Freescale Semiconductor Technical Data Document Number: MC17XSF500 Rev. 2.0, 9/2013 Penta 17 mOhm High Side Switch 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. 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.
