The 12XS6 is the latest SMARTMOS achievement in automotive lighting drivers.

It belongs to an expanding family, which helps to control and diagnose

incandescent lamps and light-emitting diodes (LEDs), with enhanced precision.

It combines flexibility through daisy chainable SPI 5.0 MHz, extended digital and

analog feedbacks, safety, and robustness.

Output edge shaping helps to improve electromagnetic performance. To avoid

shutting off the device upon inrush current, while still being able to closely track

the load current, a dynamic overcurrent threshold profile is featured. Current of

each channel can be sensed with a programmable sensing ratio. Whenever

communication with the external microcontroller is lost, the device enters a fail

operation mode, but remains operational, controllable, and protected.

This new generation of high-side switch products family facilitates ECU design

due to compatible MCU software and PCB foot prints for each device variant.

Features

? Quad or penta high-side switches with high transient capability

? 16-bit 5.0 MHz SPI control of overcurrent profiles, channel control including

PWM duty cycles, output on and off open load detections, thermal shutdown

and prewarning, and fault reporting

? Output current monitoring with programmable synchronization signal and

battery voltage feedback

? Limp home mode

? External smart power switch control

? Operating voltage is 7.0 V to 18 V with sleep current < 5.0 μA, extended mode

from 6.0 V to 28 V

? -16 V reverse polarity and ground disconnect protections

? Compatible PCB foot print and SPI software driver among the family

Applications

? Low-voltage automotive exterior lighting

? Halogen lamps
