Product details
Overview
IR2153DPBF 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 106kHz with RT/CT timing.
For engineers reviewing the IR2153DPBF datasheet, IR2153DPBF pinout, IR2153DPBF application, or IR2153DPBF equivalent, key selection criteria include its micropower startup current (75µA), ±1V UVLO hysteresis, internal bootstrap diode (VF = 0.5V @ 250mA), latch immunity, and ESD protection on all pins.
Technical Context
The IR2153DPBF integrates a CMOS 555-style oscillator front-end with dual output drivers: HO (high-side, floating) and LO (low-side, referenced to COM). Its oscillator frequency is set by external RT (10kΩ–100kΩ) and CT (330pF–10nF), delivering 50% duty cycle with tight deadtime control (0.75–1.65µs).
It features true micropower startup (IQCCUV ≤ 150µA), constant pulse widths at startup, and enhanced noise immunity via reduced gate driver di/dt and improved level-shifting circuitry. The internal 15.6V zener clamp regulates VCC, requiring external current limiting per Note 1.
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 - prevents shoot-through by ensuring non-overlapping HO/LO drive pulses |
| VCLAMP | 15.6V - internal zener clamps VCC supply, requiring external current limiting to avoid overstress |
| fosc (max) | 106 kHz - determined by RT = 7.43kΩ and CT = 470pF; enables high-frequency resonant converter design |
| UVLO Hysteresis | 1.0 V - improves system stability during brown-out conditions by widening enable/disable thresholds |
| Bootstrap Diode VF | 0.5 V @ 250mA - integrated diode reduces BOM count and improves reliability vs. discrete bootstrap path |
| Startup Current | 75 µA (max) - enables direct capacitor-based start-up without auxiliary winding or bias supply |
Pinout & Package
IR2153DPBF is housed in an 8-lead PDIP package (0.300" wide), RoHS-compliant and lead-free (PbF). Pin assignments are identical for PDIP and SOIC variants per datasheet revision P.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VB | High-side floating supply rail | Connects to bootstrap capacitor positive; supplies HO driver stage referenced to VS |
| HO | High-side gate driver output | Drives gate of high-side N-MOSFET; floats with VS node up to 600V offset |
| VS | High-side floating supply return | Reference node for HO; must not swing >5V below ground inductively (Note 2) |
| LO | Low-side gate driver output | Drives gate of low-side N-MOSFET; referenced to COM; in-phase with RT signal |
| VCC | Logic & gate driver supply | Powered externally; internally clamped at 15.6V; requires current-limited source |
| RT | Oscillator timing resistor input | Sets oscillator frequency and duty cycle; also provides feedback for UVLO detection |
| CT | Oscillator timing capacitor input | Forms RC oscillator with RT; shutdown triggered when CT voltage drops to 2.1V (1/6 × VCC) |
| COM | Power and signal ground reference | Common return for LO, VCC, RT, CT, and logic circuits; isolated from VS node |
Key Features
| Feature | Design Value |
|---|---|
| Tighter initial deadtime control | 0.75–1.65µs range ensures robust shoot-through prevention across temperature and process variation |
| Low temperature coefficient deadtime | Stable timing over –40°C to +125°C junction range avoids frequency drift in thermal cycling |
| Shutdown feature on CT pin | Enables system-level fault response using simple resistor-divider to assert 2.1V threshold |
| Internal 50ns bootstrap diode (IR2153D) | Eliminates need for external diode; reduces layout complexity and parasitic inductance |
| ESD protection on all leads | HBM ≥ 2kV per JEDEC JESD22-A114 ensures robustness during handling and PCB assembly |

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 | Improved propagation delay matching, lower quiescent current (400µA), same pinout and function | Preferred for new designs per Infineon note; better thermal performance in SOIC-8 | Select IRS2153D for volume production where long-term availability and thermal margin are critical |
| IR21531PBF | Same architecture but lacks internal bootstrap diode; requires external diode and higher VCC headroom | Used where discrete bootstrap path is preferred for higher current or custom VF optimization | Choose IR21531PBF only if external diode integration is required for >500mA bootstrap current |
Compared with IR2153DPBF, IRS2153D offers lower power consumption and enhanced thermal specs while maintaining full pin and functional compatibility; IR21531PBF trades integrated diode convenience for greater external component flexibility in high-current bootstrap paths.

FAQ
What is the maximum allowable dV/dt on the VS node?
The absolute maximum allowable slew rate on the VS node is ±50 V/ns, as specified in the Absolute Maximum Ratings table. Exceeding this may cause false triggering or latch-up due to capacitive coupling into internal level-shift circuitry. Layout best practices include minimizing loop area between VS, HO, and bootstrap capacitor, and using local ceramic decoupling.
Can IR2153DPBF drive both N-channel and P-channel high-side MOSFETs?
IR2153DPBF is designed exclusively for N-channel high-side MOSFETs, as it provides a floating high-side driver referenced to VS with VB supply. It cannot directly drive P-channel devices, which require active-low gate control relative to source-no internal logic inversion or P-ch compatible output stage is provided.
How is the shutdown function implemented on the CT pin?
The CT pin shutdown activates when its voltage falls to 2.1V (typ.), corresponding to ~1/6th of nominal VCC. This is achieved by pulling CT low via an external resistor to COM or grounding CT. Once triggered, both HO and LO outputs disable immediately, with 660ns typical propagation delay, and remain off until VCC rises above UVLO threshold and CT recharges.
Is the internal bootstrap diode sufficient for continuous 1A gate drive?
No-the internal diode has VF = 0.5V at 250mA and is rated for pulsed bootstrap charging only. For continuous 1A peak gate current, external Schottky diode (e.g., 1N5819) and low-ESR bootstrap capacitor (≥100nF X7R) are required to maintain VB voltage and prevent under-voltage dropout during high-duty-cycle operation.
