NCV7430 Automotive LIN RGB LED Driver The NCV7430 is a singlechip RGB driver intended for dedicated multicolor LED applications. The RGB LED driver contains a LIN interface (slave) for parametric programming of LED color and intensity. The device receives instructions through the LIN bus and www.onsemi.com subsequently drives the LEDs independently. The NCV7430 acts as a slave on the LIN bus and the master can request specific status information (parameter values and error flags). MARKING The LIN address of the NCV7430 can be programmed in the internal DIAGRAM memory of the device. 14 14 The NCV7430 is fully compatible with automotive requirements. 1 NCV74300 PRODUCT FEATURES SOIC14 AWLYWWG D2 SUFFIX LED Driver CASE 751A 1 3 Independent LED Current Regulators LED Currents Adjustable with External Resistors NCV7430 = Specific Device Code A = Assembly Location Power Dissipation Option with External Ballast Transistor WL = Wafer Lot Controller with OneTimeProgrammable Memory (OTP) Y = Year LED Modulation Controller for 3 LEDs WW = Work Week G = PbFree Package Full LED Calibration Support Internal LED Color Calibration via Matrix Calculation Intensity Control (linear or logarithmic) PIN CONNECTIONS Dimming and Color Transition (linear) Function with Programmable Transition Time 1 14 LED3C ANODE LIN Interface 2 13 LIN Physical Layer according to LIN 2.1/ SAE J2602 VBIAS LED1C OTPprogrammable Device Node Number 3 12 VBB LED2C OTPprogrammable Group Address 4 11 Diagnostics and Status Information LIN TST1 LIN Bus Short Circuit Protection to Supply and Ground 5 10 GND LED2R Protection and Diagnostics 6 9 Overcurrent Detection TST2 LED1R Short Circuit Detection to GND and VBB 7 8 GND LED3R Open LED Detection High Temperature Warning and Shutdown Retry Mode on Error Detection ORDERING INFORMATION Power Saving Device Package Shipping Sleep Mode Supply Current 10 A NCV7430D20G SOIC14 55 Units / Tube Compliant with 14 V Automotive Systems (PbFree) EMI Compatibility NCV7430D20R2G SOIC14 3000 / Tape & LIN Bus Integrated Slope Control (PbFree) Reel EMC Reduced LED Modulation Mode For information on tape and reel specifications, including part orientation and tape sizes, please Quality refer to our Tape and Reel Packaging Specification NCV Prefix for Automotive and Other Applications Requiring Brochure, BRD8011/D.
