SPI Power Controller for Advanced Light Control

T h e S P O C p r o d u cts are high-side smart power switches in P-DSO-36 package providing embedded protective functions. They are especially designed to control standard exterior front and rear lighting in automotive applications.

In order to use the same hardware with bulbs and LEDs, the device can be configured to bulb or LED mode. As a result, both load types are handled optimally in switching and diagnosis accuracy. not BTS 5566G

Configuration and diagnosis are done via SPI. Additionally, there is a current sense signal available for each channel that is routed via a multiplexer to one diagnosis pin. SPOC provide a secure limp home functionality via limp home input pin.
