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.

该产品是专门为要求高动态RGB照明场景的汽车内饰应用而设计的。该智能RGB产品除了R/G/B LED外，还集成了ams OSRAM的IC，这个嵌入式IC集成了三个R/G/B LED的驱动程序，还包括了R/G/B LED的光学测量数据。外部微控制器可以通过开放系统协议在菊花链拓扑结构中寻址和控制每个LED。开放协议允许微控制器读取这些数据，并运行任何颜色算法。它还允许读取回一个温度值来优化这个颜色算法。OSIRE E3731i在所有汽车生产国均遵守已知的专利及知识产权合规。特别指出，该产品并无与LED封装内部执行温度补偿或者通过LED内置控制器进行SPI通信等已知专利的冲突。

ams OSRAM OSIRE KRTB AELPS1.32 侧发光RGB产品专为汽车内饰应用而设计。它采用可独立控制的 LED 芯片，从而在颜色、驱动选择和通信控制方面具有极大的灵活性。OSIRE KRTB AELPS1.32 外形小巧，因此非常适用于到紧凑的光导中，实现超薄型设计。

OSIRE3323专为车载氛围灯设计。得益于紧凑尺寸，该产品适合在各种装配场景灵活使用。每颗LED在10mA和50mA下测得所有参数都可以通过印在LED上的二维码快速获取。这个设计极大减轻了用户在线测量LED参数的繁琐过程。

具有 Vλ 特性的硅光电二极管

The AS8579 is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the impedance that originates between a conducting surface (metallic object) and a human being. The IC captures the current of a metal object and applies algorithms to determine the capacitive and resistive information. The outcome information can be read through a SPI Interface that can be also used for IC configuration. This high precision performance sensor also supports a multitude of diagnostic features that meet standard functional safety requirements. The capacitive sensing IC is specifically designed to function in an electro-magnetic environment (EMC) with high magnetic disturbances. This allows the sensor to distinguish in a hands-on application if the driver‘s hand is on the steering wheel or not. The AS8579 is available in an SSOP24 package and operates at a supply voltage of 5V.
