analog, mixed-signal and power management mc17xsf500 penta 17 m high-side switch overview the mc17xsf500 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 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 utilized. 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 modebut remains operational, controllable and protected. this new generation of high-side switch products facilitates ecu design with its compatible mcu software and pcb footprint for each device variant. this product is packaged in a pb-free, power-enhanced soic package with exposed pad. target applications ? low-voltage exterior lighting ? low-voltage industrial lighting ? low-voltage automation systems ? halogen lamps ? incandescent bulbs ? light-emitting diodes (leds) ? hid xenon ballasts ? dc motors simplified application drawing
