Description
The SPOC - BTS5572E is a five channel high-side smart power switch in PG-DSO-36-36 package providing
embedded protective functions. It is specially designed to control standard exterior lighting in automotive
applications. In order to use the same hardware, the device can be configured to bulb or LED mode. As a result,
both load types are optimized in terms of switching and diagnosis behavior.
It is designed to drive lamps up to 3*27W + 2*10W.
