Overview

The SPOC - BTS5566G 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

• 8 bit serial peripheral interface (daisy chain capable SPI) for control and diagnostics

• CMOS compatible parallel input pins for each channel provide straightforward PWM operation

• Selectable AND- / OR-combination for parallel inputs (PWM control)

• Very low stand-by current

• Optimized electromagnetic compatibility (EMC) for bulbs

• Stable behavior at under voltage

• Device ground independent from load ground

• Green Product (RoHS-Compliant)

• AEC Qualified



Protective Functions

• Reverse battery protection with external components

• Short circuit protection

• Over load protection

• Multi step current limitation

• Thermal shutdown with latch

• Over voltage protection

• Loss of ground protection

• Electrostatic discharge protection (ESD)

Applications

• High-side power switch for 12 V grounded loads in automotive application

• Especially designed for standard exterior lighting like tail light, brake light, reverse light, parking light, license

plate lighting and turn signal indicators

• Replaces electromechanical relays, fuses and discrete circuits
