Product details
Overview
ICB2FL01GXUMA1 from Infineon Technologies is a second-generation smart ballast control IC for fluorescent lamp electronic ballasts, integrating discontinuous-mode PFC pre-converter control, high-voltage half-bridge inverter control, and 900V level-shifted gate drivers. It supports T5/T8 single- and multi-lamp topologies with resistor-programmable preheat time (up to 40 s), run frequency, and preheat frequency, and operates across −25°C to +125°C junction temperature.
For engineers reviewing the ICB2FL01GXUMA1 datasheet, ICB2FL01GXUMA1 pinout, ICB2FL01GXUMA1 application, or ICB2FL01GXUMA1 equivalent, key selection considerations include its integrated digital timers, filament break detection during startup and run mode, EOL/rectifier-effect monitoring, capacitive-load detection, and support for emergency lighting with skipped preheating on line interruption.
Technical Context
The ICB2FL01GXUMA1 implements a mixed-signal PFC controller operating in discontinuous conduction mode (DCM) with ZCD-based THD correction and adjustable current limiting. Its inverter section features dual lamp voltage sensing (LVS1/LVS2), low-side and high-side current sensing (LSCS/PFCCS), and adaptive dead-time control to prevent shoot-through in resonant half-bridge operation.
It embeds three independent digital timers-preheat (RTPH), run frequency (RFRUN), and preheat frequency (RFPH)-all set via external resistors. Protection logic includes latched shutdown on overcurrent (>1.6 V at LSCS for >500 ns), bus overvoltage, end-of-life (EOL1/EOL2), and capacitive-load detection with two distinct thresholds for idling and sub-resonant operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PFC Mode | Discontinuous Conduction Mode (DCM) only; enables zero-current switching and low THD without requiring critical conduction mode circuitry. |
| Junction Temp Range | −25°C to +125°C; ensures reliable operation in enclosed luminaires and high-ambient industrial lighting environments. |
| Lamp Voltage Sensing | Dual inputs (LVS1, LVS2); enables differential lamp arc voltage monitoring for precise EOL1 (overvoltage) and rectifier-effect (EOL2) detection. |
| Preheat Time Range | Resistor-programmable up to 40 seconds; supports slow-start requirements for long-life T5 lamps and cold ambient ignition. |
| Inverter Overcurrent Threshold | 1.6 V at LSCS for >500 ns; triggers latched shutdown to protect MOSFETs during short-circuit or failed lamp conditions. |
| High-Side Driver Rating | 900 V level-shifted output (HSGD); drives high-side MOSFET directly without external bootstrap or isolated supply in half-bridge topology. |
| Emergency Restart | Skips preheat phase upon brief AC line interruption (<100 ms); maintains lamp operation in emergency lighting systems without re-ignition delay. |
Pinout & Package
ICB2FL01GXUMA1 is housed in a PG-DSO-19-1 package - a 19-pin, thermally enhanced, surface-mount SOIC variant with extended creepage distance (Pin 16) for high-voltage fluorescent ballast isolation compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 LSCS | Low-side current sense input | Detects inverter low-side MOSFET source current for overcurrent protection and ignition slope control (205 mV/µs threshold). |
| 2 LSGD | Low-side gate driver output | Drives N-channel MOSFET gate with internal 0.5 A sink/source capability; referenced to GND (Pin 4). |
| 3 VCC | Main supply input | Accepts 11.5–16.5 V DC; powers internal logic, PFC, and low-side driver sections. |
| 4 GND | Low-side reference ground | Common return for VCC, LSCS, LSGD, and auxiliary circuits; separate from high-side ground (Pin 17). |
| 5 PFCGD | PFC gate driver output | Drives PFC switch gate (N-MOSFET) with 0.5 A drive strength; referenced to VCC. |
| 6 PFCCS | PFC current sense input | Monitors PFC inductor current via shunt; used for peak-current limiting and DCM boundary detection. |
| 7 PFCZCD | PFC zero-current detection | Identifies inductor current zero-crossing to enable optimal DCM switching timing and reduce switching losses. |
