LED driver allows complete programmability of 18 LEDs

Dialog Semiconductor Plc has launched a universal LED controller which provides complete programmability of up to 18 LEDs for the control of lightshows, backlights and signal LEDs in cellular handsets, handheld games and other portable devices requiring varying light sequences.

The DA9026 IC allows the control of sequences of LED patterns including combined RGB LEDs, with programmable variables such as pattern, repetition rate and intensity of each LED. This is done entirely within the device, removing the need for dedicated processing power.

The new universal LED controller especially addresses the growing complexity of LED management in applications such as clamshell handsets, lightshows, backlights (keypad and LCD) and signal LEDs, said the company. This is in response to a growing trend for the display or lights to flash in appropriate sequences to ring tones, music or different callers for example. In addition, for phones used in hands-free kits in the automotive environment, it allows manufacturers to control and customize the handset backlight to match color and level of illumination of the car's dashboard display.
