Product details
Overview
ICB1FL02G from Infineon Technologies is a Smart Ballast Control IC for fluorescent lamp ballasts, integrating PFC preconverter (DCM), inverter control, and high-voltage half-bridge driver in a single PG-DSO-18-2 package. It delivers adjustable preheat time (0–2000 ms), run frequency (20–100 kHz), and end-of-life detection via dual ± lamp voltage thresholds. Used in T5 electronic ballasts for commercial lighting systems with multi-lamp topologies.
For engineers reviewing the ICB1FL02G datasheet, ICB1FL02G pinout, ICB1FL02G application, or ICB1FL02G equivalent, key selection considerations include its integrated PFC zero-current detection (PFCZCD), dual lamp voltage sense inputs (LVS1/LVS2), self-adapting ignition time (40–235 ms), resistor-programmable timing parameters, and built-in protection against capacitive-mode operation and rectifier effect.
Technical Context
The ICB1FL02G implements a two-stage fluorescent ballast controller: a discontinuous conduction mode (DCM) PFC preconverter with internal compensation and zero-current detection (PFCZCD), and an inverter stage with digital-analog hybrid control for preheat, ignition, and run modes. It supports critical conduction mode (CritCM) under medium load and DCM under light load.
Its architecture includes dedicated high-side (HSGD/HSVCC/HSGND) and low-side (LSGD/LSCS) gate drivers with asymmetric slew rates (220 ns rise / <50 ns fall), dual lamp voltage sensing (LVS1/LVS2) for EOL and rectifier-effect detection, and resistor-based configuration of preheat time (RTPH), preheat frequency (RFPH), and run frequency (RFRUN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PFC Mode | Discontinuous Conduction Mode (DCM) with CritCM transition; enables stable power factor correction without external loop compensation. |
| Run Frequency Range | 20 kHz to 100 kHz, set by resistor on RFRUN pin; avoids audible noise and ensures efficient lamp operation. |
| Preheat Time Range | 0–2000 ms, adjusted via RTPH resistor; prevents electrode sputtering and extends lamp life. |
| Lamp Voltage Sensing | Dual inputs (LVS1/LVS2); enables differential detection of end-of-life (± threshold) and rectifier effect (amplitude ratio). |
| Gate Drive Asymmetry | 220 ns turn-on / <50 ns turn-off; reduces EMI during turn-on while ensuring fast fault shutdown. |
| Overcurrent Protection | Two-level LSCS threshold: 0.8 V (frequency step-up during ignition), 1.6 V (latched shutdown); eliminates need for external comparator. |
| Supply Voltage Range | VCC: 10.5–17.5 V with UVLO; HSVCC: rated for 12 V high-side supply; supports direct bootstrap or isolated supply. |
Pinout & Package
ICB1FL02G is housed in a PG-DSO-18-2 surface-mount package (300 mil width), halogen-free and RoHS-compliant, with exposed thermal pad for enhanced power dissipation in ballast PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LSCS (Pin 1) | Inverter low-side current sense | Detects MOSFET source current for overcurrent protection; dual-threshold (0.8 V/1.6 V) enables adaptive ignition and latched shutdown. |
| LSGD (Pin 2) | Inverter low-side gate drive | Drives low-side MOSFET with controlled 220 ns rise time; active-low during UVLO; 11 V max output limits gate stress. |
| VCC (Pin 3) | Controller supply input | 14 V turn-on / 10.5 V UVLO threshold; internal 16 V zener clamp protects logic section under transient overvoltage. |
| GND (Pin 4) | Signal ground reference | Common return for VCC, sense inputs, and low-side drivers; must be low-inductance connection to minimize noise coupling. |
| PFCGD (Pin 5) | PFC MOSFET gate drive | Controls boost switch with soft turn-on; 10 Ω recommended series resistor shifts gate discharge loss externally. |
| PFCCS (Pin 6) | PFC current sense | 1 V overcurrent threshold with 260 ns blanking; disables PFC gate until zero-current detection (PFCZCD) confirms safe restart. |
| PFCZCD (Pin 7) | PFC zero-current detector | Hysteresis thresholds (0.5 V/1.5 V) detect inductor current zero-crossing; enables variable-frequency DCM/CritCM operation. |
| PFCVS (Pin 8) | PFC bus voltage sense | Resistive divider input referenced to 2.5 V internal bandgap; monitors 15% undervoltage, 73% nominal, and 109% overvoltage. |
| RFRUN (Pin 9) | Run frequency programming | Resistor-to-ground sets inverter operating frequency (20–100 kHz); enables precise acoustic noise management. |
