DESCRIPTION

· The MC12XS6D2 is a high-side switch designed for automotive lighting applications, offering enhanced control and diagnostics for incandescent lamps and LEDs.

· It features a daisy chainable SPI interface, extended digital and analog feedback, and robust safety mechanisms.

· The device includes output edge shaping for improved electromagnetic performance and a dynamic overcurrent threshold profile to handle inrush currents.

· It supports a Fail operation mode for continued functionality during communication loss with the external microcontroller.

· The 12XS6 family facilitates ECU design with compatible MCU software and PCB footprints across device variants.

FEATURES

· Dual and triple high-side switches with high transient current capability.

· 16-bit 5.0 MHz SPI control for overcurrent profiles, channel control, PWM duty-cycles, and fault reporting.

· Output current monitoring with programmable synchronization signal and battery voltage feedback.

· Limp Home mode and external smart power switch control.

· Operating voltage range of 7.0 V to 18 V with sleep current < 5.0 µA, extendable from 6.0 V to 28 V.

· Reverse polarity and ground disconnect protections up to 16 V.

· Compatible PCB footprint and SPI software driver within the family.

APPLICATIONS

· Low-voltage automotive lighting systems.

· Control of halogen lamps, incandescent bulbs, and LEDs.

· HID Xenon ballasts.
