Product details
Overview
IR2153S 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 fluorescent lamp ballast circuits, supporting fixed-frequency operation up to 106kHz with RT/CT timing.
For engineers reviewing the IR2153S datasheet, IR2153S pinout, IR2153S application, or IR2153S equivalent, key selection criteria include its micropower startup current (75µA), ±1V UVLO hysteresis, 80/40ns rise/fall times, bootstrap diode integration (in IR2153D variant), and latch immunity across all pins under noisy industrial switching conditions.
Technical Context
The IR2153S implements a CMOS 555-style oscillator front-end with dual comparators (CT ramp thresholds at 4.0V and 8.0V) driving an RS latch and deadtime logic. Its high-voltage level-shifting circuit uses floating bootstrap architecture to drive HO referenced to VS, with internal 15.6V zener clamping protecting VCC from overvoltage during startup or transient events.
Deadtime is generated by fixed delay elements (0.75–1.65µs) between complementary HO/LO edges, independent of supply voltage or temperature due to low temperature coefficient design. The CT pin serves dual roles: oscillator timing node and shutdown input-pulling CT ≤2.4V disables both outputs via UV-mode detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 600V - supports high-side switching in offline AC-DC converters without external level-shifters |
| Deadtime (typ.) | 1.2 µs - prevents shoot-through in half-bridge power stages by ensuring non-overlapping HO/LO conduction |
| VCLAMP | 15.6V - internal zener limits VCC to safe operating range; requires ≥5mA supply current for stable clamping |
| fosc (max) | 106 kHz - set by RT=7.43kΩ & CT=1nF; enables compact magnetics in resonant SMPS designs |
| UVLO Hysteresis | 1.0 V - improves noise immunity during brown-out recovery by preventing oscillation near threshold |
| Startup ICC | 75 µA (max) - enables direct capacitor-charging startup from rectified AC without auxiliary winding |
| tr/tf | 80/40 ns - fast edge rates reduce switching losses while maintaining EMI control via controlled di/dt |
Pinout & Package
IR2153S is housed in an 8-lead PDIP package (01-3003-01), with creepage/clearance compliant for 600V isolation. Pin functions are electrically validated per Infineon PD60062 revP datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM | Signal ground reference | Common return for LO, RT, CT, and VCC; must be low-impedance path to avoid UVLO false triggering |
| VCC | Logic & gate drive supply | Powered via startup resistor or auxiliary winding; clamped at 15.6V to protect internal circuitry |
| RT | Oscillator timing resistor input | Sets frequency and duty cycle (48–52%); output in phase with LO for synchronous control |
| CT | Oscillator timing capacitor + shutdown input | Charged/discharged by internal current sources; ≤2.4V forces shutdown mode disabling HO/LO |
| LO | Low-side gate driver output | Drives N-MOSFET source-connected to COM; logic-level compatible with standard gate thresholds |
| HO | High-side gate driver output | Drives N-MOSFET source-connected to VS; referenced to floating VS node via bootstrap capacitor |
| VS | Floating supply return | Return path for high-side driver; must not swing >5V below COM to prevent latch-up |
| VB | Floating supply input | Connects to bootstrap capacitor top; supplies HO driver; offset up to 600V above COM |
Key Features
| Feature | Design Value |
|---|---|
| Tighter initial deadtime control | 0.75–1.65µs tolerance ensures consistent shoot-through margin across production lots and temperatures |
| True micropower startup | 75µA max ICC at UVLO threshold enables direct AC-line startup without auxiliary bias winding |
| Shutdown via CT pin | Single-pin disable function (≤2.4V) simplifies fault handling in lamp ignition or overcurrent protection |
| Lower di/dt gate drivers | Controlled edge rates reduce EMI generation and improve noise immunity in high-dV/dt environments |
| ESD protection on all leads | HBM ≥2kV rating protects against handling damage during PCB assembly and field service |

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 | Includes integrated 50ns bootstrap diode; SOIC-8 only; higher ICC quiescent current (500–950µA vs 75–150µA startup) | Better suited for space-constrained designs where discrete bootstrap diode placement is impractical | Select IRS2153D when board area is critical and bootstrap diode integration reduces BOM count |
| IR21531S | Same pinout; enhanced ESD rating (4kV HBM); tighter deadtime spec (0.9–1.5µs); identical UVLO and oscillator architecture | Preferred for automotive lighting modules requiring higher reliability and AEC-Q100 alignment | Choose IR21531S for new industrial or automotive designs needing improved robustness without layout change |
Compared with IR2153S, IRS2153D trades micropower startup for integrated bootstrap diode convenience, while IR21531S retains ultra-low startup current but adds ESD hardening and tighter deadtime-making it ideal for next-gen lighting and power tools where field reliability is critical.

FAQ
What is the minimum VCC startup voltage for reliable IR2153S operation?
The IR2153S begins functional operation once VCC rises above the rising UVLO threshold of 8.1V (min), with full gate drive capability established at 9.0V (typ). Startup current remains below 150µA until this threshold is crossed, enabling direct charging from high-value resistors across rectified AC lines without auxiliary windings.
Can IR2153S drive SiC MOSFETs directly?
IR2153S can drive SiC MOSFETs in half-bridge configurations if gate charge requirements fall within its 250mA peak output capability and if VGS thresholds (typically 3–5V) align with its VOH/VOL specs. However, its 80/40ns edge rates may require external gate resistors to limit di/dt and prevent parasitic oscillation in fast-switching SiC layouts.
How does the CT pin shutdown function interact with oscillator timing?
When CT voltage drops to ≤2.4V, the device enters shutdown mode: HO and LO outputs go low, oscillator stops, and ICC drops to <100µA. Timing resumes only after CT recharges above 4.0V (lower ramp threshold), ensuring clean restart without metastability-critical for lamp re-ignition or fault recovery sequences.
Is the internal 15.6V zener clamp sufficient for VCC regulation in all operating conditions?
The 15.6V zener clamp protects against overvoltage but is not a regulator: it requires ≥5mA continuous current into VCC to maintain clamping. If supply impedance is too high (e.g., large startup resistor), VCC may sag during heavy gate drive loads, causing UVLO dropout. A dedicated LDO or buffered supply is recommended for sustained high-frequency operation.
