Product details
Overview
ICB2FL02GXUMA2 from Infineon Technologies is a 2nd-generation smart ballast control IC for fluorescent lamp inverters, integrating discontinuous-mode PFC, high-voltage half-bridge driver (900 V), and digital timers up to 40 s. It supports T5/T8 single- and multi-lamp ballasts with current-mode preheating, EOL/rectifier-effect detection, and emergency lighting restart logic. Key confirmed parameters: 900 V half-bridge drive capability, ±25 mV/µs slope sensitivity at LSCS pin, 0.8 V overcurrent threshold, 500 ns fault latch delay, and RoHS-compliant PG-DSO-19-1 package.
For engineers reviewing the ICB2FL02GXUMA2 datasheet, ICB2FL02GXUMA2 pinout, ICB2FL02GXUMA2 application, or ICB2FL02GXUMA2 equivalent, this page delivers verified functional roles per pin, real-world protection behaviors (e.g., latched shutdown on >500 ns overcurrent), dimming-specific detection thresholds, and validated alternative controllers for fluorescent ballast redesigns - all grounded in Infineon's V1.2 preliminary datasheet and official package outline.
Technical Context
The ICB2FL02GXUMA2 implements a mixed-signal PFC architecture supporting DCM operation across 0–100% load range, with dedicated THD correction via ZCD signal and optional DCM-specific compensation. Its inverter section uses dual lamp voltage sense inputs (LVS1/LVS2) to distinguish open-filament HS vs. LS faults and detect capacitive-load operation below resonance.
Control timing is fully resistor-programmable: RFRUN sets run frequency, RFPH sets preheat frequency, and RTPH sets preheat duration. The IC features self-adapting dead time adjustment, clock-accelerated customer test mode, and latched fault handling triggered by monitored thresholds - not software polling.
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. |
| Half-Bridge Drive Voltage | 900 V rated; supports direct driving of high-side MOSFETs in series-resonant fluorescent inverters without external level shifters. |
| LSCS Overcurrent Threshold | 0.8 V with 500 ns timeout; triggers latched shutdown to protect MOSFETs during short-circuit or end-of-life lamp failure. |
| Ignition Slope Sensitivity | 205 mV/µs ±25 mV/µs; enables precise filament warm-up control by detecting dI/dt during preheat phase. |
| Timer Range | Up to 40 seconds; digitally implemented with resistor-programmed accuracy stable over −25°C to +125°C ambient. |
| Dimming Thresholds | Dedicated analog comparators on LVS1/LVS2; detect lamp voltage asymmetry for analog dimming compatibility without external ADC. |
| Package | PG-DSO-19-1 (300 mil); 19-pin exposed-pad SOIC with creepage-enhanced layout for 2500 V RMS isolation compliance. |
Pinout & Package
ICB2FL02GXUMA2 is housed in a PG-DSO-19-1 (300 mil) package with integrated creepage distance enhancement and exposed thermal pad. Pin 16 is designated "Creepage distance" - a non-electrical mechanical feature, not a signal terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 LSCS | Inverter low-side current sense | Direct shunt connection; internal 0.8 V comparator with 500 ns blanking for MOSFET overcurrent protection. |
| 2 LSGD | Inverter low-side gate driver | Capable of sinking 1 A peak; drives N-channel MOSFET source-connected to GND. |
| 3 VCC | Main supply input | Internal LDO input; powers core logic and gate drivers; requires external 15 V ±10% supply. |
| 4 GND | Low-side reference ground | Return path for LSCS, LSGD, and control logic; separate from HSGND to avoid noise coupling. |
| 5 PFCGD | PFC gate driver output | Drives PFC switch MOSFET gate; optimized for DCM switching transitions and low shoot-through risk. |
| 6 PFCCS | PFC current sense input | Connects to PFC inductor shunt; detects zero-current crossing and peak current for DCM regulation. |
| 7 PFCZCD | PFC zero-current detection | Input for auxiliary winding sensing; enables precise DCM boundary detection without secondary-side components. |
| 8 PFCVS | PFC bus voltage sense | Monitors bulk capacitor voltage; triggers OVP (95%) and UVP (75%) protection and open-loop detection. |
| 9 RFRUN | Run frequency programming | Resistor-to-ground sets inverter operating frequency during normal lamp operation (e.g., 40–80 kHz). |
| 10 RFPH | Preheat frequency programming | Resistor-to-ground sets lower-frequency preheat mode (e.g., 25–45 kHz) to limit filament stress. |
| 11 RTPH | Preheat time programming | Resistor-to-ground sets preheat duration (up to 40 s); determines thermal ramp before ignition. |
| 12 RES | Lamp removal restart enable | Pull-down to restart inverter after lamp replacement; avoids manual power cycle in maintenance scenarios. |
| 13 LVS1 | Lamp voltage sense 1 | High-side lamp terminal monitoring; used with LVS2 to detect asymmetric voltage collapse during EOL or rectifier effect. |
| 14 LVS2 | Lamp voltage sense 2 | Low-side lamp terminal monitoring; differential comparison with LVS1 enables capacitive-load detection. |
| 15 AUX | Auxiliary output | Open-drain output for status signaling (e.g., lamp-on indication or fault flag to MCU). |
| 17 HSGND | High-side floating ground | Reference for HSGD; tied to source of high-side MOSFET; isolated from main GND by bootstrap or transformer. |
| 18 HSVCC | High-side supply input | Bootstrap or transformer-derived supply for high-side driver; must be ≥10 V for reliable HSGD operation. |
| 19 HSGD | Inverter high-side gate driver | Level-shifted driver capable of 900 V blocking; sinks 0.5 A peak to drive high-side MOSFET gate. |
| 20 NC | No connect | Unbonded pin; must remain unconnected per datasheet; no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| Digital timer accuracy | ±2% over −25°C to +125°C; eliminates need for external RC timing networks and improves batch consistency. |
| Customer test mode | Hardware-enabled clock acceleration (via RTPH pin) reduces functional test time by >60% without firmware changes. |

FAQ
What is the maximum allowable voltage on the HSGD pin?
The HSGD pin is rated for 900 V maximum blocking voltage, matching the IC's high-side driver specification. This rating is validated under continuous operation with proper PCB creepage (≥8 mm) and thermal management. Exceeding 900 V risks permanent damage to the level-shifting circuitry, and no transient overvoltage tolerance beyond this value is specified in the V1.2 datasheet.
Does ICB2FL02GXUMA2 support Power Factor Correction in Critical Conduction Mode (CRM)?
No - the ICB2FL02GXUMA2 supports only Discontinuous Conduction Mode (DCM) for PFC operation, as explicitly stated in Section 2.4.1 of the V1.2 datasheet. Its PFC control loop, ZCD detection, and THD correction features are architected exclusively for DCM; CRM operation is not implemented or characterized.
How is lamp end-of-life (EOL) detected using LVS1 and LVS2?
EOL detection uses differential comparison between LVS1 and LVS2: EOL1 (lamp overvoltage) triggers when LVS1 exceeds 320 V while LVS2 remains <100 V; EOL2 (rectifier effect) activates when both inputs show sustained asymmetry (>150 V difference) during run mode, indicating cathode degradation. These thresholds are fixed internal comparators, not resistor-programmable.
Can the customer test mode be activated without modifying hardware connections?
No - activation requires pulling the RTPH pin to GND (for preheat skip) or applying a specific voltage sequence to RTPH/RFPH pins (for clock acceleration), as defined in Sections 2.8.1 and 2.8.3. There is no register-based or I²C-accessible method; test mode is strictly hardware-controlled to ensure deterministic behavior during production testing.
