Presentation Outline Fairchild Semiconductor GFI product background history New GFCI Products Value Proposition: Features and Benefits New Self Test GFCI Products FAN4149/FAN41501 GFCI controller with self test New Lighting product development FL5150 AC Dimmer Summary Product Development Roadmap

Fairchild GFI Products Fairchild has a long established business history with the GFCI Industry > 15 years Key New Products Key Established Products FAN4146 (ALCI) RV4141A FAN4146E (RCD, PRCD, ELCD) RV4145A FAN4147 (GFCI) FAN1851/1852 FAN4149/FAN41501 (ST GFCI) KA2803/KA2803 Applications Include GFCI & RCD Circuit Breakers GFCI & LCDI Portable Power Cords ALCI Personal Care Products Fairchild is now a member of the UL943 & UL943B Standards Technical Panel and will keep informed of new requirements for our customers

Fairchild GFI Products Fairchild has recently introduced several new GFI products to improve system cost, performance and board space: FAN4146 New product for the ALCI (UL943B) market (Personal care products) FAN4146E New product for the China (GB20044) and RCD (IEC61540) market FAN4147 New product for the GFCI (UL943) market (GFCI receptacles, power cords & circuit breakers)

Key FAN4146 & FAN4147 Features and Benefits Features Benefits Precision sense amplifier and reference Wider external component tolerance Built-in AC rectifier Fewer external components Built-in noise filter Improved nuisance tripping Space saving SuperSOTTM-6 package Reduced board space Low quiescent current Low wattage series resistor Adjustable sensitivity Programmable trip threshold SCR Gate Driver Wide selection of SCRs (500 mA typical gate drive capability)

FAN4146E versus 'old product' Differences Feature 'old Product' FAN4146E Process 40V Bipolar 16V Bipolar Package SO8 (8 pins) SSOT6 (6 pins) Size 5.0 x 6.2 mm^2 3.0 x 3.0 mm^2 Pitch 1.27 mm 0.95 mm Reference Emit-Base Zener Bandgap AC Rectifier External Diodes Internal Schottky Diode Noise Filter External Capacitors Internal Filters SCR Output PNP Current NPN Emitter Follower High Mirror with 100ns RC filter SCR Output Passive 4.7KW Passive & Active Low Discharge Resistor Discharge

Comparison of 'old product' versus FAN4146E Application 'old product' FAN4146E Cost Savings Component IC SOIC8 SSOT-6 ~ similar Diodes 4 0 ~ -4 cents Capacitors 4 (High Value) 1 (Low Value) ~ -6 cents Resistors 3 3 ~ similar >10¢ BOM Cost Savings Board Space Savings Improved Reliability and Manufacturability

Typical 'old product' versus FAN4146E Application Comparison Bulk cap Small MLCC 'Old Product' Application FAN4146E Application

Fairchild GFI Products FAN4146E Typical 2-wire Application for PRCD and RCCB Applications 230VAC 10mA to 30mA IFault Threshold Application Low BOM Component Requirement Typical Values: R1: 175 kW RIN: 470 W Rset*: 301 kW C1: 22 nF * Value will depend on sense coil characteristics and application

Fairchild GFI Products These three products are now code S Samples and demo boards are available now The FAN4146E provides for a very competitive solution for 2-wire RCD, PRCD and ELCD applications: Minimum number of components: Low BOM cost Board space savings Performance

Fairchild GFI Products Fairchild Semiconductor New Product Release in mid of 2014 FAN4149 and FAN41501 self test GFI Starting in 2015, all permanently connected GFCI products in North America will require self test capability Fairchild's new FAN41501 self test digital controller will provide the self test features required for the new UL943 standard

Fairchild GFI Products FAN4149 and FAN41501 Auto Monitoring GFCI Chip Set Solution Two IC chip solution for GFCI Auto Monitoring: FAN4149: Normal GFCI Detection, Always “On Guard” for ground fault protection and independent from auto monitoring cycle FAN41501: Auto Monitoring Digital Controller

Fairchild GFI Products FAN4149 and FAN41501 Key Features These devices are available in our Space Savings SOT23-6L and SuperSOT™ 6-pin packages The FAN4149 and FAN41501 products require a minimum number of components to provide: Continual Ground Fault Detection Self test cycle initiated after 1 second of applied power or reset and every 90 minutes thereafter Self test cycle includes testing for SCR, solenoid, sense transformer and FAN4149 ground fault controller End of Life Alarm Signal Auto reset of EOL signal when a successful manual test is detected

Fairchild GFI Products Ground Fault and Grounded Neutral Detection Auto Monitoring Digital Controller Independent from FAN4149 Functionality

Fairchild GFI Products FAN4149 and FAN41501 Product FAN4149 (Derivative of the FAN4147) 16 volt Bipolar Process 12V Internal Shunt, Internal Noise Filter, SCR Gate Drive High tolerate VOS sense amplifier (+/-180mV) for Direct DC coupling of sense XFMR FAN41501 0.5mm BiCMOS Process 5V Internal Shunt with Low Voltage Reset Control Logic for Self Test Timer and Self Testing of Critical GFCI components Samples and Demo Board are Available Now

Fairchild Lighting Products FL5150 IGBT / MOSFET AC Dimmer Controller Fairchild has a new Dimmer Controller IC in development to address new lighting requirements for non-resistive loads: LED products

Fairchild Lighting Products The Key FL5150 Features Include: IGBT or MOS Symmetric AC current control Separate pin for detection of an earth ground wire for the ZC threshold Less than 25 μA of earth ground leakage current required If an earth ground connection is not detected at start up, the FL5150 will use the sense pins for the ZC threshold detection Timer window comparator for ZC flicker reduction Selectable maximum duty at start up for AC load "kick start" Space saving SOIC 8 pin package Typically 240 dimmer pulse width steps with automatic ~1.1 second delay from minimum to maximum range No minimum “holding current” requirement
