DESCRIPTION

· The MC12XS6D4 is a dual 8.0 mΩ and dual 21 mΩ high-side switch designed for automotive lighting applications.
· It supports control and diagnostics for incandescent lamps and LEDs with enhanced precision.
· Features include daisy chainable SPI at 5.0 MHz, extended digital and analog feedback, and robust safety mechanisms.
· Output edge shaping improves electromagnetic performance, and a dynamic overcurrent threshold profile prevents shutdown during inrush currents.
· The device remains operational in fail mode if communication with the microcontroller is lost.
· Compatible MCU software and PCB footprints facilitate ECU design.

FEATURES

· Dual 8.0 mΩ and dual 21 mΩ high-side switches with high transient current capability.
· 16-bit 5.0 MHz SPI for overcurrent profiles, PWM duty cycles, open-load detection, thermal shutdown, and fault reporting.
· Output current monitoring with programmable synchronization and battery voltage feedback.
· Limp home mode and external smart power switch control.
· Operating voltage range: 7.08 V to 18 V (sleep current < 5.0 µA), extended mode: 6.08 V to 28 V.
· Reverse polarity and ground disconnect protections up to -16 V.
· Compatible PCB footprint and SPI software driver across the family.

APPLICATIONS

· Low-voltage automotive lighting.
· Halogen lamps and incandescent bulbs.
· Light-emitting diodes (LEDs).
· HID Xenon ballasts.
