LEDs and LED driver packages for advanced indicator applications
December 20, 2011 // Julien Happich
Rohm Semiconductor has launched a low current, high brightness chip LED, the SMLx family featuring various package sizes and colour ranges for use in advanced automotive cluster and indicator applications. The SMLTx, SMLMs and SMLZ families are able to emit OEM colours such as blue lagoon, ice blue, sapphire blue and blue green, including InGaN-based pure green.
Different package types and sizes provide designers with a wide range of devices in order to facilitate the optimum solution for their LED design. They come in PLCC2, Chip LED 0603, reflector 0603&0805, or lens type packages, with a profile height ranging from 0.55 to 1.9mm. Forward current IFmax range from 20 to 60mA, for a luminous intensity up to 4800 mcd. The LEDs operate in the -40 to +100° temperature range with a forward voltage of 2.0 to 3.5 at 20mA.
Rohm completes its offering with the BD8377 LED driver series, enabling a complete design solution for indicator lights in automotive cluster applications. This 12-channel 50mA/ch LED driver comes in a small SSOP-B20 package and supports cascade connections in order to increase the number of channels and the number of LEDs which can be driven and controlled. The devices features a 35V DMOS open drain output MOSFET for multiple driving and efficient power saving as well as low EMC noise with an output slew rate of 20V/usec.
