The BTS54040-LBF is a four channel high-side smart power switch in TSON-24-1 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 exterior lamps up to 27 W or the equivalent LED light.
8-bit serial peripheral interface (daisy chain capable SPI) for control and diagnosis
CMOS compatible parallel input pins for two channels
Selectable AND- / OR-combination for parallel inputs (PWM control)
Load type configuration via SPI (bulbs or LEDs) for optimized load control
Integrated control for one external smart power switch
