rates enable efficient MOSFET switching while maintaining EMI control |
| Shutdown Threshold | 2.1 V on CT pin - allows direct connection to microcontroller GPIO for fault-initiated disable |
Pinout & Package
IR2153STRPBF is supplied in an 8-lead SOIC package with standard surface-mount footprint and thermal resistance RthJA = 200°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VB | High-side floating supply | Connects to bootstrap capacitor anode; must sustain 600V offset relative to VS |
| HO | High-side gate driver output | Sinks/source up to 250mA to drive N-MOSFET gate; referenced to VS |
| VS | High-side floating return | Reference node for HO; must not swing >5V below ground due to latch risk |
| LO | Low-side gate driver output | In-phase with RT signal; drives N-MOSFET gate referenced to COM |
| VCC | Logic & gate drive supply | Powered via 10–15.6V source; internally clamped at 15.6V; draws ≤950µA quiescent current |
| RT | Oscillator timing resistor input | Sets frequency with CT; also provides feedback signal synchronized to LO output |
| CT | Oscillator timing capacitor input | Forms RC ramp for oscillator; doubles as shutdown input when pulled ≤2.1V |
| COM | Power & signal ground | Common reference for LO, VCC, RT, CT, and shutdown logic |
Key Features
| Feature | Design Value |
|---|---|
| True micropower startup | 75µA max ICC below UVLO enables reliable start-up from weak auxiliary supplies |
| Tighter initial deadtime control | 0.75–1.65µs range with low temperature coefficient ensures consistent timing over -40°C to +125°C |
| Integrated bootstrap diode (IR2153D) | 50ns typical forward recovery enables compact, low-loss bootstrap networks without external diodes |
| Enhanced latch immunity | Robust internal protection prevents false triggering during high dV/dt transients on VS or VB nodes |
| ESD protection on all leads | HBM ≥2kV on every pin eliminates need for external TVS in most board-level ESD environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar self-oscillating half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2153D | Successor product with improved propagation delay matching (±10ns), lower ICC (400µA typ.), and enhanced ESD rating (4kV HBM) | Same pinout and function; optimized for higher-efficiency 20–500kHz resonant converters | Preferred for new designs per Infineon recommendation; requires no layout change |
| IR2155STRPBF | Legacy predecessor with wider deadtime (1.5–2.5µs), no CT shutdown, and 1.5V UVLO hysteresis | Lacks programmable shutdown and tighter timing control; suitable only for legacy repair or cost-sensitive low-frequency (<15kHz) designs | Acceptable where design freeze prohibits component revision but not recommended for new projects |
Compared with IRS2153D, IR2153STRPBF offers proven reliability in mature 20kHz-class SMPS but lacks the tighter timing specs and lower power consumption needed for next-gen high-density converters; versus IR2155STRPBF, it delivers superior noise immunity and startup stability at minimal BOM impact.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The IR2153STRPBF specifies a maximum allowable dV/dt of ±50 V/ns on the VS node. Exceeding this rate risks latch-up due to parasitic thyristor activation in the high-side level shifter. Layout best practices include minimizing loop area between VS and COM, using low-inductance ceramic bootstrap capacitors, and avoiding sharp-edged gate drive waveforms that induce excessive ringing.
Can IR2153STRPBF drive IGBTs directly?
Yes - IR2153STRPBF can drive discrete IGBTs with gate charge ≤150nC and VGE threshold ≤5V, provided gate resistors limit peak current to <250mA and bootstrap voltage remains ≥12V. For high-power IGBT modules requiring >2A peak gate current or negative turn-off bias, an external gate driver stage is required before the IR2153STRPBF output.
Is the internal bootstrap diode present in IR2153STRPBF?
No - the internal 50ns bootstrap diode is exclusive to the IR2153D variant (PDIP only). The IR2153STRPBF (SOIC) does not integrate this diode; an external ultrafast diode (e.g., BAS21, trr ≤50ns) must be placed between VB and VS to charge the bootstrap capacitor during LO conduction.
How does the CT pin shutdown function interact with oscillator operation?
When CT voltage falls to ≤2.1V, the IR2153STRPBF disables both HO and LO outputs immediately (660ns propagation delay) while preserving internal oscillator state. Upon CT voltage rising above 2.4V, normal oscillation resumes with full deadtime control - no re-synchronization or phase reset is required, enabling seamless fault recovery in closed-loop systems.
