analog, mixed-signal and power management mc07xsf517 triple 7.0 mohm and dual 17 mohm high-side switch overview the mc07xsf517 is the latest achievement in dc motors 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 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 modebut remains operational, controllable and protected. this new generation of high-side switch products facilitates ecu design due to compatible mcu software and pcb footprints for each device variant. this product is packaged in a pb-free power-enhanced soic package with an 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 in 4 vc c si cs b so rs tb cl k cs ns limp in 1 in 2 in 3 v pwr cp out1 out2 out3 out4 out5 out6 gnd out vpwr gnd csns smar t po we r 07xsf517 vc c so cs b sclk si r stb clk a/ d1 tr g1 a/ d2 po rt po rt po rt po rt po rt gnd sclk syncb ma in mc u vc c vpwr gnd 5 v regulator v pwr v pw r in m solenoi d led module dc mo tor resi st ive load bu lb sp ar e