| RFPH (Pin 10) | Preheat frequency programming | Resistor-to-ground (with RFRUN) sets preheat frequency; ensures optimal electrode heating before ignition. |
| RTPH (Pin 11) | Preheat time programming | Resistor-to-ground sets preheat duration (0–2000 ms); prevents premature lamp strike and cathode damage. |
| RES (Pin 12) | Lamp removal restart enable | Active-low input; initiates automatic restart sequence after lamp replacement in multi-lamp systems. |
| LVS1 / LVS2 (Pins 13–14) | Lamp voltage sensing pair | Differential inputs for EOL detection (± voltage thresholds) and rectifier-effect identification (amplitude ratio analysis). |
| HSGD (Pin 19) | Inverter high-side gate drive | Level-shifted output for high-side MOSFET; 1800 ns dead time vs. LSGD prevents shoot-through in half-bridge topology. |
| HSVCC / HSGND (Pins 18/17) | High-side floating supply | Supports bootstrap or isolated high-side supply; HSVCC rated for 12 V, HSGND serves as local return for high-side logic. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PFC compensation | Eliminates external Type II/III compensation network; reduces BOM count and layout sensitivity in DCM boost designs. |
| Self-adapting ignition time | Automatically adjusts from 40 ms to 235 ms based on lamp characteristics; ensures reliable cold-start without manual tuning. |
| Capacitive mode detection | Identifies unsafe resonant operation in lamp circuits using phase and amplitude analysis of LVS1/LVS2 signals. |
| End-of-life (EOL) detection | Triggers shutdown when lamp voltage asymmetry exceeds ± thresholds; prevents hazardous open-circuit or arc conditions. |
| Rectifier effect detection | Monitors ratio of positive/negative lamp voltage amplitudes; flags degraded electrodes before catastrophic failure. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2166D | Single-chip solution with integrated PFC + half-bridge driver; lacks dual LVS inputs and rectifier-effect detection logic. | Supports basic EOL but not multi-lamp rectifier-effect isolation; limited to single-lamp topologies. | Choose for cost-sensitive single-lamp designs where lamp health diagnostics beyond basic EOL are not required. |
| OB2263 | Standalone PFC controller + separate inverter IC; requires external zero-current detection circuit and dual lamp sense amplifiers. | Higher component count and layout complexity; no integrated capacitive-mode or rectifier-effect detection. | Choose only when legacy design reuse or discrete PFC/inverter optimization outweighs integration benefits. |

FAQ
What is the function of the RES pin (Pin 12) in ICB1FL02G?
The RES (Restart after Lamp Removal) pin is an active-low input that initiates an automatic restart sequence when pulled low-typically via external circuitry detecting lamp disconnection. It enables hot-swap capability in multi-lamp ballasts, allowing one lamp to be replaced without powering down the entire fixture. The IC resets internal state, re-executes preheat, and attempts reignition only for the affected lamp branch, preserving operation of remaining lamps.
How does ICB1FL02G detect rectifier effect in fluorescent lamps?
ICB1FL02G detects rectifier effect by analyzing the amplitude ratio between the positive and negative half-cycles of the lamp voltage sensed differentially across LVS1 and LVS2. When electrode emission degrades asymmetrically, this ratio deviates significantly from unity. The IC compares the ratio against an internal threshold and triggers protective shutdown if exceeded-preventing unstable arc operation and potential lamp explosion.
Can ICB1FL02G operate with 277 V AC mains input?
Yes-ICB1FL02G supports universal AC input from 90 V to 270 V RMS, validated per its absolute maximum ratings and functional specifications. Its PFCVS input monitors intermediate bus voltage up to 109% of nominal (e.g., 450 V DC for 400 V nominal), and internal clamping (6.3 V/−2.9 V on PFCZCD) ensures robust zero-current detection even under high-line transients typical in 277 V commercial installations.
What is the purpose of the dual-threshold overcurrent detection on LSCS?
The LSCS pin features two distinct overcurrent thresholds: 0.8 V (non-latching, >250 ns) triggers progressive frequency reduction during ignition to limit stress, while 1.6 V (>400 ns) causes immediate latched shutdown in all modes. This dual-level scheme prevents nuisance tripping during normal ignition current peaks while ensuring fail-safe protection against sustained short-circuit or MOSFET failure in the inverter leg.
