DESCRIPTION

· The MC12XS6D1 is a high-side switch designed for automotive lighting applications, offering enhanced precision in controlling and diagnosing incandescent lamps and LEDs.

· It features a daisy chainable SPI interface at 5.0 MHz, extended digital and analog feedbacks, and robust safety mechanisms.

· The device includes dynamic overcurrent threshold profiles to manage inrush currents and programmable current sensing for each channel.

· In case of communication loss with the microcontroller, it enters a fail-safe mode, maintaining operational control and protection.

FEATURES

· Quad or penta high-side switches with high transient capability.

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

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

· Includes limp home mode, external smart power switch control, and operates from 7.0 V to 18 V with sleep current < 5.0 µA.

· Protections against -16 V reverse polarity and ground disconnect, with compatible PCB footprints and SPI software drivers across the family.

APPLICATIONS

· Low-voltage automotive exterior lighting.

· Control of halogen lamps, incandescent bulbs, LEDs, and HID Xenon ballasts.
