Technical Data  
Penta 17 mOhm High Side  
Switch  
17XSF500  
The 17XSF500 is the latest achievement in DC motor and lighting  
drivers. It belongs to an expanding family to control and diagnose  
various types of loads, such as incandescent lamps or 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.  
ENHANCED PENTA HIGH SIDE SWITCH  
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.  
EK SUFFIX (PB-FREE)  
98ASA00368D  
32-PIN SOICW-EP  
This new generation of high side switch products family facilitates ECU  
design thanks to compatible MCU software and PCB foot print for each  
device variant.  
Applications  
• Low voltage exterior lighting  
• Low voltage industrial lighting  
• Low voltage automation systems  
• Halogen lamps  
• Incandescent bulbs  
• Light-emitting diodes (LEDs)  
• HID Xenon ballasts  
This family is packaged in a Pb-free power-enhanced SOIC package  
with exposed pad which is End of Life Vehicles directive compliant.  
This device is powered by SMARTMOS technology.  
Features  
• Penta 17 mhigh side switches with high transient current capability  
• 16-bit 5.0 MHz SPI control of overcurrent profiles, channel control  
including PWM duty cycles, output-ON and -OFF OpenLoad  
detections, thermal shutdown and prewarning, and fault reporting  
• Output current monitoring with programmable synchronization signal  
and supply voltage feedback  
• DC motors  
• Limp Home mode  
• External smart power switch control  
• Operating voltage is 7.0 to 18 V with sleep current < 5.0 µA,  
extended mode from 6.0 to 28 V  
• -16 V reverse polarity and ground disconnect protections  
• Compatible PCB foot print and SPI software driver among the family
