BTS5566G

SPI功率控制器 SPI Power Controller

Overview

The SPOC - is a five channel high-side smart power switch in PG-DSO-36-34 package providing embedded protective functions. It is especially designed to control standard exterior lighting in automotive

applications. It is designed to drive lamps up to 3

.

27W + 2*10W. Configuration and status diagnosis isdone via SPI. Additionally, there is a current sense signal available for each channel that is routed via a multiplexer to a single diagnosis pin. The SPOC - BTS5566G provides a fail-safe function via limp home input pin.

Basic Features
