描述 Description

The BTS54220-LBA 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 65 W and 27 W, HIDL or the equivalent LED light.

特性 Features

· 8-bit serial peripheral interface (daisy chain capable SPI) for control and diagnosis.
· PWM driving possible through direct inputs or via SPI
· Selectable AND-/ OR- combination for the parallel inputs (PWM control)
· Load type configuration via SPI (bulb or LEDs)
· Very low Stand By current
· Fail Safe activation via Limp Home pin and  configuration via input pins only
· Green Product (RoHS-Compliant)
· AEC Qualified.

应用 Application

·Highside power switch for 12 V grounded loads
·Especially designed for standard exterior lighting like high beam, low beam, indicator, parking light, using bulbs, HIDL or LEDs
·Further automotive and industrial applications such as heating, motor driving, energy and power distribution
·Replaces electromechanical relays with fuses, as well as discrete chip sets
