Automotive LED driver with SPI dimming and 24A per channel
The Infineon BTS5572EAUMA1 is a DC DC regulator configured as a switched-capacitor charge pump, designed for automotive LED lighting applications where five independent output channels each deliver up to 24A. Dimming is controlled via an SPI interface, allowing digital brightness adjustment per channel — useful for adaptive headlamps or interior ambient lighting where PWM or analog dimming would add external components. The device integrates internal switches and operates from a 5.5V to 28V supply, covering the typical automotive battery range including load-dump transients.
Infineon has marked the BTS5572EAUMA1 as Obsolete. Buyers needing this exact order code must source it through surplus or broker channels. No stock-holding claim is made.
