Analog, Mixed-Signal and Power Management MC07XSF517 Triple 7.0 mOhm and Dual 17 mOhm High-Side Switch Target Applications Overview • Low-voltage exterior lighting The MC07XSF517 is the latest achievement in DC motors and lighting drivers. It belongs to an • Low-voltage industrial lighting expanding family to control and diagnose various types of loads, such as incandescent lamps or • Low-voltage automation systems light-emitting diodes (LEDs) with enhanced precision. It combines flexibility through daisy chainable • Halogen lamps SPI 5 MHz, extended digital and analog feedbacks, safety and robustness. • Incandescent bulbs Output edge shaping helps to improve electromagnetic performance. To avoid shutting off the device • Light-emitting diodes (LEDs) upon inrush current, while still being able to closely track the load current, a dynamic overcurrent • HID xenon ballasts threshold profile is featured. Current of each channel can be sensed with a programmable sensing • DC motors 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 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.
