DESCRIPTION

· The 12XS6 is a Penta 40 mΩ high-side switch designed for automotive lighting drivers.

· It controls and diagnoses incandescent lamps and LEDs with enhanced precision.

· Features include daisy-chainable SPI 5.0 MHz, extended digital and analog feedbacks, safety, and robustness.

· It includes a dynamic overcurrent threshold profile to avoid shutdown during inrush current.

· The device remains operational in fail operation mode if communication with the microcontroller is lost.

· Compatible MCU software and PCB footprint facilitate ECU design.

FEATURES

· Penta 40 mΩ 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 from 7.0 V to 18 V with sleep current < 5.0 µA, extended mode from 6.0 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 exterior lighting.

· Incandescent bulbs (21 W).

· Light-emitting diodes (LEDs).