| 8 PFCVS | PFC bus voltage sense | Resistive divider input for PFC output voltage monitoring; enables OVP, 95%/75% bus regulation, and open-loop detection. |
| 9 RFRUN | Run frequency programming | Resistor-to-GND sets inverter operating frequency during normal lamp operation (e.g., 40–80 kHz). |
| 10 RFPH | Preheat frequency programming | Resistor-to-GND sets lower-frequency preheat oscillation (e.g., 25–50 kHz) to limit filament stress. |
| 11 RTPH | Preheat time programming | Resistor-to-GND sets preheat duration (up to 40 s); determines thermal ramp before ignition. |
| 12 RES | Lamp removal restart control | Pull-up enables automatic restart after lamp replacement; pull-down disables restart function. |
| 13 LVS1 / 14 LVS2 | Lamp voltage sensing inputs | Differential pair monitors lamp arc voltage for EOL1 (overvoltage), EOL2 (rectifier effect), and capacitive load detection. |
| 15 AUX | Auxiliary output | Open-drain output indicating active preheat or fault condition; usable for status LED or microcontroller interface. |
| 17 HSGND | High-side reference ground | Isolated return for high-side driver; must be connected to source of high-side MOSFET. |
| 18 HSVCC | High-side floating supply | Charged via bootstrap diode/capacitor; supplies HSGD stage (typically 10–14 V). |
| 19 HSGD | High-side gate driver output | Level-shifted 900 V capable driver for high-side MOSFET; synchronized with LSGD and adaptive dead-time control. |
| 20 NC | No connect | Not internally bonded; left unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| Digital timer programming | All timing functions (preheat, run, preheat frequency) set by external resistors-no external capacitors or crystals required. |
| Filament break detection | Separate detection of broken low-side and high-side filaments during startup and continuous run mode, preventing unsafe open-circuit operation. |
| Capacitive load detection | Two-stage detection (Idling vs. sub-resonant) avoids false shutdown during lamp aging or dimming, improving system robustness. |
| Ignition slope control | Monitors dI/dt at LSCS (205 mV/µs ±25 mV/µs); holds frequency constant until lamp strikes, enabling reliable ignition near choke saturation. |
| Customer test mode | Three configurable modes: skip preheat, hold preheat, or accelerate internal clock-reducing production test time without external equipment. |

FAQ
What is the maximum preheat time supported by ICB2FL01GXUMA1?
The ICB2FL01GXUMA1 supports preheat durations up to 40 seconds, set precisely via an external resistor on the RTPH pin. This value is digitally derived and validated across the full −25°C to +125°C junction temperature range, enabling reliable thermal ramping for long-life T5 lamps without external timing components.
Does ICB2FL01GXUMA1 require external bootstrap components for the high-side driver?
Yes-the HSGD stage requires an external bootstrap diode and capacitor connected between HSVCC (Pin 18) and HSGND (Pin 17). The IC does not integrate bootstrap charging circuitry; the external network must sustain ≥10 V at HSVCC during high-side conduction, with typical values being 100 nF ceramic and 1N4148 diode.
How does the IC detect end-of-life (EOL) in fluorescent lamps?
ICB2FL01GXUMA1 uses two independent methods: EOL1 detects sustained lamp arc voltage >350 V (via LVS1/LVS2 differential input), indicating electrode depletion; EOL2 identifies asymmetric current flow (rectifier effect) through lamp voltage waveform analysis during run mode, signaling irreversible cathode degradation.
Can ICB2FL01GXUMA1 drive MOSFETs directly without gate resistors?
No-external gate resistors (typically 10–47 Ω) are required on LSGD, HSGD, and PFCGD outputs to damp ringing, limit peak current, and ensure controlled turn-on/turn-off. The datasheet specifies maximum gate charge drive capability (0.5 A), but layout parasitics and MOSFET Qg necessitate series resistance for stability and EMI control.
