SCR Gate Driver Wide selection of SCRs
(500 mA typical gate drive capability)

7. 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

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

10. 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: kW
RIN: W
Rset*: 301 kW
C1: nF
* Value will depend on sense coil characteristics and application

11. 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

12. 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

13. 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

14. 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

17. 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

18. 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
