Product status: Pre-Production
AS1163B is a mixed signal silicon device optimized for automotive dynamic lighting applications (interior, exterior, smart surface etc.). The basic purpose of AS1163B is to drive 6 LEDs organized in 2 channel triplets (RGB) or simply 6 single-color LEDs with an independent PWM dimming dynamic range up to 16 bits. AS1163B is often addressed with a different name: “SAID2”, an acronym which stands for Stand-Alone Intelligent Driver with 2 RGB triplets.
A daisy chain configuration of multiple AS1163B devices will enable cost effective implementation of complex dynamic lighting effects. AS1163B supports single layer slim PCB designs.The communication protocol supported by AS1163B (
OSP: Open System Protocol) is fully compatible with the ams OSRAM OSIRE E3731i. AS1163B will support additional features such as I²C gateway, parallel connection, power-rail feedback, analog readout. Each AS1163B device in the chain will be usable by the MCU to read and write an external I²C device, e.g. EEPROM, temperature sensor, Ambient Light Sensor.
