Product description:

The INLC10AQ is a LED driver and controller chip. It is a mixed signal device in a 16 lead WETQFN package.

LED chains can be built up by daisy-chaining several INLC10AQ devices or other ISELED products via a differential bidirectional serial bus. For that purpose, the INLC10AQ device can also act as a converter of single ended to differential bus signals only. The chip provides three independent constant current sinks, each controlled via PWM.

In an LED chain, each device is individually addressable via the serial bus. A proprietary bus protocol is used, optimized for this particular application.

Features:

• 488Hz, 12-bit PWM

• Temperature compensation for red channel

• 8-bit brightness resolution for red, green, and blue LED

• Additional dimming function for accurate low light colors

• Maximum of 4079 devices in one LED chain

• Bidirectional, half-duplex, 2Mbps, CRC protected serial communication

• Support for 16 multicast address groups

• Eight times serial line oversampling for communication robustness

• On-die oscillator

• Built-in diagnostic functions

Applications:

• Ambient lighting

• Roof lighting

• Display backlight

• Functional lighting

• Converting of single ended to differential bus signals
