SC17XS6400BEK - Quad Channel High-Side LED Driver for Automotive BCM Lighting

The SC17XS6400BEK is a fourth-generation eXtreme switch designed specifically for modern automotive lighting applications. This advanced high-side switch provides a robust solution for controlling and diagnosing both incandescent bulbs and LEDs.

This device belongs to the expanding 12XS6 family of SMARTMOS achievements in automotive lighting drivers. It combines exceptional flexibility with enhanced diagnostic precision for reliable performance.

The SC17XS6400BEK incorporates a daisy chainable SPI interface that operates at 5.0 MHz for comprehensive digital control. The device offers extended digital and analog feedback mechanisms to ensure complete system visibility.

Engineered for efficiency, this driver features a low RDS(ON) specification of 17 mOhms. This low on-resistance enables significant power savings and reduced PCB space requirements at the module level.

The device supports a wide operating voltage range from 7.0 V to 18 V in normal mode. For enhanced flexibility, it extends operation from 6.0 V to 28 V in extended mode.

Advanced protection and diagnostic features include programmable overcurrent trip levels. The device also provides thermal shutdown protection and prewarning capabilities.

Output current sense is enhanced with a programmable synchronization signal and battery voltage feedback. The SC17XS6400BEK integrates watchdog functionality and Limp Home mode for fail-safe operation.

This device is packaged in a Pb-Free power-enhanced SOIC 32 package with an exposed pad. It is ELV compliant and includes NXP's product longevity program for a minimum of 15 years after launch.

The 16-bit SPI control allows management of overcurrent profiles, channel control, and 8-bit PWM duty-cycles. It also supports output-ON and OFF OpenLoad detections with comprehensive fault reporting.
